Description

Technical Field

[0001] This invention relates to the field of equipment that can be detachably placed in or on a dedicated location on a machine by a forklift. Regarding the machine, the invention relates more specifically to, but is not limited to, mobile lifting work platforms (MEWPs), also known as aerial work platforms (AWPs). Regarding the equipment, the invention relates more specifically to generators. Background Technology

[0002] Aerial work platforms are machines designed to allow one or more people to work at heights. For this purpose, they consist of a work platform for use by one or more people. The work platform is supported by a lifting mechanism that can raise it from a lower position on the frame of the aerial work platform to the desired working position at a certain height. The lifting mechanism is typically operated by a hydraulic circuit.

[0003] There are self-propelled aerial work platforms specifically designed for all-terrain outdoor use. They operate on construction sites or other outdoor locations where there is often no or only limited power supply. Therefore, they are typically powered by an internal combustion engine and equipped with a fuel tank to ensure acceptable operational autonomy, allowing for on-site refueling if necessary. The internal combustion engine drives one or more hydraulic pumps in a hydraulic circuit that operates the lifting mechanism of the work platform and powers a hydraulic motor that drives the platform's wheels for movement on the ground.

[0004] The disadvantages of this type of aerial work platform are environmental pollution caused by the exhaust gas from the internal combustion engine and noise pollution caused by the noise from the engine itself.

[0005] Another drawback of this type of aerial work platform is that they cannot be used inside buildings, precisely because of the exhaust fumes and noise from the internal combustion engine.

[0006] In contrast, there are electric aerial work platforms specifically developed for use inside buildings. The power for various movements is provided by one or more electric motors powered by rechargeable batteries. Specifically, each wheel of the aerial work platform is equipped with an electric motor for ground movement, and another electric motor is dedicated to operating the hydraulic pump in the hydraulic circuit used to operate the lifting mechanism of the work platform. Therefore, these aerial work platforms are environmentally friendly and quiet. The aerial work platforms are also equipped with single-phase chargers for charging the batteries by connecting to a single-phase power source. Battery charging is typically carried out at night, so the aerial work platform can be used the next day and has at least one workday of autonomy.

[0007] However, these electric aerial work platforms are not designed for all-terrain outdoor use. In fact, they are unsuitable for overcoming obstacles, especially given their low ground clearance, insufficient power of the electric motors driving the wheels, and the position of these motors that exposes them to impacts in all-terrain environments. Due to their wheelbase and lack of stabilizing outriggers, they are also not designed to provide sufficient stability outdoors, for example, on uneven terrain. Furthermore, their autonomy is insufficient, as aerial work platforms designed for all-terrain outdoor use consume more energy, particularly since they require more powerful motors to overcome obstacles, and also have auxiliary devices such as stabilizing outriggers that need to be operated. This is even more true when their workplace lacks or has limited access to a power grid and cannot be adequately charged.

[0008] More commonly, there exists a technological bias that posits electric aerial work platforms without internal combustion engines are unsuitable for all-terrain outdoor use. This bias stems primarily from their lack of operational autonomy, considering the size of the rechargeable batteries that can be mounted on the platform, their increased power demands, the variable environmental conditions (especially temperature), which are detrimental to the batteries, and the inability to adequately access a power grid for charging. This bias is further exacerbated in the case of scissor lifts, which are often stationed at designated points on construction sites for extended periods, sometimes a day or more. Charging the batteries of a mobile aerial work platform requires relocating it to the same location, representing a waste of time and effort for the user.

[0009] Recently, hybrid motorized aerial work platforms, which combine an electric motor and an internal combustion engine, have been proposed. This type of aerial work platform can use an electric motor indoors and an internal combustion engine outdoors. In some cases, the two motors can be coupled in series to provide power for lifting. An example of such an aerial work platform is disclosed in EP 1 967 486 A1. However, these hybrid aerial work platforms also suffer from the disadvantages of environmental and noise pollution sources associated with internal combustion engines. Summary of the Invention

[0010] Therefore, the applicant has set out to pursue the objective of providing an aerial work platform that substantially limits the aforementioned disadvantages. In particular, one objective is to propose an aerial work platform that can be used outdoors in all terrains while significantly limiting environmental and noise pollution. To this end, the applicant has proposed an aerial work platform suitable for outdoor use in all terrains in its patent application FR 3092101A1, comprising:

[0011] - A frame equipped with at least two front wheels and at least two rear wheels, allowing the aerial work platform to move along the ground.

[0012] -Work platform,

[0013] - The lifting mechanism for the work platform, mounted on the frame.

[0014] - At least one first electric motor is used to provide driving force to move the aerial work platform along the ground.

[0015] - At least one second electric motor is used to provide driving force to operate the lifting mechanism of the work platform.

[0016] - At least one rechargeable battery for powering at least one first electric motor and at least one second electric motor.

[0017] in:

[0018] - The driving force for moving the aerial work platform along the ground is always provided by only one first electric motor, and

[0019] - The driving force for the lifting mechanism used to actuate the work platform is always provided by at least one second electric motor.

[0020] Aerial work platforms also include:

[0021] - A front axle equipped with two front wheels and a rear axle equipped with two rear wheels, wherein at least one of the axles is a drive shaft for transmitting the driving force of at least one first electric motor to the corresponding wheel.

[0022] - At least one single-phase charger for charging at least one rechargeable battery via connection to a single-phase power supply network; and

[0023] - Location for mounting (preferably in a detachable manner) a generator, which is intended to be connected to at least one of the chargers to recharge the battery.

[0024] This makes the aerial work platform more environmentally friendly and quieter, as it uses only an electric motor to provide the driving force needed to move the platform along the ground and operate the lifting mechanism. Therefore, the aerial work platform can be used not only outdoors but also indoors. Furthermore, electric motors are more energy-efficient than internal combustion engines and do not carry the risk of hydraulic fluid leakage like hydraulic motors. The wheels of the aerial work platform are mounted on the front and rear axles, allowing it to be used outdoors in all terrains. Given their robustness and reliability, and the fact that the first electric motor is not placed at the level of the wheels, the power provided by the first electric motor is appropriately selected. If, during use, the autonomy of the battery proves insufficient in the absence of a suitable power network, a generator can be installed at a designated location on the aerial work platform to recharge the rechargeable battery, thereby increasing the autonomy of the aerial work platform. More generally, the advantageous selection of its electrical and other components to reduce energy consumption can also be achieved through optimization of the control electronics on the aerial work platform. Therefore, this invention overcomes the technical prejudice that it is impossible to develop an electric aerial work platform without an internal combustion engine for outdoor use.

