[0068] Before turning to the accompanying drawings (which illustrate exemplary embodiments in detail), it should be understood that this application is not limited to the details or methods set forth in the specification or shown in the drawings. It should also be understood that terminology is used for descriptive purposes only and should not be considered limiting.
[0069] Overview
[0070] Referring generally to the accompanying drawings, the lifting device includes a deployable operator station. The deployable operator station may include two frame assemblies pivotally connected to each other, with a first frame assembly pivotally connected to a base of the lifting device. The frame assembly pivotally connected to the base may be driven by a linear electric actuator for automatic deployment. A second frame assembly may be selectively rotatably connected to the first frame assembly via an engagement mechanism, which a user may selectively disengage and then manually deploy. The deployable operator station may also include various housing or enclosure components configured to interlock with each other to isolate the deployable operator station and prevent unauthorized access to various input devices of the lifting device located at the deployable operator station. The lifting device may include multiple user interfaces. For example, the lifting device may include a first user interface located at a platform or implement assembly and a second user interface at the operator's seated or standing position when operating the lifting device. The lifting device may be a fully electric lifting device including a lifting mechanism that uses an electric linear actuator and / or a motor to raise or lower a implement assembly located at an end of the lifting mechanism.
[0071] The lifting device may be a fully electric lifting device and may include a first battery bank at a base assembly and a second battery bank at a turntable assembly. The turntable assembly may include a slip ring drive (e.g., an electromechanical slip ring drive) that rotatably connects the turntable member to the base assembly or frame. The lifting device may be positioned on the turntable member such that operation of the slip ring drive drives the turntable member and the lifting device to rotate or pivot relative to the base assembly or frame. The first battery bank positioned on the base assembly may be configured to provide power to electrical components of the base assembly (e.g., for drive, steering, or shaft locking operations). The second battery bank positioned on the turntable assembly may be configured to provide power to electrical components of the lifting device (e.g., for raising or lowering operations).
[0072] The first battery pack can be configured to connect to a facility power source for charging both the first and second battery packs. A charger can connect to the facility power source and transfer charging power or energy to the first battery pack. The first battery pack can supply power to any electrical component of the base assembly via an inverter. The first battery pack can serve as a main power source and can be used to supplement or recharge the second battery pack as needed. For example, a controller can monitor the battery level of the second battery pack and recharge it using the energy supplied by the first battery pack. The second battery pack can be recharged by the first battery pack via a slip ring drive. Specifically, the first battery pack can transfer power to the turntable assembly's charger via an inverter and a slip ring drive. The turntable assembly's charger can use the power supplied via the slip ring drive to charge the second battery pack. Thus, the slip ring drive can act as or be used as a prime mover to drive the relative rotation between the turntable component and the base assembly's frame, and to facilitate the transfer of power from the first battery pack to the second battery pack.
[0073] In some embodiments, the controller is also configured to prevent or limit operation of the lifting device based on the battery charge level of the second battery pack. For example, if the battery charge level of the second battery pack drops below a first threshold, the controller may prevent operation of the lifting mechanism components of the lifting device. The controller may also determine whether the first battery pack has sufficient capacity to charge the second battery pack, and whether the first battery pack can be used to charge the second battery pack. If the first battery pack does not have sufficient capacity to charge the second battery pack, the controller may determine that the first battery pack should be connected to a power source for recharging and may notify the operator of the lifting device (e.g., by operating a display screen, providing a visual alarm, providing an audible alarm, etc.). If the battery charge level of the second battery pack drops below a second threshold level and the first battery pack still does not have sufficient capacity to recharge the second battery pack, the controller may completely restrict operation of the lifting device until the first battery pack is connected to a power source for recharging.
[0074] In some examples, the lifting device can be used as part of an autonomous or semi-autonomous construction site fleet. The lifting device may include a controller configured to communicate via one or more wireless communication protocols enabling remote monitoring and control of the lifting device. The lifting device may include a communication gateway that monitors the lifting device's status (e.g., battery level, health, location, etc.) and transmits this status to one or more networked devices (e.g., computers, smartphones, tablets, etc.). These same networked devices can be used to send remote commands, which may include drive, lift, or other instructions that can then be executed by the lifting device without the need for an operator's presence. In some examples, remote commands may be sent to a human-machine interface on the lifting device, providing task-specific instructions that can then be read or otherwise presented to an operator located within the lifting device. In other examples, the lifting device is configured to operate in conjunction with auxiliary equipment (e.g., drones, mobile devices, etc.) that can provide the lifting device with tasks and specific target locations for autonomous operation. The lifting device may include one or more cameras that can be used to provide viewpoints on networked devices, allowing for precise manual remote control of the lifting device.
[0075] Lifting device
[0076] Specific reference Figure 1 The lifting device 10 shown includes a base assembly 12 (e.g., base, main body, vehicle, etc.), lifting equipment 14 (e.g., telescopic boom, articulated boom, boom rod, boom, etc.), and implement assembly 16 (e.g., platform, platform assembly, work platform, fork assembly, equipment, etc.). Figure 1 As shown, the lifting device 10 is configured as a mobile overhead work platform (MEWP), wherein the implement assembly 16 is a work platform. The implement assembly 16 can be replaced with different implement assemblies (e.g., fork assemblies) to convert the lifting device 10 from an MEWP to a material handling machine (MH). When the lifting device 10 is an MH, the implement assembly 16 can be a fork carriage, a pair of forks for a material handling machine, etc., which can be used as a multi-functional attachment interface into which a work platform with forklift recesses can be attached. Additionally, the fork carriage can be used for attaching other tools, making the implement assembly 16 interchangeable.
[0077] The base assembly 12 includes a frame 20 (e.g., bracket, structural member, support member, chassis, frame member, etc.) and a plurality of traction elements 22 (e.g., wheels, pedals, rotatable members, rollers, etc.). The base assembly 12 also includes a prime mover (e.g., electric motor, internal combustion engine, hydraulic motor, pneumatic motor, etc.), shown as an electric motor 24. The electric motor 24 may be configured to provide mechanical power (e.g., rotational kinetic energy) to the traction elements 22 (e.g., via a gearbox, power transmission system, one or more gearboxes, etc.) for transporting the lifting device 10. The electric motor 24 may also provide mechanical power for operating the lifting equipment 14, the steering system of the lifting device 10, the deployment of the deployable operator station of the lifting device 10, etc., or for any other function, feature, etc., of the lifting device 10 that requires mechanical power to operate. The electric motor 24 may represent a single electric motor or a collection of electric motors configured to consume or receive electrical energy from one or more batteries, power batteries, capacitors, electrical storage devices, electrical storage systems, etc. (shown as energy storage device 40) to generate mechanical power. The traction element 22 can receive mechanical power from the motor 24 and rotate relative to the frame 20. The traction element 22 can be pivotally or rotatably coupled to the frame 20, so that the traction element 22 can rotate relative to the frame 20 to facilitate the driving or transport operation of the lifting device 10 (e.g., transporting the lifting device 10 from one site to another).
[0078] The traction elements 22 may include a first pair or a front pair of traction elements and a second pair or a rear pair of traction elements. These pairs of traction elements 22 can be rotatably or pivotally connected to corresponding shafts (e.g., front and rear shafts, respectively), which are fixedly connected to, integrally formed with, welded to, fastened to, etc., the frame 20. One or two shafts may include one or more steering members (e.g., tie rods, elongated members, etc.) configured to pivot or rotate the traction elements about a steering axis to indicate the direction of rotation of the lifting device 10. In this way, the motor 24 and the traction elements 22 can facilitate the transport of the lifting device 10 from one location to another.
[0079] Still refer to Figure 1The base assembly 12 includes an operator station, shown as a deployable operator station 100 (e.g., a cab, housing, enclosure, space, area, station, standing station, platform, etc.). The deployable operator station 100 can be fixedly connected to the frame 20 or the main body of the lifting device 10, allowing an operator to sit or stand at the deployable operator station 100 and be transported with the lifting device 10 during travel and turning. The deployable operator station 100 may include a main body, frame, sidewalls, roof, doors, windows, etc., or may otherwise form an enclosure for the operator. The deployable operator station 100 may be positioned to the left or right of the lifting device 10, or centered above the frame 20. In some embodiments, the deployable operator station 100 can be deployed or transitioned between an undeployed state, position, mode, etc., and an deployed state, position, mode, etc. The deployable operator station 100 may be a complete or partial enclosure providing protection or shielding for environmental elements for the operator.
[0080] Still refer to Figure 1 The lifting device 14 is or includes a pair of hinged telescopic members, shown as a first telescopic member 58 and a second telescopic member 60, which are pivotally or hingedly connected at an intermediate member 44. The second telescopic member 60 includes an outer member 26 (e.g., the first member) and an inner member 28. The inner member 28 may be accommodated within the internal volume of the outer member 26 and may be configured to slide, translate, etc., relative to the outer member 26. In some embodiments, the inner member 28 and the outer member 26 are slidably connected such that the overall length of the second telescopic member 60 may be increased or decreased to facilitate raising or lowering the implement assembly 16. The inner member 28 and the outer member 26 may be configured to extend or retract by operation of a prime mover, linear electric actuator, electric motor, hydraulic cylinder, pneumatic cylinder, etc. (shown as linear electric actuator 38). The linear electric actuator 38 can draw power or electrical energy from one or more batteries, power sources, energy storage devices, etc. of the lifting device 10 (e.g., from the electrical energy storage device 40) and use the electrical energy to operate to extend or retract, thereby driving the internal member 28 to translate relative to the external member 26 (and thereby raising or lowering the machine assembly 16 to the raised position).
[0081] The outer member 26 may receive the inner member 28 at a first end or proximal end, and may be rotatably or hingedly connected to the intermediate member 44 at a second end or opposite end. Specifically, the outer member 26 may be hingedly or rotatably connected to the upper part or corner of the intermediate member 44. The outer member 26 may be driven by a linear actuator, electric motor, linear electric actuator, pneumatic actuator, hydraulic cylinder, etc. (shown as linear electric actuator 30) to rotate or pivot relative to the intermediate member 44, thereby raising or lowering the tool assembly 16. The linear electric actuator 30 may be pivotally connected to the outer member 26 at a first end and pivotally connected to a portion of the intermediate member 44 at a second end.
[0082] The lifting device 14 may include an intermediate member, an elongated member, etc. (shown as intermediate member 36). Intermediate member 36 may be pivotally connected to an inner member 28 via a hinge, pin, hinge connector, etc. (shown as pin 32). The inner member 28 may extend at a first end into the internal volume of the outer member 26 and be rotatably connected to intermediate member 36 at an opposite or second end. Intermediate member 36 may be configured to be driven by linear electric actuator 42 to rotate about pin 32, thereby pivoting or rotating the tool assembly 16. Linear electric actuator 42 may be pivotally connected at a first end to intermediate member 36 and at a second end to inner member 28, such that extension or retraction of linear electric actuator 42 drives intermediate member 36 and tool assembly 16 to rotate relative to inner member 28 about pin 32.
[0083] Still refer to Figure 1The first telescopic member 58 of the lifting device 14 may include an outer member 48 and an inner member 46. The outer member 48 may receive the inner member 46 through an internal volume such that the inner member 46 is slidably connected to the outer member 48. The inner member 46 may be rotatably or hingedly connected to an intermediate member 44 (e.g., at the bottom of the intermediate member 44). In some embodiments, a first end or proximal end of the inner member 46 extends into the outer member 48, and a second end or distal end of the inner member 46 is rotatably or hingedly connected to the intermediate member 44. The outer member 26 may also be hingedly or rotatably connected to the intermediate member 44 (e.g., at the upper end of the intermediate member 44). In this way, the intermediate member 44 may be a link or intermediate member that is hinged, rotatably, or pivotally connected to the outer member 26 at a first end (e.g., the upper end) and hinged, rotatably, or pivotally connected to the inner member 46 at a second end (e.g., the lower end). The intermediate member 44 may be an upright structural member forming a connection between the second telescopic member 60, formed by the outer member 26 and the inner member 28, and the first telescopic member 58, formed by the inner member 46 and the outer member 48, or the device. The inner member 46 and the outer member 48 may form a telescopic member that is the same as or similar to the second telescopic member 60 formed by the inner member 28 and the outer member 26. The first telescopic member 58 (formed by the outer member 48 and the inner member 46) may extend from the front or forward portion of the lifting device 10 in a rearward direction (e.g., from the base assembly 12 or the frame 20), while the first telescopic member (formed by the outer member 26 and the inner member 28) may extend from the rear or region of the lifting device 10 in a forward direction (e.g., from the intermediate member 44).
[0084] Still refer to Figure 1 The external member 48 can be rotatably, pivotally, or hingedly connected to the base assembly 12 via the support member 50. The support member 50 can be fixedly connected to the base assembly 12 or the frame 20 and may include portions configured to receive and pivotally connect to the ends of the external member 48. The lifting device 14 also includes a linear electric actuator 52 configured to be pivotally or hingedly connected at one end to the base assembly 12 (e.g., to the support member 50) and at a second or opposite end to the external member 48. The linear electric actuator 52 can be configured to extend or retract to pivot the external member 48 relative to the support member 50.
[0085] Still refer to Figure 1The lifting device 14 may include a linear actuator 54 configured to extend or retract to drive an inner member 46 to translate relative to an outer member 48. In some embodiments, the linear actuator 54 is positioned within the outer member 48 such that extension of the linear actuator 54 drives translation of the inner member 46 to increase the overall length of the inner member 46 and the outer member 48, while retraction of the linear actuator 54 drives translation of the inner member 46 to decrease the overall length of the inner member 46 and the outer member 48. It should be understood that the linear actuators 52 and 54 may be the same as or similar to any other linear actuator described herein (e.g., linear actuator 42) and may be configured to receive or obtain electrical energy or power from the energy storage device 40. In some embodiments, the linear actuators 52 and 54 are also configured to receive control signals from the controller 200 and use these control signals to operate to perform the requested function of the lifting device 14.
[0086] like Figure 45 As shown, the lifting device 10 is configured to move between an extended working configuration and a more compact traveling position. In the working configuration, the lifting device 14 and the implement assembly 16 typically extend outward and forward from the frame 20 and forward from the lifting device 10. In the compact traveling position, the implement assembly 16 retracts inward, closer to the frame 20. The intermediate member 36 can rotate rearward, causing the implement assembly to rotate upward on a portion of the frame 20. Similarly, the intermediate member 44 can also rotate rearward, causing the outer member 26 and the entire lifting device 14 and implement assembly 16 to face rearward toward and above the frame 20. Conventional lifting devices have long booms, which typically results in the implement assembly being positioned very far forward of the lift chassis. This conventional configuration makes transportation difficult because the distance between the chassis and the implement severely limits road transport on trailers. Significant space savings are achieved by using the multi-telescopic boom of the lifting device 10 to lift the device 14. The implement assembly 16 retracts and rotates to be positioned almost completely (e.g., at least 50%) above the frame 20. Therefore, due to the significantly limited footprint of the lifting device 10, trailers or other types of transport are significantly improved compared to conventional lifts.
[0087] Specific reference Figure 2 The lifting device 10 is shown in the form of a material handling machine, wherein the implement assembly 16 includes a pair of elongated members, shown as forks 18. The implement assembly 16 can be fixedly connected to the intermediate member 36 of the lifting device 14, such that the implement assembly 16 is raised or lowered by the operation of the lifting device 14. The implement assembly 16 may also include a bucket, a platform (e.g., such as...) Figure 1 The aerial work platform shown, drills, augers, or any other equipment.
[0088] Refer again Figure 1 The lifting device 10 may include a controller 200 configured to operate the lifting device 10 to perform the various functions described herein. For example, the controller 200 may monitor the state of the energy storage device 40, battery health, state of health, state of charge, capacity, etc., and may operate a human-machine interface (HMI) (e.g., such as...). Figure 3 The controller 200 includes an HMI 500, user interface, display screen, etc., to provide the operator of the lifting device 10 with indications or notifications regarding the status or performance characteristics of the energy storage device 40. The controller 200 can also generate control signals for the motor 24 and the steering system (e.g., which may include linear actuators to pivot the traction element 22 to indicate the direction of rotation). The controller 200 can also generate control signals for any one of linear actuators 52, 54, 30, 38, or 42 to operate the lifting device 14 (e.g., raise or lower the implement assembly 16). The controller 200 can generate control signals to operate the lifting device 10 in response to receiving user input for operating the lifting device 10 via an HMI or user input device (e.g., HMI 500). The HMI or user input device may be located at the operator station 34 or on the outer surface of the lifting device 10 (e.g., on the operator station 34 or the outer surface of the lifting device 10). Figure 3 (As shown in HMI 500). The HMI or user input device may include any number of buttons, handles, touchscreens, joysticks, user input devices, displays, steering wheels, etc., configured to receive user input and provide signals instructing the controller 200 to the user input. The controller 200 can then use the signals to determine which operations of the lifting device 10 are requested to be performed, and can generate control signals for various controllable elements of the lifting device 10 (e.g., motor 24, linear actuator 30, linear actuator 38, linear actuator 42, etc.) to perform the requested functions or operations.
[0089] Deployable operator station
[0090] Reference Figures 2 to 3 , Figures 11 to 23 and Figures 34 to 45 The deployable operator station 100 can be used in situations such as Figure 3 The first position or state shown (e.g., collapsed state, folded state, collapsed position, folded position, etc.) and such as Figure 2Operation or transition between the indicated second position or state (e.g., deployed state, deployed position, etc.). Advantageously, the deployable operator station 100 can be converted to a retracted position to restrain or limit access to various control panels, HMIs, operator panels, control devices, etc., of the lifting device 10, which may be located within or at the deployable operator station 100. This can prevent the possibility of unauthorized individuals potentially accessing and operating the lifting device 10 (e.g., reducing the possibility of theft, providing protection for various control panels, HMIs, operator panels, control devices, etc., reducing the possibility of damage to various components of the deployable operator station 100, etc.).
[0091] Specific reference Figures 2 to 3 and Figure 11 The deployable operator station 100 can be used Figure 2 The unfolded position shown and Figure 3 and Figure 11 The deployable operator station 100 may include a first housing member 106 (e.g., a first planar member, a first housing member, a cover member, a cover, etc.), a second housing member 108 (e.g., a planar member, a housing member, a cover, etc.), and a third housing member 109 (e.g., a planar member, a housing member, a cover, etc.). The first housing member 106, the second housing member 108, and the third housing member 109 may be configured to switch between folded or stowed positions when the deployable operator station 100 is switched to a folded or stowed position (e.g., ...). Figure 3 and Figure 11 When the deployable operator station 100 is in a folded or stowed position (as shown), they interlock, abut, engage, or contact each other. In some embodiments, the first housing member 106 is configured to interlock, abut, engage, or contact each other when the deployable operator station 100 is in a folded or stowed position (as shown). Figure 3 and 11 (As shown) Switch to the expanded position (e.g.) Figure 2 As shown, the first housing member 106 can rotate or pivot about axis 126 when the deployable operator station 100 is deployed. Specifically, when the deployable operator station 100 is deployed, the first housing member 106 can rotate about axis 126 in direction 129. The first housing member 106 can be hinged or pivotally connected to the base assembly 12 such that when the deployable operator station 100 is deployed, the first housing member 106 can be driven to rotate or pivot about axis 126. Alternatively, as shown... Figures 34 to 45 As shown, the first housing component 106 can be pivotally connected to the base assembly 12 at the rear of the first housing component 106.
[0092] The second housing member 108 can be fixedly connected to the base assembly 12 or the frame 20 and can remain stationary when the deployable operator station 100 is deployed or folded / retracted. For example, the second housing member 108 can be a vertically extending sidewall that remains stationary when the deployable operator station is folded or retracted (e.g., Figure 3 and Figure 4As shown), this sidewall interlocks, abuts, engages, and mates with the first housing member 106. The third housing member 109 can be fixedly connected to the first frame assembly 102 (e.g., a rollover protection structure, ROPS) of the deployable operator station 100, which rotates about axis 122. Therefore, when the deployable operator station 100 is switched between deployed and folded positions, the third housing member 109 can rotate or pivot about axis 122. When the deployable operator station 100 is folded (e.g., switched to a folded position), the third housing member 109 can rotate or pivot about axis 122. Figures 3 to 4 When in the position shown, the third outer shell member 109 can interlock, abut, contact, join, or mate with the first outer shell member 106 and the second outer shell member 108 to form an outer shell, structure, housing, container, etc., thereby enclosing various components of the deployable operator station 100. Alternatively, as Figures 34 to 35 As shown, the third housing member 109 is omitted, and the first housing member 106 is rotated rearward relative to the second housing member 108 to transition to the deployed position. In some examples, the first housing member 106 is biased toward the open position by a spring or other biasing element. Therefore, unlocking or de-locking the first housing member 106 from the second housing member 108 allows the first housing member 106 to rise naturally and passively from the second housing member 108 to the deployed position. Alternatively, a motor and / or actuator can be used to raise the first housing member 106 from the second housing member 108. One or more buttons may be positioned along the outside of the second housing member 108, said buttons that can be pressed or otherwise manipulated by a user to unlock the first housing member 106 and transition the first housing member 106 to the open position. In some examples, the buttons are positioned below a locked, shielded cabinet, which more generally prevents unauthorized access to the buttons and the deployable operator station 100. In other examples, one or more of the locks and / or actuators can be remotely controlled and can be switched from a locked position to an unlocked position using wireless communication. Various types of locking mechanisms can be used to open and switch the first housing member 106 to the unfolded position, including mechanical key locks and automatic or electronic locks with RFID readers, Bluetooth readers, near field communication (NFC) tag readers, etc.
[0093] In addition to the deployable operator station 100, the lifting device 10 may include a deployable or selectively accessible storage compartment 113. For example... Figure 37 and Figure 39As shown, the storage compartment 113 is typically configured similarly to the deployable operator station 100, having a first outer shell member 117 rotatably and / or hingedly connected to the second outer shell member 119. The first outer shell member 117 and the second outer shell member 119 together define the storage compartment 113, which can be used to store tools, fuel, food, and / or other necessary materials for performing tasks on-site. The storage compartment 113 can be incorporated into a type that does not include a motor-driven lifting device 10 (e.g., a fully battery-powered type, etc.).