[0025] Preferably, the generator's installation on the aerial work platform is detachable, and the location of the aerial work platform itself for receiving it is preferably arranged to facilitate its installation and removal. Therefore, the generator can be installed on or removed from the aerial work platform as needed, particularly by the end user (e.g., on a construction site) or by an aerial work platform rental company (e.g., at the request of its customers). This detachable installation of the generator on the aerial work platform has several advantages. Therefore, it is possible to sell aerial work platforms without generators if the user only considers uses where the autonomy of their battery is sufficient, such as only for indoor or outdoor use with permanent or near-permanent power grid access. Furthermore, the generator can be added to the aerial work platform at any time if it is to be used later in an environment without sufficient external power. Additionally, this allows the same generator to be shared among multiple aerial work platforms designed to receive it in a detachable manner. For example, a rental company can manage a group of aerial work platforms using a smaller number of generators and provide them as accessories to customers who need them. Another advantage is that the generator's periodic maintenance is independent of the aerial work platform, during which time the aerial work platform can still operate. Another advantage is that the generator can also be removed from the aerial work platform for other uses on the construction site.

[0026] In the context of the aerial work platform proposed in this way, and more generally in the context of electric aerial work platforms that can be equipped with detachable generators, the applicant expects to provide a solution that allows the generator to be installed quickly and easily on the aerial work platform.

[0027] US 6,012,544 discloses a solution for detachably mounting a generator on an aerial work platform. It includes a support plate for the generator with two hooks, which suspend the support plate from the frame by inserting the hooks into two corresponding slots in the frame. The disadvantages of this solution are that mounting the generator on the frame is fragile because the hooks must be precisely aligned with the slots in the frame during installation, and the generator is generally heavy, exceeding 100 kg, and is typically moved by a forklift. Furthermore, there is a risk that the hooks may detach from the frame slots, for example, when the aerial work platform is moved on uneven ground.

[0028] To at least partially alleviate these drawbacks, the applicant provided an improved solution in its patent application FR 3 102 472 A1 for detachably placing a generator on an aerial work platform.

[0029] In the context of industrial trucks, DE 10 2012 106 215 A1 discloses a support structure for a power supply unit, which is detachably mounted in the receiving space of a forklift via another industrial truck. The support structure has multiple insertion channels for the fork teeth of the forklift. The support structure is provided with a locking device to prevent sliding of the support structure in the receiving space. The locking device includes two locking levers, each pivoting about its respective axis, and each locking lever is provided with a pin configured to engage a corresponding notch arranged in a support beam fixedly disposed in the receiving space of the forklift. Each locking lever is actuated by a respective actuating lever pivoting about its own axis, the cooperation between the actuating lever and the locking lever being achieved by the pin engagement of the latter into a guide groove of the former. The actuating lever is biased by a torsion spring to push the locking member into the locked position. Each actuating lever is provided with a plate extending into a corresponding one of the insertion channels for the fork teeth of the industrial truck. When the forks are inserted into the channel, they act on the plate of the actuator rod, which pivots and drives the locking lever to the release position.

[0030] However, this locking device is somewhat complex because the actuating rod and locking rod are separate components, and a pin is mounted on the actuating rod. Furthermore, the pivot axis of the locking rod and actuating rod is vertical, while the support structure has a guide rail with an L-shaped cross-section that engages a flange fixedly arranged below a support beam in the forklift's receiving space. Therefore, when placing the support structure with the power unit into the receiving space using a forklift, the height of the support structure must be precisely adjusted relative to the receiving space before insertion, which may be difficult for the forklift operator to see. The support structure with the power unit must then be moved in a purely horizontal manner to be inserted by sliding it horizontally into the receiving space. Moreover, when the forks of the industrial truck are withdrawn from the insertion channel, the support structure may slide out of the receiving space because the locking rod is in the released position until the forks are withdrawn, thus the locking device is not in the locked position. Therefore, this locking device is unreliable, and the operation of placing the support structure with the power unit into the forklift's receiving space is delicate.

[0031] The object of this invention is to provide further improvements that enable generators to be quickly and easily placed on aerial work platforms, or more generally, to be quickly and easily placed in or on any equipment that can be detachably placed by a forklift in or on a machine provided for this purpose. Another object of this invention is to provide a solution for reliably holding such equipment in or on a location provided for this purpose.

[0032] Therefore, according to a first aspect, the present invention provides an apparatus configured to be detachably placed in or on a dedicated location on a machine by a forklift, the apparatus comprising:

[0033] - Channels for the fork tines of a forklift, enabling the forklift to grab and transport equipment, and

[0034] - A locking system used to selectively lock the equipment in or on a designated position on the machine.

[0035] The locking system includes:

[0036] - At least one locking member that is movable between the following positions:

[0037] In the locking position, when the device is in or above the machine's designated position, the locking member engages with the machine's designated position retaining member.

[0038] The unlocked position disengages the locking component from the retaining component, allowing the device to be placed and removed from a designated location on or within the machine.

[0039] - At least one actuating member, which extends at least partially into a channel for the fork teeth of the forklift, so as to be actuated by the fork teeth of the forklift when the fork teeth of the forklift are inserted into the fork tooth channel.

[0040] And among them:

[0041] - When the equipment is oriented according to its orientation in or above the machine's designated position, the locking member is elastically biased toward the locking position and / or gravitationally biased toward the locking direction, and

[0042] - The actuating member and the locking member cooperate to move the locking member to the unlocked position when actuated by the fork of the fork.

[0043] In a preferred embodiment, the locking member is pivotally mounted about a horizontal axis with reference to the orientation of the device when it is in or above the machine's designated position. Advantageously, this allows the device to be placed in the machine's designated position by first moving it horizontally above the receiving position from any height above the receiving position. At this point, the retaining member in the designated position may not be able to reach the device's locking system. The placement operation is then completed simply by lowering the device into or above the machine's designated position. As soon as the forklift forks are retracted, the locking system cooperates with the retaining member to move into the locked position. This facilitates placing the device in the designated position because, compared to solutions disclosed, for example, DE 10 2012106 215A1, it is not necessary to adjust the device's height relative to the designated position before horizontal movement toward the designated position. Performing the above operations by reversing the order and direction also facilitates removing the device from the designated position.

[0051] - In the latter case, with reference to the orientation of the device when it is located in or on the machine's designated position, the first axis preferably extends horizontally, and with reference to the orientation of the device when it is located in or on the machine's designated position, the second axis preferably also extends horizontally; furthermore, the first and second axes preferably extend parallel to each other, which helps to realize the action of the actuating member on the locking member;

[0052] - The locking system includes at least two locking members that cooperate with a common or separate actuating member, each of the two locking members being configured to engage a common or separate retaining member of the machine from the opposite side in a dedicated position.

[0053] - In the latter case, it can be set to

[0143] Figure 28 An embodiment of a screw is shown, which is locked to a generator for securing the generator in a designated position on an aerial work platform, and the screw is in an untightened state.