[0094] In some examples, such as Figures 34 to 35 and Figures 37 to 40 As shown, the lifting device 10 includes one or more sets of steps 121 to assist users in ascending the deployable operator station 100 or accessing the storage compartment 113. The steps 121 may be positioned on one or both sides of the lifting device 10 and may be directly mounted to or otherwise formed within the base assembly 12. The steps 121 extend downward toward the ground beneath the lifting device 10. Alternatively, the steps 121 may be selectively deployed. For example, the steps 121 may be part of a retractable assembly that extends downward only when the first housing member 106 is in an open or deployed position. When the first housing member 106 is rearranged to a folded or stowed position, the steps 121 may automatically retract inward to reduce the outer perimeter of the lifting device 10 and further restrict unauthorized access to or damage to the deployable operator station 100 or storage compartment 113, as these components are lifted off the ground. In some examples, a button or switch may be positioned within the deployable operator station 100 such that once a user is correctly positioned within the deployable operator station 100, the step 121 can be retracted. In some embodiments, the seat 124 within the deployable operator station 100 includes sensors (e.g., pressure sensors, switches, load sensors, etc.) for detecting load on the seat 124. When a load is detected on the seat 124 (which corresponds to a user sitting within the deployable operator station 100), the step 121 retracts. When no load is detected, the step 121 unfolds (or remains unfolded) to allow the user easy entry into or exit from the deployable operator station 100.
[0095] Specific reference Figure 2The deployable operator station 100 may include a first frame assembly 102 and a second frame assembly 104 (e.g., a fall protection structure, FOPS, head protection structure, etc.). The first frame assembly 102 may be rotatably or pivotally coupled to a base assembly 12 (e.g., with frame 20) at a first end, and pivotally or rotatably coupled to a second frame assembly 104 at a second end or distal end. The second frame assembly 104 may be configured to rotate or pivot relative to the first frame assembly 102 about an axis 120. Thus, when the deployable operator station 100 transitions between an deployed position and a folded / collapsed position, the first frame assembly 102 and the second frame assembly 104 may rotate or pivot relative to the base assembly 12 about an axis 122, while the second frame assembly 104 may be configured to rotate or pivot relative to the first frame assembly 102 about an axis 120. The deployable operator station 100 may also include a seat 124.
[0096] Specific reference Figure 3 The lifting device 10 may include a rotator assembly, a platform rotator assembly, a turntable, etc., shown as a turntable assembly 800. The turntable assembly 800 may include a turntable member 803 configured to pivot or rotate about a central axis 62. The lifting device 14 can be connected to the base assembly 12 via the turntable assembly 800 to allow the lifting device 14 to rotate relative to the base assembly 12 about the central axis 62. Specifically, a support member 50 may be fixedly connected to the turntable member 803 such that the lifting device 14 can rotate or pivot relative to the frame 20 about the central axis 62. A deployable operator station 100 may be positioned on the turntable member 803 such that rotation of the turntable member 803 relative to the base assembly 12 or relative to the frame 20 causes rotation of the deployable operator station 100 relative to the frame 20.
[0097] Still refer to Figure 3 The turntable assembly 800 may include a platform rotator, a motor, an electric motor, etc., shown as a turntable motor 64. The turntable motor 64, shown as an electric motor, consumes electrical energy from the energy storage device 40 to generate rotational kinetic energy to drive the turntable member 803 to rotate relative to the frame 20. The turntable motor 64 may also be an internal combustion engine, a hydraulic motor, a pneumatic motor, etc., or any other prime mover. In some embodiments, the turntable motor 64 receives a control signal from the controller 200, causing the controller 200 to operate the turntable motor 64 (e.g., to rotate the turntable assembly 800 by a predetermined or desired angle based on user input or a user request). The turntable motor 64 may be configured to drive the turntable member 803 via a gearbox, transmission, spur gear, ring gear, worm gear, etc., or any other gear or power transmission mechanism or combination thereof. Rotation of the turntable assembly 800 relative to the frame 20 facilitates access to a raised position angularly offset relative to the lifting device 10.
[0098] Specific reference Figures 5 to 9 According to an exemplary embodiment, a portion of a deployable operator station 100 is shown in more detail. The deployable operator station 100 includes a frame, a base, a support structure, etc., shown as a support structure 110. The support structure 110 is fixedly connected to the base assembly 12 or the frame 20 and provides structural support for the deployable operator station 100. The support structure 110 extends vertically a distance from the planar member 111. The support structure 110 may be formed of multiple structural members that are stacked and have different widths. The support structure 110 is configured to support a first frame assembly 102 and a second frame assembly 104.
[0099] The first frame assembly 102 is hingedly or pivotally connected to the support structure 110, such that the first frame assembly 102 can rotate or pivot relative to the support structure 110 about axis 122. Figures 12 to 16 As shown, the first frame assembly 102 may include a first frame member, a first elongated member, etc. (shown as first frame member 112a) and a second frame member, a second elongated member, etc. (shown as second frame member 112b). The first frame member 112a and the second frame member 112b are laterally offset from each other by a distance 130. The first frame member 112a and the second frame member 112b are each pivotally or rotatably connected to the support structure 110 at a first end and pivotally or rotatably connected to the second frame assembly 104 at opposite or distal ends. The first frame member 112a and the second frame member 112b may each be pivotally connected to the support structure 110 by a pin 134. The first frame assembly 102 may also include one or more laterally extending frame members 132 extending between the first frame member 112a and the second frame member 112b. The laterally extending frame members 132 may provide additional structural support for the first frame assembly 102.
[0100] The first frame member 112a and the second frame member 112b are each fixedly connected to or integrally formed with their corresponding connecting members 118. Specifically, the first frame member 112a is fixedly connected to or integrally formed with the first connecting member 118a, and the second frame member 112b is fixedly connected to or integrally formed with the second connecting member 118b. The first frame assembly 102 is pivotally or hingedly connected to the second frame assembly 104 via the first connecting member 118a and the second connecting member 118b. The first frame assembly 102 is pivotally or hingedly connected to the support structure 110 via pins 134 at the first ends of the first frame member 112a and the second frame member 112b, and pivotally or hingedly connected to the second frame assembly 104 via the first connecting member 118a and the second connecting member 118b at the second ends or distal ends of the first frame member 112a and the second frame member 112b.
[0101] Specific reference Figures 14 to 18 Each of the connecting members 118 includes a corresponding pin, cylindrical member, rotatable member, interface member, etc., shown as pin 136. Pin 136 may define an axis 120 about which the second frame assembly 104 rotates or pivots relative to the first frame assembly 102. Each of the connecting members 118 may include parallel or laterally offset members, with corresponding portions of the second frame assembly 104 extending between the members. The corresponding portions of the second frame assembly 104 can be rotatably coupled to the first frame assembly 102 via the connecting members 118. The deployable operator station 100 also includes an engagement mechanism 180 configured to selectively lock or restrict relative rotation between the first frame assembly 102 and the second frame assembly 104. Engagement mechanism 180 can be switched between a locked position or state and an unlocked or released position or state by user input. Engagement mechanism 180 facilitates locking the angular orientation of the second frame assembly 104 relative to the first frame assembly 102 in various predetermined positions (e.g., as shown). Figure 12 , Figure 14 and Figure 15 The position of the folded or collapsed angle of the second frame assembly 104 relative to the first frame assembly 102, as shown, and as Figures 16 to 17 The second frame component 104 is shown in its unfolded angular position relative to the first frame component 102.
[0102] Specific reference Figures 15 to 17 The second frame assembly 104 includes one or more frame members 114 and one or more laterally extending frame members 116. The laterally extending frame members 116 may have a square or circular cross-sectional shape and may provide additional structural support for the frame members 114. In some embodiments, each frame member 114 includes a corresponding hole through which the laterally extending frame member 116 extends. Figure 15 As shown, a pair of outermost members 115 of the frame members 114 are housed within a connecting member 118 and are rotatably or pivotally connected to the connecting member 118 by a pin 136. Each of the frame members 114 located between the outermost members 115 may include a slot 158 along which rods, beams, elongated members, etc., of the engagement mechanism 180 (shown as rods 154) can extend and translate. The frame members 114 may be evenly spaced laterally between the outermost members 115. Each of the outermost members 115 may also include an opening, hole, aperture, drill hole, etc. (shown as a hole 156), in which rods 154 can be inserted and stored (e.g., by a user, operator, technician, etc.).
[0103] Specific reference Figures 17 to 18The engagement mechanism 180 is shown in more detail according to an exemplary embodiment. The engagement mechanism 180 is configured to facilitate interlocking the first frame assembly 102 and the second frame assembly 104 at predetermined relative angular positions. The engagement mechanism 180 can be switched between an engaged or locked state and an unlocked state via user input at lever 154. For example, a user can switch the engagement mechanism 180 to the unlocked state by applying a force in direction 160 to lever 154 to translate lever 154 along slot 158. Once the engagement mechanism 180 is switched to the unlocked state, the user can apply a rotational force or torque to the second frame assembly 104 to rotate the second frame assembly 104 relative to the first frame assembly 102 to various predetermined angular positions (e.g., unfolded angular positions and folded or stowed angular positions). Once the user has rotated the second frame assembly 104 to one of the predetermined angular positions, the user can release lever 154 to lock the second frame assembly 104 at the current angular position relative to the first frame assembly 102.
[0104] Still refer to Figures 17 to 18 The engagement mechanism 180 includes connecting members 118. Each connecting member 118 includes a first notch, a first groove, etc. (shown as an unfolding groove 148) and a second notch, a second groove, etc. (shown as a retracting groove 151). The second frame assembly 104 includes a housing member, a guide member, etc., which is shown as a guide member 138. The guide member 138 is fixedly connected to the inward or inward-facing surface of the outermost member 115, such that the guide member 138 is configured to rotate or pivot together with the outermost member 115 when the second frame assembly 104 rotates or pivots relative to the first frame assembly 102 about axis 120. The guide member 138 includes an internal volume, a track, a channel, an opening, a hollow portion, etc., and is configured to receive a plunger, an engagement member, an interlocking member, etc. (shown as a plunger 140). The plunger 140 may be configured to translate along the inner surface or inner periphery of the guide member 138 or to be slidably connected to the inner surface or inner periphery of the guide member 138. The plunger 140 may have a circular cross-sectional shape, and the guide member 138 may have an internal volume with a corresponding cross-sectional shape, allowing the plunger 140 to translate relative to the guide member 138. In some embodiments, the plunger 140 is configured to translate relative to the guide member 138 to engage the unfolding slot 148 and the retracting slot 151, interlock with the unfolding slot 148 and the retracting slot 151, be positioned within the unfolding slot 148 and the retracting slot 151, be adjacent to the unfolding slot 148 and the retracting slot 151, be contacted with the unfolding slot 148 and the retracting slot 151, be received within the unfolding slot 148 and the retracting slot 151, etc. When the plunger 140 translates at the unfolding slot 148 or the retracting slot 151 to engage with the connecting member 118, the angular position of the second frame assembly 104 relative to the first frame assembly 102 is locked or fixed.