[0144] Figure 29 Is with Figure 28 Same diagram, but the locking screws have been tightened. Detailed Implementation

[0145] The aerial work platform illustrated includes a frame 1, a lifting mechanism 2 mounted on the frame 1, and a work platform 3 supported by the lifting mechanism 2. The work platform 3 typically includes a floor and guardrails and is designed to accommodate vehicle-mounted personnel, and may also include equipment.

[0146] The aerial work platform is a scissor lift. In other words, the lifting mechanism 2 is a scissor lift mechanism: this type of lifting mechanism is known in itself. It consists of beams hinged at their center in a scissor-like manner, these scissor mechanisms being mounted on top of each other via their ends, which are pivotally connected so that they can be folded and unfolded at a height. One or more hydraulic cylinders 4 are used to extend or retract the lifting mechanism 2 to raise the work platform 3 to the desired working height and lower it onto the frame 1.

[0147] Frame 1 is equipped with at least two front wheels 10 and at least two rear wheels 11. These wheels allow frame 1 to stop on the ground and enable the aerial work platform to move along the ground. As shown in the diagram, the front side of the aerial work platform is designated AV, the rear side is designated AR, the left side is designated G, and the right side is designated D.

[0148] from Figure 4 As can be seen, the front wheel 10 is mounted on the front axle 12, and the rear wheel 11 is mounted on the rear axle 13. Advantageously, all wheels 10 and 11 are driven, thus the aerial work platform is equipped with all-wheel drive. In other words, the front axle 12 and the rear axle 13 are drive axles, and both are connected to the same electric motor M1 to drive their respective wheels. Conventionally, a reducer 16 can be provided to transmit the rotation of the output shaft of the electric motor M1 to the front axle 12 and the rear axle 13. Of course, reduction can also be achieved at the differential of each axle 12, 13 and / or at the connection of the wheels 10, 11. Preferably, each axle 12, 13 typically includes a differential that allows the corresponding wheels to rotate at different speeds. In this case, the motor M1 is mounted on one of the axles, and its rotational motion is transmitted to the other axle via drive shafts 14 connected at both ends by their respective universal joints 17. The central differential 15 preferably provides for distributing force between the front and rear axles and allowing different drive speeds between the two axles.

[0149] In this configuration, the front wheel 10 is steered, but alternatively, the rear wheel 11 may also be steered. In another embodiment, all four wheels 10, 11 are steered.

[0150] The use of four-wheel drive is particularly suitable for all-terrain outdoor use of aerial work platforms, especially for overcoming obstacles. Furthermore, using all-wheel drive is economical because only one electric motor is needed to drive the front and rear wheels. In addition, the front axle 12, rear axle 13, electric motor M1, drive shaft 14, and other related components can be advantageously pre-assembled into sub-assemblies ready for mounting on the frame 1, thus saving time during the assembly of the aerial work platform and simplifying the assembly process.

[0151] Alternatively, two electric motors M1 can be provided, one dedicated to driving the front wheel 10 and the other dedicated to driving the rear wheel 11. In this case, each of the two electric motors can be directly mounted on the corresponding drive shaft. However, using a single electric motor M1 to drive the wheels is more economical.

[0152] In another embodiment, the aerial work platform has only two drive wheels, either front or rear, driven by an electric motor M1.

[0153] Electric motor M1 is preferably dedicated to driving the wheels. The same applies if multiple electric motors M1 are used to drive the wheels.

[0154] Generally speaking, the fact that aerial work platforms are equipped with a front axle 12 and a rear axle 13 makes them suitable for all-terrain outdoor use, especially by providing adequate ground clearance without being hindered by the location of the electric motor. More generally, the mechanical design of aerial work platforms is suitable for all-terrain outdoor use and is similar to existing aerial work platforms designed for this purpose, particularly in terms of wheelbase and mechanical strength.

[0155] Figure 4 This is a schematic diagram of the electrical and hydraulic circuitry for an aerial work platform. As shown, the aerial work platform includes a battery 20 for powering its various electrical components. Alternatively, the aerial work platform may include multiple batteries connected in series and / or parallel; this variant is referred to hereinafter as a single battery 20. Preferably, the battery is provided to ensure that the aerial work platform has operational autonomy for at least one normal working day.

[0156] The aerial work platform includes at least one first single-phase charger 31 for charging the battery 20 via a battery management circuit 21. It is preferably configured to accept AC voltage as input, corresponding to the single-phase mains voltage used in the country where the aerial work platform is located.

[0157] As a reminder, in Europe, single-phase mains voltage is generally 230VAC 50Hz. In many countries around the world, it ranges from 220VAC to 240VAC, typically 50Hz, sometimes 60Hz. In many countries in the Americas and many more, single-phase mains voltage is 110VAC to 127VAC, typically 60Hz, sometimes 50Hz. In Japan, depending on the region, it is 100VAC, 60Hz, or 50Hz.

[0158] Therefore, charger 31 can be advantageously designed for single-phase mains voltage ranges to suit different countries, such as from 110VAC to 230VAC or even 100VAC to 240VAC.

[0159] The aerial work platform may include two additional single-phase chargers 32 and 33, which, together with the first charger 31, charge the battery 20 from the three-phase mains power via the battery management circuit 21.

[0160] Therefore, the aerial work platform should be equipped with a cable fitted with a standard plug 34 or a standard socket or any other suitable device for connecting one of the single-phase chargers 31 to 33 to a standard single-phase socket on the national power grid. It is also equipped with a second cable fitted with a standard plug 35 or a standard socket or any other suitable device to enable the aerial work platform to connect to a standard three-phase socket on a three-phase power grid.

[0161] This is advantageous when the maximum current provided by a standard single-phase AC outlet is incompatible with the fast charging capability of battery 20. This is typically the case with most 220VAC or 230VAC single-phase AC networks, where the standard plug is designed to provide a maximum current of 16A. A three-phase power supply network allows battery 20 to charge much faster than a single-phase network because the maximum power that can be provided simultaneously by three phases is greater than that by a single phase, and the output power of chargers 31 to 33 is added together.

[0162] From this perspective, each of the chargers 31, 32, and 33 is preferably designed to accept a single-phase voltage of at least 220VAC or 230VAC as input. Therefore, the battery 20 can be charged by connecting the first charger 31 to a single-phase AC power supply of the corresponding voltage—or another voltage that it can accept as input—or by connecting the three chargers 31, 32, and 33 to a 380VAC or 400VAC three-phase AC power supply, with each charger connected between its corresponding phase and neutral line to receive a 220VAC or 230VAC input voltage.

[0163] Chargers 32 and 33 may be designed for single-phase voltages of 220VAC or 230VAC, while the first charger 31 may be designed for the voltage range described above. Alternatively, the three chargers 31, 32, and 33 may be identical and provide the voltage range mentioned for the first charger 31.

[0164] Advantageously, chargers 31 to 33 can charge the battery to 80% of its capacity in less than 3 hours, or even less than 2.5 hours, preferably within 2 hours, provided that the three-phase power supply network to which they are connected can provide the required power. In contrast, charging the battery to 80% using a single-phase charger takes approximately 6 to 8 hours. Battery 20 can also be charged via two-phase charging by using an aerial work platform equipped with, or only with, two of the three chargers 31 to 33. Preferably, the aerial work platform is designed with three positions for mounting one of chargers 31, 32, and 33. Therefore, the same aerial work platform can be equipped with one to three chargers 31, 32, and 33 as needed.

[0165] The onboard electronics 70 is preferably designed to adjust the charging curve of the battery 20 according to the availability of the relevant national power grid and whether it is a single-phase or three-phase power grid. For this purpose, the operator is instructed to provide the national grid information to the onboard electronics 70 via a control panel 75. The aerial work platform is designed to have a detachably mounted generator 40. The generator 40 is intended to charge the battery 20 to increase the operating range of the aerial work platform, especially in situations where access to the mains network or other power sources to charge the battery 20 is unavailable. More precisely, the battery 20 is charged via one of three chargers 31 to 33, depending on whether the generator 40 provides three-phase or single-phase current as output.

[0166] The aerial work platform is equipped with a hydraulic circuit that powers the hydraulic cylinder 4 used to operate the lifting mechanism 2. This hydraulic circuit includes one or more hydraulic pumps 50 driven by a second electric motor M2. It also includes a hydraulic distributor 60 through which hydraulic fluid is supplied to various hydraulic actuators, particularly the hydraulic cylinder 4. This also powers other hydraulic actuators (not all shown), such as those used to control the direction of the steerable wheels 10 and / or 11, and those arranged at each corner of the frame 2 to extend or retract the four stabilizing outriggers 19 and release the brakes on the wheels 10, 11. Advantageously, one or two hydraulic actuators (not shown), powered by the hydraulic distributor 60, may also be provided for selectively locking and releasing the differential of one or both of the front axle 12 and the rear axle 13 when the wheels 10 and / or 11 slip.

[0167] Alternatively, multiple electric motors M2 may be provided to drive one or more hydraulic pumps 50 that share a common hydraulic circuit or separate hydraulic circuits. However, it is more economical to drive it using a single hydraulic pump 50 and a single electric motor M2.

[0168] The electric motor M2 is preferably dedicated to driving the hydraulic pump 50 of the hydraulic circuit; if there are multiple pumps, it drives all of them.

[0169] The aerial work platform does not have an internal combustion engine, whether it is used to move the platform along the ground or to operate the lifting mechanism 2 or other hydraulic actuators. In fact, the driving force is always provided to the hydraulic pump by the electric motor M2. In other words, the driving force for operating the lifting mechanism of the work platform is always provided solely by the electric motor M2 (except, of course, for possible gravity). The same is clearly true for the other hydraulic actuators mentioned above.

[0170] Similarly, depending on the circumstances, the driving force for the drive wheels 10 and / or 11 and thus the aerial work platform moving along the ground is always provided solely by the electric motor M1 dedicated to this function (except, of course, the possible effects of gravity).

[0171] Electric motors M1 and M2 are preferably AC (alternating current) electric motors, and more preferably three-phase, because they have better efficiency compared to other types of electric motors. They are powered by battery 20 via corresponding inverters 41 and 42 that convert the DC (direct current) voltage of battery 20 into AC voltage.

[0172] The aerial work platform is also equipped with onboard electronic equipment 70, including, for example, a computer, for controlling the hydraulic distributor 70, chargers 31 to 33, and electric motors M1 and M2 via their respective inverters 41 and 42. Communication links between the control electronic equipment 70 and these components, or at least remote components, can be established via a bus such as a CAN data bus conforming to the ISO 11898 standard.

[0173] The onboard electronics 70 is preferably configured to optimize the power consumption of various components, particularly the electric motors M1 and M2, in order to optimize the autonomy of the battery 20. Specifically, for example, during commands to lift the work platform 3 or move along the ground, it can be advantageously configured to limit the peak power of the electric motors M1 and M2 by gradually supplying power to them. The onboard electronics can also be configured to apply power limiting settings to inverters 41 and 42—and even inverter 22 mentioned below—based on the state of the battery 20, such as its aging or temperature.

[0174] If installed on an aerial work platform, and where the on-board electronics 70 is designed to operate with different types of generators, the on-board electronics 70 can also be provided to identify the type of generator 40, thereby enabling the on-board electronics 70 to adapt the load curve to the maximum power that the generator can provide. Furthermore, the on-board electronics 70 can be designed to automatically start the generator 40 when the charge level of the battery 20 drops below a predetermined threshold. Of course, it can be specified that the operator may be able to start the generator 40 themselves.

[0175] For user safety reasons, it is advantageous that all circuits of the aerial work platform—except for the inputs of chargers 31 to 33—operate at a voltage of less than or equal to 50V, so that the rated voltage of the electric motor is less than 50VAC, and the voltage delivered by battery 20 is less than or equal to 50VDC.

[0176] Figure 5 The available power options for the aerial work platform are displayed.

[0177] To charge from mains power, selector switch 80 allows the first charger 31 to be selectively connected to a single-phase cable or similar with plug 34 – already combined Figure 4As mentioned earlier, this cable is used to connect to a single-phase AC power supply or to a three-phase line for connecting to one phase and the neutral line of a three-phase power supply. The cable also connects two other chargers, 32 and 33, to the corresponding phase and neutral line of the three-phase power supply.

[0178] Selector switch 81 is used to select three-phase power from a cable with plug 35 or similar – already combined Figure 4 As mentioned, it is used to connect to a three-phase AC power supply, or to the three-phase output of the generator 40 via plug 82 and corresponding socket 83.

[0179] The standard single-phase power socket 84 on the work platform 3 can be supplied with the single-phase mains voltage of the relevant country, thereby enabling the user of the work platform 3 to connect electrical appliances to it.

[0180] The socket 84 is powered by a wire that extends downwards to the frame 1, for example, along the lifting mechanism 2.

[0181] This power cord can be specified to be powered in one or more of the following ways:

[0182] - By connecting to a single-phase AC power source, such as via a dedicated plug 85 or other suitable means.

[0183] -By connecting to the output of a dedicated inverter 22, whose input is connected to battery 20, and / or

[0184] - By connecting to the output of generator 40, especially in our example, if it is a three-phase generator, then between one phase and its neutral line.

[0185] The implementation details specify that the selector switch can selectively connect to the power line as needed. In providing all three possibilities, selector switch 86 can be provided to connect to plug 85 or the like, or to power from the aerial work platform; additional selector switch 87 allows selective connection to inverter 22 or to generator 40.