[0105] In some embodiments, a first end 146 of the plunger 140 is configured to interlock with, engage with, cooperate with, and be received within the expansion and retraction slots 148 and / or 151, etc. Opposite ends 142 of the plunger 140 may extend outward from opposite sides of the guide member 138 and may be securely connected, attached, fixed, etc., by cables, ropes, etc. (shown as tension member 144). The tension member 144 extends in the same direction as the frame member 114 or the outermost member 115 of the second frame assembly 104. The tension member 144 may extend through aligned or corresponding holes in each laterally extending frame member 116 and may be securely connected to the rod 154. The first end of the tension member 144 is fixedly connected or attached to the plunger 140 at the opposite end 142, while the second end, distal end, or opposite end of the tension member 144 is fixedly connected, attached, or secured to the rod 154. In this manner, translation of the rod 154 in direction 160 (e.g., by a user inputting force in direction 160) is transmitted through the tension member 144 and translates the plunger 140 relative to the guide member 138, causing the first end 146 of the plunger 140 to translate out of engagement with the unfolding slot 148 or the retracting slot 151. This allows the user to selectively translate the plunger 140 out of engagement with the connecting member 118, thereby changing the engagement mechanism from a locked state to an unlocked state. The user can then hold the rod 154 in the translated position and rotate the second frame assembly 104 until the plunger 140 approaches the desired one of the unfolding slot 148 or the retracting slot 151. Once the second frame assembly 104 is rotated to the angular position of the unfolding slot 148 or the retracting slot 151 as required by the operator, the operator can release the lever 154, causing the plunger 140 to engage with the desired one of the unfolding slot 148 or the retracting slot 151.
[0106] Specific reference Figure 18 The engagement mechanism 180 may include a spring or resilient member, shown as spring 161. Spring 161 may bias plunger 140 relative to guide member 138 for translation in one direction, such that plunger 140 engages deployable slot 148 or retractable slot 151. In this way, engagement mechanism 180 may be spring-loaded such that release of lever 154 causes engagement mechanism 180 to automatically transition to a locked state (depending on the current angular position of second frame assembly 104 relative to first frame assembly 102). In some examples, second frame assembly 104 may also be vertically adjustable relative to first frame member 112a and second frame member 112b. Second frame assembly 104 may include a proximity sensor to detect the operator's position within deployable operator station 100, and the position of second frame assembly 104 will automatically adjust to reduce the distance between the operator's heads, thereby providing further safety.
[0107] Specific reference Figure 14 The deployable operator station 100 may include a linear electric actuator 164 configured to deploy, rotate, drive, pivot, etc., relative to the support structure 110, of the first frame assembly 102 and the second frame assembly 104 for deployment. Specifically, the linear electric actuator 164 may be configured to drive the first frame assembly 102 to rotate about axis 122 to partially deploy the deployable operator station 100. The linear electric actuator 164 may draw electrical energy from the energy storage device 40 and use the electrical energy to generate linear motion. The linear motion may be transmitted to the first frame assembly 102 to drive the first frame assembly 102 to rotate about axis 122 (e.g., along direction 123), thereby deploying the deployable operator station 100. For example, the linear electric actuator 164 may be translationally fixedly coupled and pivotally coupled at opposite ends to the support structure 110 (or planar member 111) and the first frame assembly 102 (e.g., first frame member 112a or second frame member 112). Thus, the extension and retraction of the linear actuator 164 drives the first frame assembly 102 and the second frame assembly 104 to rotate about axis 122 to unfold or retract / fold up. In some embodiments, the controller 200 is configured to generate a control signal for the linear actuator 164 to unfold the deployable operator station 100 in response to user input received from the HMI 500. In some embodiments, the controller 200 generates a control signal to unfold the deployable operator station 100 only if the operator or user provides credentials indicating that the user has the right to access (e.g., via the HMI 500). In other embodiments, the HMI is physically fixed (e.g., in a locked box) such that only a keyed user with the right to access the HMI can unfold the deployable operator station 100.
[0108] Still refer to Figure 14 The second frame assembly 104 can be manually rotated about axis 120 to complete the deployment of the deployable operator station 100. For example, the deployable operator station 100 can be automatically partially deployed (e.g., by operation of linear electric actuator 164) and then fully deployed by manually actuating or translating lever 154 and rotating the second frame assembly 104 relative to the first frame assembly 102.
[0109] Specific reference Figure 16The deployable operator station 100 may include a backrest 166, a first armrest 128a, a second armrest 128b, and a seat 168. The backrest 166 may be fixedly connected to a laterally extending frame member 133. In some embodiments, both the backrest 166 and the laterally extending frame member 133 are rotatably connected to a laterally extending member 170 extending between the first frame member 112a and the second frame member 112b. In this way, the backrest 166 and the laterally extending frame member 133 may pivot or rotate between an deployed position and a folded position (e.g., automatically pivoting or rotating by operation of a motor, linear actuator, etc.). In other embodiments, the laterally extending frame member 133 is fixedly connected to or integrally formed with the first frame member 112a and the second frame member 112b.
[0110] Still refer to Figure 16 The first handrail 128a and the second handrail 128b can be hinged, pivotally connected, or rotatably connected to the first frame member 112a and the second frame member 112b, respectively. The first handrail 128a and the second handrail 128b can be in an extended position (e.g., Figure 9 (as shown) and folded or stowed positions (such as...) Figure 8 The first armrest 128a and the second armrest 128b are configured to rotate or pivot between an unfolded position and a folded or stowed position, or to rotate automatically between the unfolded position and the folded or stowed position, for example, by the operation of a corresponding linear actuator or motor that may receive a control signal generated by the controller 200 in response to receiving user input via the HMI 500.
[0111] Still refer to Figure 16 The seat 168 can be rotatably or pivotally connected to the lateral extension member 170, and can be in an unfolded position (e.g. Figure 16 (as shown) and folded or stowed positions (such as...) Figure 15 The chair tray 168 can be switched between the unfolded position and the folded or stowed position manually, or it can be switched automatically between the folded or stowed position and the unfolded position (e.g., by operation of a linear electric actuator).
[0112] Specific reference Figure 15The deployable operator station 100 may include multiple rubber components, rubber stops, absorbent components, etc., shown as rubber stops 172. Rubber stops 172 may be positioned along a laterally extending frame member 174 (e.g., spaced apart along the laterally extending frame member 174), the laterally extending frame member 174 extending between first frame members 112a and second frame members 112b, near the ends of the first frame members 112a and second frame members 112b that include pins 134 (e.g., the ends of the first frame members 112a and second frame members 112b that are pivotally connected to the support structure 110). Rubber stops 172 may be configured to engage, abut, contact, etc., corresponding portions of the surface of the seat tray 168 when the seat tray 168 is rotated to the deployable position.
[0113] Specific reference Figure 20 A portion of the deployable operator station 100 is shown in more detail.

The first armrest 128a includes a cover, support, etc., shown as support 178. Support 178 may be made of rigid or flexible material and provides an area for the operator to support their arms.
[0114] Specific reference Figure 20 and Figure 21 The first armrest 128a may include a joystick or pivotable user input device, shown as joystick 190. Joystick 190 is a user input device configured to pivot relative to the first armrest 128a to operate the lifting device 14. In some embodiments, the first armrest 128a is an armrest for a user's right hand, allowing the user to operate the lifting device 14 with their right hand. Joystick 190 can be pivoted or rotated by the user and can generate input signals for controller 200. Controller 200 receives input signals from joystick 190 and operates the lifting device 14 (e.g., various controllable elements or linear electric actuators configured to raise or lower the lifting device 14) based on the input signals obtained from joystick 190.
[0115] Still refer to Figure 20 and Figure 21The first handrail 128a may include a handle rotation input device 194. In some embodiments, the handle rotation input device 194 is configured to receive user input (e.g., rotation between various predetermined selections or positions) to select different functions of the lifting device 14 or to select different functions of the joystick 190. For example, when the handle rotation input device 194 is in a first position, the joystick 190 can operate the lifting device 14 or operate a first function of the lifting device 14, while in a second position, the joystick 190 can be used to operate different subsystems or systems of the lifting device 10 or operate a second function of the lifting device 14.

For example, the drive and steering lever 188 may be actuated or pivoted by a user's thumb and may generate an input signal for the controller 200. The controller 200 may use the input signal to generate control signals for the drive system and / or steering system of the motor 24 of the lifting device 10 or the drive traction element 22 for drive and / or steering operations. A user may actuate the drive and steering enable switch 186 to generate an input signal for the controller 200, thereby activating or deactivating the drive and steering operations of the lifting device 10.

Slip ring 418 may be communicatively coupled to the first battery pack 408 and may be configured to exchange discrete digital control signals with the first battery pack 408. Advantageously, slip ring 418 may be a high-current slip ring, sized to accommodate traction or battery current (e.g., greater than 500 amperes) to facilitate continuous rotation of turntable assembly 800.

The turntable control module 428 may be configured to provide control signals to any one of the slip ring 418, actuator 430, third charger 420, or ignition module 426 via the CANBUS of the lifting device 10.
[0127] Compared to the first battery pack 408, the second battery pack 424 can be a secondary or smaller battery pack. For example, the second battery pack 424 can be a 7.4 kWh battery pack comprising four modules. Advantageously, the split battery system 400 uses the first battery pack 408 located at the base assembly 12 (or on the frame 20) and the second battery pack 424 located at the turntable assembly 800 to drive the slip ring 418 to perform the turntable function of the lifting device 10.

The slip ring drive 812 may be configured to consume electrical energy to generate rotational kinetic energy, thereby causing the first portion 814 to rotate relative to the second portion 816.
[0136] Specific reference Figure 8 According to an exemplary embodiment, one of the energy storage compartments 822 is shown in more detail. It should be understood that the left energy storage compartment 822a and the right energy storage compartment 822b can be constructed similarly such that anything described with respect to the left energy storage compartment 822a can be said to refer to the right energy storage compartment 822b, and vice versa.

[0140] In some embodiments, the energy storage compartment 822 further includes a base battery management system 834. For example, the base battery management system 834 may be positioned at the energy storage compartment 822 and supported by a first frame member 828 and a second frame member 826.
[0141] Specific reference Figures 7 to 8 The base assembly battery 806 can be configured to serve as the main power source for any motors, actuators, systems, functions, etc., of the base assembly 12 and / or turntable assembly 800. For example, the base assembly battery 806 can supply power to the slip ring drive 812 to rotate the turntable member 803 relative to the frame 20. The base assembly battery 806 can also be configured to supplement or recharge the turntable battery 802.

[0144] Still refer to Figure 9 The turntable assembly 800 includes a turntable battery management system 840 configured to monitor the state of the turntable battery 802 or control the discharge of the turntable battery 802 (e.g., based on sensor data). The turntable battery management system 840 may be the same as or similar to the base battery management system 834. The turntable assembly 800 also includes a turntable master controller 842 responsible for operating various controllable elements (e.g., linear electric actuators of the lifting device 14) that draw power from the turntable battery 802.
[0145] The turntable component 803 can support the turntable battery 802, charger 804, manual on / off switch 832, turntable electronic control switch 830, turntable battery management system 840, or turntable main controller 842. In this way, the turntable battery 802, charger 804, manual on / off switch 832, turntable electronic control switch 830, turntable battery management system 840, and turntable main controller 842 can rotate or pivot relative to the frame 20 about the central axis 62 together with the turntable component 803.
[0146] Reference Figures 4 to 9 The turntable battery 802 can be replenished or recharged by the base assembly battery 806 via a power inverter 810 (e.g., inverter 410), a slip ring drive 812, and a charger 808 (e.g., charger 808 of base assembly 12 or charger 804 of turntable assembly 800). The power inverter 810 can be configured to convert DC power from the base assembly battery 806 into AC power and supply the AC power to the slip ring drive 812. The slip ring drive 812 can transfer AC power or electrical energy from the power inverter 810 to the charger 804. The charger 804 can receive AC power or electrical energy from the slip ring drive 812 and recharge or replenish the turntable battery 802, allowing the lifting device 14 or its various linear electric actuators to draw power from the turntable battery 802. The controller 200, turntable battery management system 840, turntable main controller 842, base component controller 820, base battery management system 834, base control module 412, or turntable control module 428 can collaboratively or individually adjust the energy balance between turntable battery 802 and base component battery 806.