[0186] The connection to the generator 40 can be made, for example, via a standard single-phase plug 88 to a corresponding single-phase socket 89, which is connected to the phase and neutral wires of the generator 40, preferably via a switch 90. The socket 89 is preferably located on the frame 1 and can serve as an auxiliary socket; the user can also use it to connect any electrical appliance.

[0187] It can also be specified that the standard three-phase power socket 91 on the work platform 3 is powered by the three-phase mains voltage of the relevant country, thereby advantageously enabling the user of the work platform 3 to connect electrical appliances to it. The socket 91 is powered via a wire extending downwards to the frame 1, for example, along the lifting mechanism 2. The socket 91 is equipped with a standard three-phase plug 92 for selective connection to either a mains socket or the output socket of the generator 40. Selector switches 80, 81, 86, 87, and 90, as well as the inverter 22, can be controlled by the onboard electronics 70—already integrated... Figure 4 As mentioned—especially according to operator commands—control buttons or similar may be provided on the control panel on the work platform 3 to energize socket 84 and / or socket 91 as needed. Similarly, it may be specified that the operator is allowed to select the power supply for socket 84, for example at control panel 75 on frame 1.

[0188] Figures 6 to 8 The physical layout of the main electrical and hydraulic components on the aerial work platform is explained.

[0189] like Figure 7 As shown, battery 20 and chargers 31, 32, and 33 are located on the first lateral side of frame 1 relative to lifting mechanism 2, i.e., on the left side G in our example. Chargers 31, 32, and 33 are respectively housed in corresponding positions 61, 62, and 63 provided for this purpose. In the case where the aerial work platform has only one or two chargers, positions 62 and / or 63 remain without their chargers 32 and / or 33. Battery management circuit 21 and inverters 41, 42 may also be arranged on this side of frame 1. These components are housed in... Figure 2 and Figure 6 The cover 82 is visible inside.

[0190] like Figure 8 As shown (where wheel tires 10 and 11 and stabilizing feet 19 are omitted for convenience), the electric motor M2 and hydraulic pump 50 are arranged on the opposite lateral side of the frame 1 relative to the lifting mechanism 2, i.e., the right side D in our example. The hydraulic distributor 60 is preferably arranged on the same side. A control panel 75 is also provided, with control electronics 70 arranged behind it. The control panel 75 may also be located at... Figure 1 As seen in [the image], these components are housed within [the container]. Figure 1 , 3 And inside the cover 81 visible in 6. Of course, another fixed or removable control panel can be provided on the work platform 3.

[0191] Because these components are smaller than battery 20, a location 39 is provided on this side of the frame for the removable mounting of generator 40: see [link to relevant documentation]. Figure 3Position 39 is shown without generator 40. Due to its weight, generator 40 is preferably placed in or removed from its position 39 by a forklift. A device for holding generator 40 in its position 39 (not shown) is preferably provided: this device can be of any suitable type. Advantageously, a locking device is provided for generator 40 at its position 39 to prevent theft.

[0192] In the case of an aerial work platform, this platform is used to lift a maximum load of 750 kg to a maximum height of 18 meters. Examples of the dimensions of each component are as follows:

[0193] - Battery 20 has a rated voltage of 48VDC and a capacity of 420A.h.

[0194] Motor M1 is a three-phase AC type, with a rated voltage of 32VAC, 50Hz, and a maximum output power of 6.3kW.

[0195] - Motor M2 is a three-phase AC motor with a rated voltage of 32VAC, 50Hz, and a maximum output power of 10.5kW.

[0196] - Each of chargers 31 to 33 accepts an AC voltage between 110 and 230VAC as input and provides a 48VDC voltage as output, with a maximum power of 3KW.

[0197] Depending on the version, the generator can be selected to provide single-phase AC voltage between 110VAC and 230VAC or three-phase voltage of 400VAC, and provides a maximum power of 6 kW to 9 kW. Its fuel tank capacity can be selected between 10 and 30 liters.

[0198] Special Reference Figures 9 to 15 We will now describe in more detail the location 39 of the aerial work platform configured to receive the generator 40 via a detachable mounting, and the advantageous embodiments of the generator 40.

[0199] like Figure 3 As shown, position 39 is located on the side of frame 1. Figure 3 and Figure 9 As shown, position 39 is open on the outside of the aerial work platform. This allows the generator 40 to be brought into the receiving position and along... Figure 9 The direction F for bringing in / removing the generator 40 is shown to remove it from there, particularly by a forklift. Direction F is preferably substantially horizontal and perpendicular to one side of the receiving position 39 of the frame 1. In other words, the generator 40 is positioned entirely in position 39 by moving horizontally toward position 39 and then finally lowering it into position 39. Alternatively, a door may be provided to close position 39, which is then opened during the operation of installing or removing the generator 40 from position 39.

[0200] Position 39 includes a support member 100 on which the generator 40 rests. In this example, the support member 100 is a continuous extending surface below the generator 40, but it can be made in any suitable form, such as two parallel and spaced apart independent support rods. In this example, position 39 is arranged on the frame 1 adjacent to the wheel 11 of the frame 1, such that when the generator 40 is in position 39, a portion of the generator 40 extends out of the frame 1 above the wheel 11. This measure can limit the dimensions reserved for position 39 on the frame 1, especially since the frame 1 typically does not extend above the wheels 10, 11 of the aerial work platform.

[0201] The support member 100 includes a positioning structure 101 for the generator 40 at position 39. In this embodiment, the positioning structure 101 includes two inclined planes 101a and 101b with opposite directions, offset from each other in a horizontal direction H perpendicular to the input / removal direction F. In this case, direction H corresponds to the longitudinal AV-AR direction of the frame 1. Each of the inclined planes 101a and 101b is a flat surface parallel to the input / removal direction F.

[0202] The inclined planes 101a and 101b are designed to cooperate with the complementary structure arranged on the lower side of the generator 40. Figure 12 The complementary structure is shown in the figure. In this case, it includes, on one hand, a side 201a of the tube 210 that forms an angled channel for the forklift forks. This side 201a of the tube 210 mates with the inclined portion 101a of the support 100. On the other hand, the complementary structure of the generator 40 includes an inclined side 201b, which is configured to mate with the inclined plane 101b of the support 100.

[0203] The shape fit between the positioning structure 101 at position 39 and the complementary structures 201a and 201b of the generator 40 allows for correction of any misalignment of the generator 40 in the direction H relative to the receiving position when it is brought into position 39. This is in Figure 6 The top view of frame 1 shows that arrow F1 indicates the actual input direction of generator 40, which is laterally offset by a distance d from the ideal input direction F centered relative to receiving position 39.

[0204] Similarly, the shape fit between the positioning structure 101 of the receiving position 39 and the complementary structures 201a, 201b of the generator 40 allows for the correction of any angular deviations that may occur in the generator on the horizontal plane relative to the direction of introduction / removal F when the generator 40 is brought into position 39. Figure 6The top view of the middle frame 1 also illustrates this situation, where arrow F2 indicates the actual input direction of generator 40, with an angular offset α on the horizontal plane relative to the input direction F ideally oriented at position 39.

[0205] It will be understood that the shape fit between the positioning structure 101 at position 39 and the complementary structures 201a, 201b of the generator 40 allows for the correction of both centering defects and angular misalignments of the generator 40 in the same manner.

[0206] This automatic correction of the centering and angular orientation of the generator 40 relative to position 39 advantageously allows for proper positioning of the generator 40 in position 39, although subsequent approach maneuvering of the generator 40 to position 39 is not precise. This facilitates the placement of the generator 40 in position 39, whether or not a forklift is used. For transport by forklift, the generator 40 preferably includes two tubes 210, 211 for the forklift forks to pass through, which are preferably arranged on the underside of the generator 40: see Figure 10 The fork passage pipes 210, 211—or alternatively, another structure for fork passage—are made non-through at the rear of the generator 40, which eliminates the risk of interference between the forklift's forks and any other structure of the aerial work platform behind wall 103 or position 39.

[0207] It should be understood that the positioning structure 101 and complementary structures 201a, 201b of position 39 can be made in any other suitable manner. For example, the inclined planes 101a, 101b can be oriented in opposite directions instead of facing each other. Alternatively, there can be only one inclined plane in position 39, with the other replaced by a shoulder similar to the side 201a of the tube 210 of generator 40. Other shapes besides inclined planes are also possible. The positioning structure of receiving position 39 can also be arranged elsewhere outside the support surface 100, such as on the side of position 39.

[0208] Position 39 also includes two notches 102a and 102b provided at the inclined planes 101a and 101b. Generator 40 has two protrusions 202a and 202b on its underside, which engage with the notches 102a and 102b of position 39 respectively when generator 40 is in place in receiving position 39: see [link to relevant documentation]. Figure 13 A partial side view. Protrusion 202a in... Figure 11 It is particularly visible in the enlarged view marked A in the bottom view of the generator.

[0209] The engagement of protrusions 202a and 202b with their corresponding recesses 102a and 102b prevents the generator 40 from being withdrawn from position 39 in the take-in / remove direction. In particular, this allows the forklift forks to be removed from under the generator 40 without the risk of accidentally removing the generator 40 from the receiving position 39 after the operation of placing the generator 40 on position 39 by the forklift.

[0210] It should be understood that the retaining structure formed by notches 102a and 102b and the complementary retaining structure formed by protrusions 202a and 202b are merely one example of implementation and can be implemented in any other suitable manner. For example, notches 102a and 102b can be located elsewhere outside of inclined planes 101a and 101b. There can be only one notch and one protrusion. Structures other than notches and corresponding protrusions can also be considered.

[0211] Generally, it should be noted that the positioning structure 101 and complementary structures 201a, 201b, as well as similar retaining structures 102a, 102b and complementary structures 202a, 202b, can advantageously be fixed structures for position 39 and generator 49, respectively, without any moving parts, which provides robustness and simplicity of implementation.

[0212] Position 39 also includes a rear wall 103, which serves as a stop for positioning the generator 40 in the receiving position along the insertion / removal direction. Specifically, this prevents the generator 40 from being pushed beyond position 39 during placement operations. This stopping function can be achieved by any other suitable means, such as one or more pins protruding from a support.

[0213] Position 39 also includes removable fastening devices for securely holding the generator 40 in position 39 and releasing it to allow removal of the generator 40 from position 39. In a simplified embodiment, these fastening devices may be threaded holes 104 for receiving fastening screws passing through through holes in the legs 204 of the generator 40. Thus, after the generator 40 has been placed in position 39, the removable fastening devices prevent the generator 40 from leaving position 39, while the retaining structure formed by the notches 102a, 102b and the complementary retaining structure formed by the protrusions 202a, 202b leave this risk intact, especially when the aerial work platform is circling on uneven ground. It should be understood that the removable fastening devices can be implemented by any suitable means other than threaded holes for fastening screws.

[0214] Location 39 may also include an exhaust duct 106, which, when placed in location 39, is positioned adjacent to or adjacent to the exhaust outlet of generator 40. In this example, duct 106 is located at the rear wall 103. Figure 14 Pipe 106 is most visible in the partial view. This allows exhaust gases to be vented away from the user, preferably below frame 1.

[0215] As previously mentioned, a locking device can be provided for the generator 40 at its receiving position 39 to prevent theft. Specifically, position 39 may be provided with a structure or device for an anti-theft lock or padlock for the generator 40 that may cooperate with related structures or devices of the generator 40 at position 39. A simple implementation includes a through hole formed in the frame 1 corresponding to the through hole 215 at the height of the generator 40 housing, to allow the anti-theft padlock 299 to be secured: see [link to relevant documentation]. Figure 15 Alternatively, it can be a removable lever that can be held in front of the receiving position 39 to allow passage in front of the generator 40 at position 39, and this lever can be locked to position 39. According to another embodiment, it can be a door to the closing position 39, and can be locked with a key lock or combination lock, etc.

[0216] The aerial work platform may include one or more cable feed guides, for example, for feeding data link cables and / or power connection cables to position 39. Figure 9 In this example, only the power connection cable is shown for such a cable feeder: see cable 105. Power connection cable 105 is provided to connect generator 40 to the power circuit of the aerial work platform, for example, to power the charger of the aerial work platform. The switchboard 220 of generator 40 provides a reference for this. Figure 5 The power outlet 83 has already been mentioned. In another embodiment, the generator 40 can be provided to directly power the electric motor and other circuits of the aerial work platform.

[0217] A data link cable (if provided) is used to connect the onboard electronics 70 of the aerial work platform 1 to the generator 40 at position 39. In this case, the switchboard 220 may have a connector 221 for connecting the corresponding connector of the data link cable of the aerial work platform.

[0218] The above has been referenced Figure 5 The function of the onboard electronic equipment 70 of the aerial work platform 1 relative to the generator 40 was discussed. Generally, it is advantageous for the onboard electronic equipment 70 to control the generator. More advantageously, the generator 40 can be arranged to be exclusively controlled by the onboard electronic equipment 70. In other words, the generator 40 operates only as a subordinate device to the onboard electronic equipment 70. The generator 40 lacks manual or similar control devices for independent control of the generator 40, except perhaps for an emergency stop button and protective devices such as automatic fuses. However, the generator 40 may also lack an emergency stop button, thus this function of the generator 40 can also be managed by the onboard electronic equipment 70 of the aerial work platform.

[0219] The generator's switchboard 220 can also be equipped with other sockets. Specifically, it can be equipped with a single-phase socket 289 powered by the generator 40. Socket 289 can be specifically used to connect a corresponding plug to a cable—not shown—to position 39 via cable feeder 105. This can be a cable with a plug 88—see [link to relevant documentation]. Figure 5 —For insertion into socket 289. Alternatively, a cable with a plug 89 on the other end may also be used: see also... Figure 5 .