[0147] Refer again Figure 8 The energy storage compartment 822 can be a modular base energy storage compartment. Each energy storage compartment 822 may include six base assembly batteries 806, a charger 808, a manual on / off switch 824, and two electronically controlled switches 836. The lifting device 10 may include two energy storage compartments 822 located on either side of the frame 20. The manual on / off switch 824 may be a manual disconnect switch for disconnecting the base assembly batteries 806.
[0148] Specific reference Figure 5 and Figure 9The lifting device 14 may be configured to draw power from the turntable battery 802 when operating to perform various lifting device functions, such as raising or lowering the implement assembly 16, extending or retracting the external member 26 relative to the internal member 28, rotating the turntable assembly 800, etc. Various linear electric actuators or motors performing these functions may draw power from the turntable battery 802 as long as the energy level or charge of the turntable battery 802 remains above a certain level. The turntable battery 802 may be supplemented by the base assembly battery 806 to maintain the turntable battery 802 above this level. If the turntable battery 802 cannot provide sufficient electrical power to the lifting device 14 or the various controllable elements required to perform the functions described herein, and supplementation from the base assembly battery 806 is unavailable, the controller 200 may maintain the reserved energy to operate the lifting device 14 in a limp mode or a restricted mode (e.g., allowing the lifting device 14 to operate only to lower the implement assembly 16). If the energy level of the turntable battery 802 decreases further and replenishment from the base assembly battery 806 remains unavailable, the functionality of the lifting device 14 can be disabled or limited by the controller 200 until energy replenishment becomes available. If the battery charge (e.g., state of charge) of the base assembly battery 806 falls below a threshold level, the controller 200 can also block the delivery of power to various linear electric actuators of the base assembly 12 (e.g., drive actuators, steering actuators such as electric actuator 722, shaft locking actuators).
[0149] During normal operation of the base assembly 12 (such as driving and steering), the energy required to start the various controllable elements of the base assembly 12 (e.g., linear electric actuators, motor 24, etc.) can be provided by the base assembly battery 806. If the energy storage of the base assembly battery 806 is low or below a certain level and energy replenishment is unavailable, the controller 200 can disable the operation of the base assembly 12 until replenishment becomes available.
[0150] When the lifting device 10 is connected to a facility energy source (e.g., connected to a power outlet or charging station via socket 402), the charger 808 can charge the base module battery 806 using energy provided by the facility energy storage. Simultaneously, the power inverter 810 can convert the DC voltage or DC power of the base module battery 806 into AC power with a sufficiently low current to be consumed by the slip ring drive 812. The AC power can then be transferred via the slip ring drive 812 to the turntable battery 802 or the charger 804 to replenish the turntable battery 802. The charger 804 can then charge the turntable battery 802 until both the turntable battery 802 and the base module battery 806 reach 100% state of charge.
[0151] When the lifting device 10 is not connected to the facility's power source, the turntable battery 802 can still be supplemented or recharged by the base assembly battery 806 as described herein. In some embodiments, the controller 200 or the control system of the lifting device 10 operates the split battery system 400 such that the turntable battery 802 is maintained at 75%-80% state of charge, as long as the base assembly battery 806 has a charge of 10% or more. Once the base assembly battery 806 drops below 10% state of charge, energy transfer from the base assembly battery 806 to the turntable battery 802 can be stopped.

[0153] Reference Figures 1 to 3 The implement assembly 16 can interchangeably accommodate different implements or equipment, or can be replaced by different implements. For example, in Figures 2 to 3 The diagram shows a tool assembly 16 configured with a fork 18, such that the lifting device 10 is configured to perform material handling (e.g., configured as a material handling machine). However, tool assembly 16 can be removed and different tool assemblies (e.g., such as...) can be installed.

In some embodiments, when the implement assembly 16 is the platform assembly 90, the deployable operator station 100 can be switched to a folded or stowed mode, position, or state. When the implement assembly 16 is the platform assembly 90, the worker 502 can operate the lifting device 10 from the platform assembly 90 by operating an HMI located at the platform assembly 90 or by using a mobile device (e.g., a smartphone) wirelessly connected to the controller 200.

The fork 18 may be configured to facilitate detachable attachment of pallets, supporting materials, etc., so that materials can be placed or removed from the raised position 504. When the lifting device 10 is configured as a material handling machine with the fork 18, the lifting device 10 can be operated from the deployable workstation 100. Specifically, when the lifting device 10 is configured as a material handling machine, the deployable workstation 100 can be switched to an deployed state, position, or mode, so that the worker 502 can control or operate the lifting device 10 through various user input devices located at the deployable operator station 100.
[0156] Refer again Figures 2 to 3 The figure shows a deployable operator station 100 positioned on the right side 150 of the lifting device 10. The deployable operator station 100 may be positioned on the right side 150 of the lifting device 10, or alternatively on the left side 152 of the lifting device 10. In a preferred embodiment, as shown, the deployable operator station 100 is positioned on the right side 150 of the lifting device 10.
[0157] Refer again Figures 1 to 3 The diagram illustrates that the lifting device 10 is configured as a fully electric telescopic forklift, which uses linear electric actuators 52, 54, 30, and 38 to raise or lower the implement assembly 16. However, the lifting device 10 may be similarly configured as a hydraulic telescopic forklift, wherein the linear electric actuators 52, 54, 30, and 38 are replaced by hydraulic cylinders. In other embodiments, if the lifting device 10 is a hybrid telescopic forklift, one or more of the linear electric actuators 52, 54, 30, or 38 are replaced by hydraulic linear actuators. In still other embodiments, the lifting device 10 is configured as an electro-hydraulic or hybrid telescopic forklift. In some embodiments, the lifting device 10 is configured as a MEWP with a linear lifting assembly. When the lifting device 10 is in MEWP mode (e.g....), Figure 4 (as shown) or MH mode (such as) Figure 5As shown, the lifting device 10 can be configured as a two-wheel steering telescopic boom forklift, such that two of the traction elements 22 (e.g., a front pair or a rear pair) are configured to receive steering input and indicate the direction of rotation of the lifting device 10. In some embodiments, the lifting device 10 is configured as a four-wheel steering telescopic boom forklift, such that both pairs of traction elements 22 (e.g., a front pair and a rear pair) are configured to receive steering input to indicate the direction of rotation of the lifting device 10. In some embodiments, the lifting device 10 is configured as a two-wheel drive telescopic boom forklift, such that only two of the traction elements 22 receive rotational kinetic energy (e.g., from the motor 24 or each from a corresponding motor 24) for transporting the lifting device 10. In some embodiments, the lifting device 10 is configured as a four-wheel drive telescopic boom forklift, such that all four traction elements 22 receive rotational kinetic energy (e.g., from the motor 24 or each from a corresponding motor 24) for transporting the lifting device 10. In some embodiments, the motor 24 is positioned near each traction element 22 such that each traction element 22 can be driven independently by its corresponding motor 24. The electric motor 24 can be a high-speed, high-efficiency electric motor (e.g., an electric motor with the highest efficiency at the desired travel or transport speed).
[0158] Steering system
[0159] Now refer to Figures 29 to 33 According to an exemplary embodiment, a steering system 700 is shown in more detail. The steering system 700 is configured to pivot the traction element 22 to perform steering. The steering system 700 includes one or more frame members, control arm assemblies, hub assemblies, joints, etc., shown as a steering knuckle 706. Any frame member (e.g., laterally extending frame members 702 / 704) may be a component or portion of the frame 20. The traction element 22 is rotatably coupled to the steering knuckle 706. The traction element 22 is configured to rotate about an axis 790 relative to the steering knuckle 706. The traction element 22 may frictionally engage with the ground, thereby driving the lifting device 10 when it is driven to rotate by the electric motor 24.
[0160] Steering knuckle 706 is configured to rotate / pivot about axis 720 relative to the laterally extending frame members 702 / 704 to facilitate steering of the lifting device 10. Steering knuckle 706 can be rotatably connected to the laterally extending frame members 702 / 704 via bearings. Electric motor 24 can be configured to pivot together with steering knuckle 706 as steering knuckle 706 rotates about axis 720. Steering knuckle 706 is driven by linkages, control arms, rigid members, etc. (shown as steering member 792) to pivot about axis 720. Steering member 792 includes a first bow-shaped member 708a and a second bow-shaped member 708b (e.g., a curved member, an arc member, an arch member, etc.). Bow-shaped member 708 can have a generally bow-shaped shape, a curved shape, a curved shape with a constant radius, a curved shape with a non-constant radius, an angled shape (e.g., two straight or curved portions offset at an angle), etc. Steering member 792 is configured to pivotally engage with connection portion 712 of steering knuckle 706 about central axis 711. Steering member 792 may be engaged with an elongated member, cylinder, pin, rod, etc. (shown as pin 714), pin 714 extending through a corresponding hole in connection portion 712 between first bow-shaped member 708a and second bow-shaped member 708b. In some embodiments, pin 714 is fixedly engaged with bow-shaped member 708 and rotatably engaged with a hole / drill hole in steering knuckle 706. In other embodiments, pin 714 is fixedly engaged with steering knuckle 706 and rotatably engaged with a hole / drill hole in bow-shaped member 708. Both first bow-shaped member 708a and second bow-shaped member 708b include a connecting end 796. Connecting end 796 may include a hole, drill hole, aperture, etc., extending through connecting end 796 and configured to engage with pin 714. In some embodiments, a bearing (e.g., a sleeve bearing, a ball bearing, etc.) is disposed in a bore of the connecting portion 712 and configured to engage with a pin 714 extending between the first arcuate member 708a and the second arcuate member 708b. The pivoting / rotational engagement between the steering knuckle 706 and the first arcuate member 708a and the second arcuate member 708b facilitates relative rotation between the steering knuckle 706 and the steering member 792 about the central axis 711.
[0161] The electric motor 24 is configured to drive the traction element 22. The electric motor 24 can be mounted between laterally extending frame members 702 and 704. The laterally extending frame members 702 / 704 are the ends of one (e.g., front and rear) of the laterally extending frame members 710. The laterally extending frame members 710 can extend substantially along the entire lateral width of the lifting device 10. The laterally extending frame members 710 provide structural support between the traction element 22 and the base assembly 12. The laterally extending frame members 710 extend along the lateral axis 780 of the lifting device 10.
[0162] Steering member 792 has a generally arcuate shape and extends between electric actuator 722 (e.g., electric linear actuator, linear electric steering actuator, etc.) and steering knuckle 706. Steering member 792 is configured to connect with a rod, cylinder, extension member, push rod, etc. (shown as rod 726) of electric actuator 722. Steering member 792 can be fixedly connected to the end, connecting portion, U-clamp, attachment portion, etc. (shown as end 730) of rod 726. Rod 726 is configured to extend and retract relative to the body, housing, frame, main member, external member, etc. (shown as body 724) of electric actuator 722. Rod 726 can be housed in the body 724 of electric actuator 722 and driven by electric motor 732 to extend and retract. Electric motor 732 can be configured to engage with a gear that drives a drive nut (not shown). The drive nut can drive rod 726 to extend or retract.
[0163] The end 730 of the rod 726 is configured to be received between the first bow-shaped member 708a and the second bow-shaped member 708b. The first bow-shaped member 708a and the second bow-shaped member 708b may be substantially parallel to each other and extend outward between the electric actuator 722 and the traction element 22. The end 730 may be fixedly connected to the first bow-shaped member 708a and the second bow-shaped member 708b. In some embodiments, the end 730 is fixedly connected to the first bow-shaped member 708a and the second bow-shaped member 708b by fasteners 728 (e.g., bolts, rivets, screws, etc.), the fasteners 728 extending through the end 730, the first bow-shaped member 708a and the second bow-shaped member 708b. In some embodiments, two or more fasteners 728 are used to fix the end 730 of the rod 726 to the steering member 792 (i.e., to the first bow-shaped member 708a and the second bow-shaped member 708b). In other embodiments, the end 730 of the rod 726 and the steering member 792 are integrally formed, welded, or otherwise fixedly attached.
[0164] The fixed connection between the end 730 of the lever 726 and the steering member 792 prevents rotation between the lever 726 and the steering member 792. Advantageously, this helps to reduce the lateral load applied to the electric actuator 722. This can reduce the possibility of any internal components of the electric actuator 722 failing due to excessive lateral load / force.
[0165] An electric actuator 722 is configured to be pivotally coupled to a longitudinally extending frame member 742. The longitudinally extending frame member 742 extends longitudinally outward from a transverse frame member 710. The longitudinally extending frame member 742 may extend from the center point of the transverse frame member 710. The longitudinally extending frame member 742 may extend outward from the transverse frame member 710 (e.g., in a forward direction 750). The longitudinally extending frame member 742 may be removably coupled to the transverse frame member 710 (e.g., by fasteners), integrally formed with the transverse frame member 710, or otherwise connected / coupled to the transverse frame member 710. The electric actuator 722 is disposed between the longitudinally extending frame members 742a and 742b. The body 724 of the electric actuator 722 may be positioned between the longitudinally extending frame members 742a and 742b.
[0166] Pin 798 may extend at least partially (or completely) through a hole in the actuator 722 and a corresponding hole in the longitudinally extending frame member 742. The actuator 722 is configured to pivot, rotate, and so on about an axis 776 relative to the longitudinally extending frame member 742. When the actuator 722 extends and retracts, it may pivot about the axis 776 in either direction. The axis 776 may be defined to extend through pin 798. Pin 798 may be fixedly connected to the actuator 722 and is configured to be rotatably connected to bearings, mounting members, rotatable connecting members, etc. (shown as connecting member 740). Connecting member 740 may be disposed on the outside of the longitudinally extending frame member 742. For example, connecting member 740a may be disposed on the upper or outer surface of the longitudinally extending frame member 742a, while connecting member 740b may be disposed on the lower or outer surface of the longitudinally extending frame member 742b. Pin 798 can be slidably connected to a hole, drill hole, or opening in the body 724 of the electric actuator 722. In other embodiments, pin 798 is fixedly connected to a hole in the body 724. In other embodiments, pin 798 slides into the inner surface of a hole in the body 724. Pin 798 can be rotatably connected to a connecting member 740. The connecting member 740 may include a bearing (e.g., ball bearing, roller bearing, sleeve bearing, etc.) configured to connect to pin 798. The connecting member 740 can be connected to a longitudinally extending frame member 742.
[0167] The longitudinally extending frame members 742a and 742b may be substantially parallel to each other and define a receiving region between them. The receiving region is configured to indirectly accommodate the body 724 of the electric actuator 722. A pin 798 may extend through at least a portion or substantially the entire receiving region defined between the longitudinally extending frame members 742a and 742b.
[0168] When the electric actuator 722 extends (e.g., lever 726 extends relative to body 724), the electric actuator 722 can rotate about axis 776. Similarly, steering knuckle 706 and steering member 792 rotate relative to each other about central axis 711. Likewise, when the electric actuator 722 retracts (e.g., lever 726 retracts relative to body 724), the electric actuator 722 can rotate about axis 776, and steering knuckle 706 and steering member 792 rotate relative to each other about central axis 711. In this way, the extension and retraction of the electric actuator 722 can drive the rotation / pivot of steering knuckle 706 about axis 720 to rotate traction element 22. The electric actuator 722 can receive electricity from electrical storage device 40 for extension and retraction. The electric actuator 722 can receive control signals from controller 200 indicating the degree of extension or retraction (and thus the degree of rotation of traction element 22). The controller 200 may provide a control signal to the electric actuator 722, indicating the degree of extension or retraction, in response to user input received from the HMI 500 or any other user input device of the lifting device 10. The controller 200 operates the electric actuator 722 to extend or retract to indicate the direction of rotation of the lifting device 10.
[0169] The electric motor 24 can also receive electricity from the energy storage device 40 to drive the traction element 22. The electric motor 24 can receive control signals from the controller 200 to operate (e.g., at a desired speed).
[0170] The bow-shaped member 708 has a curved shape such that when the traction element 22 pivots to its angular limits (e.g., when the electric actuator 722 is fully extended, possibly the most rapid rotation, etc.), the steering member 792 does not contact the motor 24. This facilitates more rapid rotation of the lifting device 10 without the steering member 792 contacting the motor 24.
[0171] Specific reference Figure 30 The lifting device 10 may include a cover, protective device, planar member, etc., which is shown as a protective member 731. The protective member 731 may project outward from the lifting device 10 in the direction of travel of the lifting device 10. The protective member 731 provides a barrier against objects in front of the lifting device 10, preventing the electric actuator 722 from contacting the object when the lifting device 10 is driven. The lifting device 10 may include a front protective member 731 and a rear protective member 731 disposed at opposite ends of the lifting device 10. The protective member 731 may project outward along a longitudinal axis 778 in a forward direction 750 or a rearward direction. For example, the front protective member 731 may project outward from the front of the base assembly 12 in a forward direction 750. Similarly, the rear protective member 731 may project outward from the rear of the base assembly 12 in a rearward direction.
[0172] It should be noted that although only one traction element 22 is shown pivoting / rotating via the steering system 700, any or all of the traction elements 82 of the lifting device 10 can be similarly constructed. For example, the steering system 700 may include similar and symmetrical electric actuators 722 on opposite sides (e.g., left / right) of the base assembly 12, which steer the traction element 22 on the opposite sides. In some embodiments, the steering system 700 is positioned on the outward-facing side of the transverse frame member 710 (e.g., the forward-facing side of the front transverse frame member 710, the rearward-facing side of the rear transverse frame member 710). In other embodiments, the steering system 700 is positioned on the inward-facing side of the transverse frame member 710 (e.g., the inward-facing side of the front transverse frame member 710, the forward-facing side of the rear transverse frame member 710).
[0173] control system
[0174] Specific reference Figure 10 The control system 1000 for the lifting device 10 includes a controller 200, a turntable battery 802, a charger 804, a battery sensor 1004, a slip ring drive 812, a power inverter 810, a base assembly battery 806, a battery sensor 1002, a charger 808, a base assembly 12, and a lifting device 14. The controller 200 can represent any one or a combination of the following: base control module 412, turntable control module 428, traction controller 414, steering controller 416, base assembly controller 820, base battery management system 834, turntable battery management system 840, or turntable main controller 842. Any one of the functions of the base control module 412, turntable control module 428, traction controller 414, steering controller 416, base assembly controller 820, base battery management system 834, turntable battery management system 840, or turntable main controller 842 can be executed by the controller 200. In some embodiments, any of the functions of the controller 200 as described herein are distributed in or performed by a combination of the base control module 412, the turntable control module 428, the traction controller 414, the steering controller 416, the base assembly controller 820, the base battery management system 834, the turntable battery management system 840, or the turntable main controller 842.
[0175] The controller 200 includes processing circuitry 202, a processor 204, and a memory 206. Processing circuitry 202 can be communicatively connected to a communication interface, enabling processing circuitry 202 and its components to send and receive data via the communication interface. Processor 204 can be implemented as a general-purpose processor, an application-specific integrated circuit (ASIC), one or more field-programmable gate arrays (FPGAs), a set of processing units, or other suitable electronic processing units.
[0176] Memory 206 (e.g., memory, memory cell, storage device, etc.) may include one or more means (e.g., RAM, ROM, flash memory, hard disk storage, etc.) for storing data and / or computer code used to perform or facilitate the various processes, layers, and modules described herein. Memory 206 may be or include volatile or non-volatile memory. Memory 206 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described herein. According to some embodiments, memory 206 is communicatively connected to processor 204 via processing circuitry 202 and includes computer code for (e.g., by processing circuitry 202 and / or processor 204) performing one or more processes described herein.
[0177] The controller 200 is configured to generate control signals for the base assembly 12 and / or the lifting device 14 to perform a requested function input by the user input device 1006. For example, the user input device 1006 can be any button, handle, human-machine interface, touchscreen, steering wheel, etc., through which the user or operator of the lifting device 10 can provide user input. The controller 200 can receive user input and generate control signals for the base assembly 12, the lifting device 14, or various controllable elements (e.g., electric actuators, linear electric actuators, motors, etc.) to perform the requested function (e.g., steering operation, drive operation, lifting operation, turntable operation, etc.) of the base assembly 12 or the lifting device 14.
[0178] Controller 200 may receive sensor feedback from any system, subsystem, electrical device, etc., described herein via one or more sensors. Controller 200 receives battery charge of turntable battery 802 from battery sensor 1004 and battery charge of base assembly battery 806 from battery sensor 1002. Controller 200 may also generate and provide control signals for charger 808, power inverter 810, slip ring drive 812, or charger 804 to perform recharging operations as described in more detail above.
[0179] Charger 808 can be connected to a facility power source and can provide charging power to base assembly battery 806. Controller 200 can monitor the battery level of base assembly battery 806 and operate charger 808 to charge base assembly battery 806 to a desired level. Base assembly battery 806 can provide power to base assembly 12 or its various electrical components, enabling the electrical components of base assembly 12 to operate to perform their respective functions (e.g., drive and steering functions). In some embodiments, base assembly battery 806 provides power (e.g., AC power) to base assembly 12 or its various electrical components via power inverter 810.
[0180] The base assembly battery 806 can supply DC power to the power inverter 810. The power inverter 810 can supply AC power to the slip ring drive 812, such that AC power (e.g., provided by the charger 808 or from facility power) can be supplied to the turntable battery 802 to recharge the turntable battery 802 (e.g., via the charger 804). The controller 200 can generate control signals for the charger 804 and / or the slip ring drive 812 to transfer power from the power inverter 810 to the turntable battery 802, thereby recharging the turntable battery 802. In some embodiments, the controller 200 receives the battery charge of the turntable battery 802 from the battery sensor 1004 and operates the charger 804, the slip ring drive 812, and the power inverter 810 to charge the turntable battery 802 until the turntable battery 802 reaches at least a minimum charge level. The controller 200 can also generate control signals for the slip ring drive 812 to rotate the turntable assembly 800 relative to the base assembly 12 as requested by the user input (e.g., to perform turntable operation).