[0220] The distribution panel 220 may also be equipped with a socket 290 for connection to mains power. In this case, the generator 40 preferably includes a selector switch that allows selective power supply from the socket 290 to the power socket 83 via the generator 40 itself or when it is connected to mains power. This selector switch is preferably controlled by on-board electronics 70.

[0221] The vehicle-mounted electronic equipment 70 may also include a wireless communication module, thereby enabling remote control of the generator 40. In particular, the vehicle-mounted electronic equipment 70 may be configured to allow remote starting and / or remote disabling of the generator 40 via the wireless communication module.

[0222] Special reference Figures 17 to 27 The following will now describe the previous reference. Figures 9 to 16 The described embodiment of the aerial work platform location 39 and generator 40 is an improvement. All descriptions regarding the structure and function of location 39 and generator 40, and how the latter is mounted on location 39, still apply to this variant, except for the differences described below. Therefore, except for added or different components, the use of... Figures 9 to 16 In the embodiments, the same reference numerals are used to indicate the corresponding elements.

[0223] In this variant, generator 40 is equipped with a locking system 300, which is configured to automatically lock generator 40 in position 39 after it is placed and automatically unlock it upon removal. Because the locking is automatic, the locking system 300 allows for compensation for accidental negligence in securing generator 40 in its position 39 by manually tightening it: see reference in Figures 9 to 16 As mentioned in the embodiments, and through Figure 9 and Figure 10 More specifically, the manual tightening system for the legs 204 and threaded holes 104 is described. Furthermore, the unlocking of the locking system 300 is also automatic and requires no manual intervention. Optionally, the manual tightening system can even be omitted.

[0224] As mentioned earlier, the placement of generator 40 at position 39 is best accomplished with the assistance of a forklift CE. Figure 18As shown. The locking system 300 is adapted to cooperate with the forks of the forklift CE so that it can be unlocked when it is biased into the locked position without the forks.

[0225] The locking system 300 is configured to cooperate with at least one retaining member, preferably arranged in a fixed manner in position 39. Figure 17 In the example shown, there is only one retaining member. This is fixedly disposed in position 39 in the form of a pin 120. The pin 120 is preferably disposed on the support 100 between inclined planes 101a and 101b. The pin 120 is fixed there at a certain distance from the support 100 by two bearings 121 at two opposite ends and extends horizontally. Preferably, it is fixed in the region of the rear half of position 39 relative to the direction of introduction F, so as to prevent the pin 120 from being accidentally struck by external components when the generator 40 is not in position 39, or even during the operation of placing the generator 40 in position 39.

[0226] Two notches 102a' and 102b' are provided in the inclined planes 101a and 101b at position 39 and Figures 9 to 16 In the embodiment, the notches 102a and 102b correspond to each other. Considering the insertion direction F, they are located in position 39 at a depth preferably the same as the depth of pin 120. In other words, pin 120 is positioned between and aligned with the two notches 102a' and 102b'. Although not shown in the figures, the protrusions 202a and 202b of generator 40 are therefore also offset below generator 40 at a corresponding depth. It is understood that locking system 300 is positioned between and aligned with the two offset protrusions 202a and 202b. This avoids the risk of collision with pin 120 when generator 40 is placed in position 39. It also ensures that generator 40 is correctly inserted into its position 39, thereby allowing locking system 300 to engage well with the retaining member (in this case, pin 120).

[0227] The locking system 300 is disposed in a corresponding area on the underside of the generator 40. Preferably, the locking system 300 is embedded in the housing of the generator 40 so that no part of the generator 40 protrudes from the underside of the generator 40. This prevents the locking system 300 from being subjected to impacts during handling, or prevents the generator from resting on the locking system 300 when the generator 40 is placed on any surface other than position 39 of the aerial platform.

[0228] The locking system 300 includes at least one movable locking member configured to cooperate with at least one retaining member to hold the generator 40 in position 39 of the aerial work platform, which then corresponds to a locked position of the locking member. The locking member can be actuated to an unlocked position to release it from the retaining member, thereby allowing the generator 40 to be removed from position 39.

[0229] In the illustrated example, the locking system 300 includes two locking members, each formed as a hook 301, 302, configured to engage with the pin 120. These two hooks 301, 302 prevent the generator 40 from being lifted from position 39 and thus removed therefrom. Figure 19 The illustration shows the engagement of two hooks 301 and 302 with pin 120.

[0230] The two hooks 301 and 302 can be actuated to disengage them from the pin 120, which then allows the generator 40 to be lifted from position 39 so that the protrusions 202a and 202b of the generator 40 and the recesses 102a' and 102b'—functionally corresponding to Figures 9 to 16 The notches 102a and 102b of the embodiment are disengaged, and then the generator 40 is disengaged from position 39 along the input / removal direction F.

[0231] Figures 19 to 27 The locking system 300 is shown in more detail, with hooks 301 and 302 engaging with pin 120. Hook 301 is pivotally mounted on shaft 310, which is positioned in a fixed location on the underside of generator 40. Shaft 310 preferably extends horizontally. Hook 301 is elastically biased toward the position engaging with pin 120, for example by the action of tension spring 312. Actuating member 311 is associated with hook 301. In this example, it is implemented in the form of a paddle. Actuating member 311 is preferably fixedly associated with hook 301, for example by welding or by merging materials. The free end of actuating member 311 extends into fork tooth channel 210 so that it is actuated by the fork teeth of forklift CE when the fork teeth of forklift CE are inserted into the fork tooth channels 210, 211 of generator 40. Under the actuation of the fork teeth, the actuating member 311 retracts from the fork tooth channel 210, and the hook 301 pivots under the restoring force of the spring 312, thereby disengaging the hook 301 from the pin 120.

[0232] Preferably, when the generator 40 is oriented according to its orientation when positioned in position 39 on the aerial work platform, the hook 301 is also biased towards the position where it engages with the pin 120 under gravity. This effect can be achieved by the weight of the actuating member 311. This gravitational bias provides safety in the event that the elastic bias of the hook 301 towards the locked position by spring or other means fails.

[0233] Hook 302 operates on the same principle as hook 301, but its pivoting direction is opposite. Therefore, the two hooks 301 and 302 engage with pin 120 from opposite sides and clamp pin 120, providing a very reliable hold for generator 40 in position 39, even if the operator forgets to move generator 40 in that position. Figures 9 to 16 In the embodiment mentioned above, the leg 204 and the threaded hole 104 are screwed into position 39.