[0181] It should be understood that controller 200 may be configured to operate charger 808, power inverter 810, slip ring drive 812, and charger 804 to replenish or recharge turntable battery 802 when charger 808 is connected to facility power or when charger 808 is not connected to facility power. For example, if controller 200 detects that the battery charge obtained by battery sensor 1004 is below a threshold level, controller 200 may operate charger 808, power inverter 810, slip ring drive 812, and charger 804 to replenish turntable battery 802 using energy provided by base assembly battery 806.
[0182] The controller 200 can also limit the operation of the base assembly 12 and / or the lifting device 14 based on the connection status of the charger 808 to the facility power supply, the battery level of the turntable battery 802, and the battery level of the base assembly battery 806. For example, if the controller 200 detects that the turntable battery 802 has a battery level below a first threshold, the controller 200 may limit the operation of the lifting device 14 to raise the implement assembly 16 until the turntable battery 802 is replenished. If the battery level of the base assembly battery 806 is sufficient to recharge or replenish the turntable battery 802 and / or if the charger 808 is connected to the facility power supply, the controller 200 may use the recharging or replenishing techniques described herein to replenish the turntable battery 802. If the battery level of turntable battery 802 drops below a second threshold level, and controller 200 determines that charger 808 is still not connected to facility power and base assembly battery 806 does not have sufficient battery power to replenish turntable battery 802, controller 200 may restrict operation of base assembly 12 until charger is connected to facility power, and may operate the display device or notification system of lifting device 10 to prompt the operator to connect charger 808 to facility power for recharging. Controller 200 may similarly use the battery level of base assembly battery 806 to restrict operation of base assembly 12. Controller 200 may also cut off power to lifting device 10 (e.g. to base assembly 12 and / or lifting device 14 and / or turntable assembly 800) in response to a detected period of user inactivity to maintain or preserve the state of charge of base assembly battery 806 and / or turntable battery 802.
[0183] Specific reference Figure 25 The control system 1800 for the lifting device 10 includes a controller 200, an input device 1802, and a controllable element 1804. In some embodiments, the input device 1802 includes, but is not limited to, a drive and steering enable switch 186, a button 184, a joystick 188, an HMI 500, a joystick 190, and a handle rotation input device 194. Similarly, the controllable element 1804 may include, but is not limited to, linear actuators 38, 52, 30, 54, 42, 164, 302, and a motor 24. The controller 200 is configured to receive various input signals from the input device 1802 and generate control signals for any of the controllable elements 1804 of the lifting device 10.
[0184] In some embodiments, the controller 200 is wirelessly connected to the remote user device 208. The controller 200 can receive user input or requests from the remote user device 208 to deploy the deployable operator station 100. In response to receiving user input, the controller 200 can generate control signals for various controllable elements 1804 to deploy the deployable operator station 100. Advantageously, the remote user device 208 and the controller 200 can facilitate the initiation of the deployment of the deployable operator station 100 before the user or operator is at the lifting device 10 (e.g., away from the lifting device 10).
[0185] The controller 200 may also be configured to restrict, block, or disable one or more functions of the lifting device 10 in response to receiving an indication from the operator sensor 210 that the operator is not at the deployable operator station 100. The operator sensor 210 may be a camera, distance or proximity sensor, motion detector, temperature sensor, weight sensor, accelerometer, etc., or any other sensor capable of detecting the presence of an operator at the deployable operator station 100. In some examples, the controller 200 may function as a key that can be used to activate one or more motors within the lifting device 10. In some examples, such as... Figure 41 As shown, docking station 125 is located within deployable operator station 100. To activate lifting device 10, the user can first dock remote and mobile controller 200 to docking station 125. Connecting the handheld controller 200 to docking station 125 establishes a wired or other reliable connection to controller 200 to execute commands and transmit commands to various systems throughout lifting device 10. When the operator has finished operating the machine, the operator can remove controller 200. Controller 200 can then be charged separately off-site, for example, to limit the current drawn from energy storage device 40 located on lifting device 10. By removing controller 200 from deployable operator station 100, the operator can effectively remove the entire operating system of lifting device 10, which further prohibits unauthorized use of lifting device 10. Additional display elements can be provided to reflect feedback from cameras positioned around base assembly 12 of lifting device 10. These display elements can provide diagnostic or operational information that can assist the operator within deployable operator station 100 in performing desired tasks with lifting device 10.
[0186] Specific reference Figure 28 Another control system 600 for the lifting device 10 includes a controller 200, an input device 602, and a controllable element 604. The control system 600 may be the same as or similar to the control system 1000. For example, the control system 600 may include, for instance, […]. Figure 25Any of the input devices 1802 shown. In some embodiments, input devices 602 include, but are not limited to, operator station input device 602a and platform input device 602b. Similarly, controllable elements 604 may include, but are not limited to, linear actuators 38, 52, 30, 54, 42, electric motor 24, 722, turntable motor 64, and / or station actuators 606 configured to operate to at least partially deploy the deployable operator station 100. Controller 200 is configured to receive the respective input signals from input devices 602 and generate control signals for any controllable elements 604 of the lifting device 10.
[0187] In some embodiments, controller 200 is wirelessly connected to remote user device 208. Controller 200 can receive user input or requests from remote user device 208 to deploy the deployable operator station 100. In response to receiving user input, controller 200 can generate control signals for various controllable elements 604 (e.g., station actuator 606) to deploy the deployable operator station 100. Advantageously, remote user device 208 and controller 200 can facilitate initiating the deployment of the deployable operator station 100 before the user or operator is at the lifting device 10 (e.g., away from the lifting device 10). In some embodiments, controller 200 is configured to receive input signals from remote user device 208 to operate the lifting device 10 (e.g., drive or steer the lifting device 10). For example, if the lifting device 10 is configured as a MEWP, the operator can use remote user device 208 to operate the lifting device 10 from platform assembly 90 (e.g., operate lifting device 14, steering system 700, drive operation, steering operation, turntable assembly 800, etc.). When the operator is not at the operator station but on platform component 90, the operator can also control the hoisting device 10 via remote user device 208. When the hoisting device 10 is in MEWP mode, the operator can control or operate the hoisting device 10 via ground control and / or work platform control.
[0188] Still refer to Figure 28 The diagram illustrates a controllable element 604 that consumes or receives electrical energy from an energy storage device 40. The energy storage device 40 may use one or more split-cell battery technologies to ensure continuous rotation of the turntable assembly 800 and to help extend battery life or improve the energy consumption efficiency of the controllable element 604.
[0189] The controller 200 can operate the controllable element 604 according to various modes. For example, the controller 200 can operate the lifting device 10 in MEWP mode and MH mode. When the lifting device 10 is configured as an MEWP, the controller 200 can operate the motor 24 such that the functional performance and load-bearing capacity are maintained at or above that of a conventional MEWP that cannot be converted to MH. In MEWP mode, the controller 200 can allow lifting speeds typical for a conventional MEWP. However, the controller 200 can operate the motor 24 such that the lifting device 10 can travel or transport at twice the speed of a conventional MEWP. In some embodiments, when the lifting device 10 is in MEWP mode, the controller 200 keeps the deployable operator station in the deployed state or position.
[0190] The controller 200 can also switch the lifting device 10 to MH mode after the platform assembly 90 has been replaced by the fork 18, material handling assembly, glass clamp, platform configured to support materials or additional loads, or any other implement. The controller 200 can operate the controllable element 604 to deploy the deployable operator station 100 in MH mode. This allows the operator to sit at the deployable operator station 100 and operate the lifting device 10. In some embodiments, the drive speed achievable by the lifting device 10 in MH mode is 2-3 times greater than the maximum speed achievable by the lifting device 10 in MEWP mode. When the controller 200 operates the lifting device 10 according to MH mode, the lifting speed of the lifting device 14 can be the same as or similar to that of a conventional material handling machine. Advantageously, the lifting device 10 can have a greater load capacity than a conventional MH in MH mode. Advantageously, the deployable operator station 100 can be deployed or folded / retracted to improve visibility. In addition, the deployable operator station 100 provides additional or improved visibility compared to other telescopic forklifts that use conventional cabs.
[0191] The controller 200 may also be configured to restrict, block, or disable one or more functions of the lifting device 10 in response to an indication received from the operator sensor 210 that the operator is not at the deployable operator station 100. For example... Figure 2 As shown, operator sensor 210 can be located at deployable operator station 100 (e.g., at seat 124). Operator sensor 210 can be a camera, distance or proximity sensor, motion detector, temperature sensor, weight sensor, accelerometer, etc., or any other sensor capable of detecting the presence of an operator at deployable operator station 100.
[0192] Reference Figure 10 , Figure 25 and Figure 28Any of the control systems 1000, 1800, or 600 that can be implemented on the lifting device 10 may include a movable control box 1008. The movable control box 1008 may be a component of the lifting device 10. The movable control box 1008 may be configured to communicate wirelessly or wiredly with the controller 200. For example, the movable control box 1008 may be communicatively connected to the controller 200 via a wire or plug at a deployable operator station 100 (e.g., at HMI 500), a fixed operator station of the lifting device 10, platform assembly 90, or implement assembly 16. The movable control box 1008 may be removed from its plug and wiredly disconnected, and moved to another location on the lifting device 10 where it may be communicatively connected to a different plug. For example, the movable control box 1008 may be wiredly connected to a plug or quick-disconnect device at the deployable operator station 100 or at the implement assembly 16 (e.g., if the implement assembly 16 is configured as platform assembly 90).
[0193] The movable control box 1008 may include various switches, buttons, handles, joysticks, etc., to provide user input to the controller 200. The movable control box 1008 may provide user input to the controller 200 to operate the lifting device 10 (e.g., drive or manipulate the lifting device 10 or operate the lifting equipment 14). The platform assembly 90 or the deployable operator station 100 may include a container for storing the movable control box 1008. For example, the deployable operator station 100 may include a container (or other storage device) for storing the movable control box 1008, such that the movable control box 1008 can be protected and secured when the deployable operator station 100 is switched to a folded or stowed position.
[0194] Advanced site control
[0195] Reference Figures 46 to 58The lifting device 10 can be used to perform various types of tasks at the construction site 2000, including autonomous, semi-autonomous, and manual tasks that can be performed by an operator physically within or remotely from the lifting device 10. The construction site 2000 may include various equipment, including the lifting device 10 and other MEWPs, as well as material handling vehicles 2002, which can be remotely monitored and controlled using a series of cameras and controllers located throughout the construction site 2000. Cameras may be positioned on the lifting device 10, MEWPs, material handling vehicles 2002, and one or more drones 2004, which can monitor the construction site 2000 from the air. Various vehicles and equipment at the construction site 2000 can be centrally controlled or monitored via mobile devices (e.g., mobile phones, tablets, computers, etc.). In some examples, several mobile devices can simultaneously monitor and / or control different equipment at the construction site 2000 using camera lenses from different cameras at the construction site and operational information received from equipment or drones 2004. In some examples, individual cameras located throughout the construction site can record activities on the construction site 2000. In some examples, drones 2004 and / or other equipment can monitor environmental characteristics present at the site 2000, such as noise and pollution.
[0196] Now refer to Figures 47 to 49 The image depicts an operator using a controller 2006 to remotely control a material handling vehicle 2002. The controller 2006 can be used to monitor and / or control various equipment throughout the site 2000; the controller 2006 may be part of or integrated into a handheld mobile device 2008 (e.g., a mobile phone, tablet, laptop, etc.). In some examples, and as... Figures 48 to 49 As shown, the handheld mobile device 2008 includes a graphical user interface (GUI) 2010 that can display various datasets related to the construction site 2000. The datasets may include, for example, machine performance or health status, and may also include real-time data feedback (performance parameters, camera views, etc.) from one or more lifting devices 10, MEWP 2002, or drones 2004 located throughout the construction site 2000.
[0197] In some examples, controller 2006 can be used to regulate the status of one or more lifting devices 10, MEWP 2002, or drones 2004 on site 2000. For example, as Figure 48As shown, controller 2006 can be used to switch between various operating modes of equipment at site 2000. In some embodiments, the different operating modes may include levels of autonomy. Using controller 2006, a user can switch a piece of equipment at site 2000 between manual operating mode (e.g., when a person is physically present within the device, a person provides drive and lifting commands), remote manual operating mode (e.g., an operator provides drive and lifting commands remotely via controller 2006 or other systems), semi-autonomous operating mode (the user controls the vehicle's movement, but the implement components operate autonomously), and fully autonomous operating mode. In some examples, when the equipment is in remote manual mode and / or semi-autonomous operating mode, commands can be wirelessly provided to the equipment using controller 2006. Thus, an operator can use controller 2006 to control the position and / or operation of a piece of equipment without needing to be physically present within lifting device 10, MEWP 2002, or drone 2004. In other examples, controller 2006 acts as a key that unlocks the equipment to move in manual operating mode when the equipment detects the controller's physical presence within deployable operator station 100.
[0198] Different operating modes selectable by the user can also be defined by the desired tasks to be performed by the lifting device 10, MEWP 2002, or UAV 2004 or other equipment types. For example, the operator can select the lifting device 10, which provides multiple available tasks and / or modes that can be performed by the lifting device 10. In some examples, different modes may include a material handling mode and an aerial work platform (AWP) mode. Depending on the user's selection of the mode (e.g., using controller 2006 and / or GUI 2010), the lifting device 10 can determine whether it first needs to reconfigure its implement assembly 16. If the material handling mode is selected, the lifting device 10 (e.g., using controller 200) or controller 2006 will first determine whether the appropriate implement is currently attached to the lifting device 14. If the lifting device 10 or controller 2006 detects that the platform assembly 90 is attached to the lifting device 14 (e.g., opposite the fork 18), the lifting device 10 may first travel to a nearby location to perform an implement change operation. The platform assembly 90 may be disengaged from the lifting device 14, and the fork 18 may be engaged by the lifting device 14. By attaching the fork 18 to the lifting device 10, the material handling mode can be enabled. Conversely, if the AWP mode is selected, the lifting device 10 and / or the controller 2006 will determine whether the appropriate platform component 90 is connected to the lifting device 14, and will automatically perform a changeover operation if a switch from the material handling mode back to the AWP mode is required.
[0199] like Figures 48 to 49As shown, the GUI 2010 on the handheld mobile device 2008 may include a split configuration that provides real-time media (e.g., images, videos, etc.) captured from one or more cameras positioned on the equipment, and provides controls that can be used to guide and / or drive the lifting device 10 or other equipment. In some examples, the GUI 2010 is configured to provide a forward-facing view 2012 from the cameras positioned on the lifting device 10, and provides one or more virtual joysticks 2014 or pads that allow the operator to perform different drive, steering, lifting, or tilting operations. Thus, the operator can control the prime mover and lifting device 14 using the handheld mobile device 2008 and the GUI 2010. In some examples, the GUI 2010 also includes a mode selection actuator 2016. As described above, tapping the mode selection actuator 2016 switches the lifting device 10 (or other selected equipment) between various operating modes.
[0200] Reference Figure 50 Various pieces of equipment (including the lifting device 10 and MEWP 2002 at site 2000) can be electrically powered. Therefore, over time, the energy storage devices 40 on the various pieces of equipment will consume energy and need to be recharged. Site 2000 may include a charging station 2018 capable of rapidly and autonomously recharging the various pieces of equipment. The charging station 2018 includes several solar panels 2020, which can be configured to harvest and store energy from sunlight. The harvested energy can be transmitted via wired or wireless connections to one or more lifting devices 10 or MEWP 2002 located below or near the charging station 2018. In some examples, the charging station 2018 includes one or more charging cables 2022, which can be inserted into a piece of equipment to initiate a charging operation. An operator can be assigned to the charging station to perform a physical insertion process to connect equipment to the charging station 2018 using the charging cables 2022.
[0201] Reference Figures 51 to 52 and Figures 55 to 57The lifting device 10 and / or MEWP 2002 may be arranged to perform tasks using targeted projection to guide the lifting device 10 and / or MEWP 2002 at various locations on site 2000. In some examples, a mobile device (e.g., a handheld mobile device 2008 or another mobile device) may be used to provide a target projection 2024 onto an area (such as an elevated surface). The mobile device projects the target 2024 onto the surface, which can then be identified and used by the controller 200 of the lifting device 10 to position the tool assembly 16 until the tool assembly 16 reaches the projected target 2024. In some examples, a drone 2004 may provide the target projection 2024. Thus, an operator may use the controller 2006 to select a target area. With the target selected, the drone 2004 may fly to the target area and then project the target 2024 onto the selected area below. The controller 200 may then position the lifting device 10 such that the tool assembly 16 is located within the projected target 2024. Once the implement assembly 16 reaches the target area 2024 (which can be accomplished using sensor feedback, optical sensors, etc.), the implement assembly 16 can unload materials or hold the operator at the target location until the task is completed, such as... Figure 52 As shown. In some examples, such as Figure 57 As shown, the UAV 2004 also includes a camera to monitor the lifting device 10 as the load on the implement assembly 16 moves toward the target 2024.
[0202] Reference Figures 53 to 54 The controller 2006 and / or drone 2004 can be used to perform tool or equipment transport operations. Using a mobile phone or other mobile device (e.g., handheld mobile device 2008), a worker on the lifting unit 10 or MEWP 2002 can select from a catalog of different tools that may be needed to perform a task when the tool is lifted onto the work platform assembly 90. The worker can scroll through a library of different available tools and then select a tool on the mobile device. When the drone 2004 receives communication that the worker has selected one or more tools, the drone 2004 receives instructions (e.g., from the central controller 2006) to retrieve the selected tool and bring it to the worker at the location where the tool was requested.
[0203] Now refer to Figures 58 to 59The lifting device 10 is depicted with different robotic tooling assemblies 2030, 2032, which can be used to perform a variety of different tasks at height. The robotic tooling assemblies 2030, 2032 may include one or more articulated fingers 2034 and others, which can be manipulated to perform various tasks, including positioning material. The robotic tooling assemblies 2030, 2032 have multi-axis positioning, which allows material to be manipulated and positioned to a desired location, which is particularly useful in construction processes. For example, the first lifting device 10a can be used as a positioner, while the second lifting device 10b can be used as a welding machine. The positioner may include a three-finger assembly 2036. The three-finger assembly 2036 may include one or more material interfaces 2038 positioned at the distal end of each finger 2034. In some examples, the material interface 2038 is a vacuum chamber that can generate a low-pressure suction force sufficient to selectively attach material to the robotic tooling assembly 2030. The resulting suction allows the robotic tooling assembly 2030 to lift and suspend heavy materials from the ground, enabling the performance of various tasks (e.g., welding, fastening, etc.). Once the material has been correctly positioned and / or attached to the desired location, the vacuum can be released, separating the robotic tooling assembly 2030 from the material. Various other types of material interfaces 2038 can also be used, including movable grippers capable of grasping and securing objects. In some examples, the fingers 2034 of the three-finger assembly 2036 are configured to extend and retract, allowing the three-finger assembly 2036 to accommodate objects of varying sizes.
[0204] The robotic tooling assembly 2032 is configured as a welding machine and includes a welding electrode 2040 located at its distal end. The tooling assembly 2032 is again configured with articulated fingers 2034, which are configured to move about multiple axes to perform welding. In some examples, the tooling assembly 2032 includes a built-in welding wire supply, fed via a supply tube 2042 within the tooling assembly 2032. The position of the welding electrode 2040 can be controlled simultaneously by both the robotic tooling assembly 2032 and the lifting device 14. In some examples, the controller 200 is configured to perform the welding operation. The robotic tooling assemblies 2030 and 2032 can be interchangeable, such that the first lifting device 10a can also be a welding machine if different robotic tooling assemblies 2032 are attached.
[0205] like Figure 58As shown, the lifting devices 10a, 10b and the tooling assemblies 2030, 2032 can also be remotely controlled to perform various tasks. For example, using a handheld mobile device 2008 (which may include a controller 2006), an operator can guide one or more lifting devices 10a, 10b without physically being present within any of them. A camera can be mounted on one or both of the tooling assemblies 2030, 2032 to monitor the process performed by the tooling assemblies 2030, 2032 and provide real-time feedback on that process. If the lifting devices 10a, 10b are in fully autonomous mode, the handheld mobile device 2008 can be used as a mechanism for monitoring the operational progress. The handheld mobile device 2008 can be used to input different parameters that can be executed by the robotic tooling assemblies 2030, 2032. For example, the operator can input a specific welding dimension call that will be automatically performed by the robotic tooling assembly 2032. In some examples, a handheld mobile device 2008 and a controller 2006 are typically used to control robotic implement assemblies 2030, 2032 from the ground below. Using a GUI 2010 and a virtual joystick 2014, an operator can guide the robotic articulated fingers 2034 of each implement assembly 2030, 2032 to perform different tasks (e.g., positioning, welding, etc.) at height. Using camera feedback and semi-autonomous or fully autonomous control, workers can perform tasks that might otherwise be difficult to accomplish without leaving the ground. In some examples, additional cameras mounted to the drone 2004 or other locations within the site 2000 can be accessed by the handheld mobile device 2008 to provide additional angles and views that can assist implement assemblies 2030, 2032 in performing desired tasks. The GUI 2010 and / or handheld mobile device 2008 communicate with these remote and autonomous, semi-autonomous, or automated robotic implements 2030, 2032 and can provide partial or full control over these remote and autonomous, semi-autonomous, or automated robotic implements 2030, 2032, thereby enabling the completion of tasks. Although described as a handheld mobile device 2008, various tasks may also be assigned to or otherwise instructed by a central computer system located at site 2000 or connected to various devices at site 2000 via the Internet or other communication protocols. The robotic implements 2030, 2032 are configured to communicate wirelessly with controller 200 or via a wired connection established via lifting device 14. In some examples, the robotic implements 2030, 2032 include wireless transceivers configured to receive commands from controller 2006 via controller 200, which can provide bidirectional data streaming. Although displayed as a location and welding machine, various types of robot tooling components 2030 and 2032 can be used. For example, a lifting hammer attachment, a nail gun attachment, etc., can be used.In some examples, the robotic implement assembly may include or be connected to a pressurized water source and may be used to perform a window cleaning process. In other examples, the robotic implement assembly may be configured as a paint nozzle. In each example, the implement assembly may be configured to operate automatically or autonomously, or may be configured to operate according to control commands received from a remote controller 2006 (e.g., via a handheld mobile device 2008), which may at least partially eliminate the need to position workers at heights to perform the task. In some examples, the robotic implement assemblies are configured with their own internal control systems such that control commands issued by controller 2006 are transmitted directly to the robotic implement assembly, rather than through controller 200.