[0234] Furthermore, the contours of the contact surfaces of hooks 301 and 302 with pin 120 are preferably designed to firmly hold generator 40 in position 39 without creating gaps, thus preventing the generator 40 from being left in place if the operator forgets. Figures 9 to 16 In the embodiment mentioned above, when the leg 204 and threaded hole 104 are screwed into position 39, vibration of the generator 40 in position 39 is substantially limited. More specifically, the profile of each hook 301, 302 can be defined to provide a gradual tightening of the hook to pin 120, thereby providing a wedge effect. In other words, the distance from the contact surface of hook 301 to its axis of rotation 310 decreases from its free end to the bottom of hook 301, and the same is true for hook 302.

[0235] In a simpler embodiment, a locking system 300 may be used that includes only one or another type of single movable locking member, such as hooks 301 and 302.

[0236] Due to its operation in the opposite pivoting direction, the mounting and actuation system of hook 302 is adapted to reverse the direction of its rotation relative to its actuating member 321. An example of achieving this function is shown in the figure, specifically... Figure 20 and Figure 21 It can be achieved by making the hook 302 and its actuating member 321 into two separate components. The hook 302 is pivotally mounted to a first shaft 320, and its actuating member 321 is pivotally mounted to a second shaft 323 that is parallel to and spaced from the first shaft 320. Shafts 320 and 323 preferably extend horizontally. In this example, the actuating member 321 also has a paddle shape. The hook 302 is elastically biased toward the position where it engages with the pin 120, for example by means of a tension spring 322.

[0237] The free end of the actuating member 321 extends into the fork tooth channel 211 so that it can be actuated by the fork tooth of the forklift CE when the fork tooth of the forklift CE is inserted into the fork tooth channels 210, 211 of the generator 40. When the actuating member 321 is actuated by the fork tooth of the forklift CE, it retracts by pivoting about the shaft 323 and pushes against the eccentric portion 302a of the hook forming member 302 with the eccentric extension 321a, thereby causing the hook 302 to pivot against the force of the spring 322 in the opposite direction of the actuating member 321. In this way, the hook 302 disengages from the pin 120.

[0238] As can be seen from the accompanying drawings, only the ends of the actuating members 311 and 312 extend into their respective fork tooth channels 210 and 211, while the rest of the locking system 300 is arranged outside the fork tooth channels 210 and 211 of the generator 40. The fact that each of the actuating members 311 and 312 extends into its respective fork tooth channel 210 and 211 helps to balance the thrust of the forklift CE's forks when they are inserted into the channels 210 and 21. Figure 22 and Figure 23 The locking members 301, 302 in the unlocked position are shown, each figure corresponding to a view from the opposite side of the locking system 300, and the presence of the corresponding fork teeth 401, 402 of the forklift is illustrated. Optionally, the actuating members 311, 312 may be configured to extend into the same fork tooth channels 210 or 211.

[0239] It is understood that each of the fork passages 210, 211 preferably has a rectangular cross-sectional dimension corresponding to the fork teeth of the forklift. For example, the fork passage may be formed by one or more pipe segments having a preferred rectangular cross-section, and / or by a ring having a preferred rectangular cross-section and / or by matching openings in the housing of the generator 40. However, the fork passage may be defined in ways other than a closed profile cross-section: for example, the profile may open downwards, or the fork passage may simply be defined by a concave wedge in the form of two vertical walls, thus defining a fork passage that is open in the lateral direction and downwards.

[0240] According to another embodiment, two locking members 301 and 302 can be actuated by a common actuating member. In particular, locking member 301 and its actuating member 311 can be made as a single unit, or they can be used to actuate locking member 302, which is made as a separate component.

[0241] It is understandable that the locking system 300 and the corresponding arrangement of position 39 described above can be applied to any kind of equipment that is configured to be detachably placed in or on any machine in a dedicated location by a forklift, especially self-propelled machines.

[0242] It can be further understood that, by convention, the horizontal direction of the axis of the locking system of generator 40 or other equipment will be understood as the direction of generator 40 or related equipment in or above a dedicated position on an aerial work platform or other machine placed on a horizontal ground.

[0243] Figure 28 and Figure 29 It shows the method of passing through Figure 9 and Figure 10The screws and threaded holes 104 on the leg 204 of the generator 40 shown in the figure represent an alternative embodiment of a system for manually securing the generator 40 in position 39. The tightening system according to this embodiment is suitable for both... Figures 1 to 16 The embodiments are also applicable to Figures 17 to 27 Examples of implementations.

[0244] In this embodiment, the fastening screw is locked to the generator 40. Figure 28 and Figure 29 This is illustrated by the screw positioned in position 39 of the aerial work platform, which is a threaded hole 104. For this purpose, a sleeve 402 is attached to a vertical plate 400 of the generator 40 housing. A screw 410 passes through holes in both the sleeve 402 and the plate 400. A lock nut 411 is permanently mounted on the threaded portion of the screw 410. The lock nut prevents the screw 410 from being removed from the holes in both the sleeve 402 and the plate 400. Therefore, the screw 410 is locked. Another drilled sleeve 401 is fixedly attached to the plate 400 on the opposite side of the sleeve 402. It protects the threaded portion of the screw 410 and the lock nut 411 housed in the through-hole of the sleeve 401.

[0245] Furthermore, a spring arranged in sleeve 402 elastically biases the screw head in the direction in which the screw 410 is removed from sleeve 402. Therefore, when the generator 40 is in position 39 of the aerial work platform, the operator can immediately see whether the screw 410 is screwed in—without the aid of a special sensor or signal. Moreover, the tightening system is embedded relative to the wall of the generator 40 housing, so even when not screwed in, the screw head 410 will not protrude outside the generator 40, thus protecting the screw head from accidental impacts. Furthermore, because the return spring 420 biases the screw 410 in the opposite direction, the free end of the screw 410 will not protrude from sleeve 401 when not screwed in, which also protects the free end of the screw 410 from accidental impacts.

[0246] When the generator 40 is properly positioned in position 39 of the aerial work platform, the sleeve 401 abuts against plate 39a or similar surface of position 39. The free end of the screw 410 is positioned correspondingly to the nut 39b that is fixedly attached to plate 39a of position 39. Alternatively, it may be a threaded hole directly drilled in a portion of position 39. The operator then screws the screw 410 into the nut 39b to secure the generator 40 in position 39. Figure 28 This describes the situation before screw 410 is screwed into nut 39b, and Figure 29 This describes the situation after screw 410 is screwed into nut 39b.

[0247] Reference Figure 28 and Figure 29 The described manual fastening system can also be used to fasten other equipment besides generators in designated positions.

[0248] Of course, the present invention is not limited to the examples and embodiments described and illustrated, but many variations will be apparent to those skilled in the art. Therefore, it can be applied to aerial work platforms with different types of lifting mechanisms. For example, this could be an articulated telescopic boom supporting the work platform 3 at its upper end. In this case, a turret mounted on the frame 1 can also be included to pivot about the vertical axis supporting the telescopic boom. In the latter case, electrical and hydraulic components, in addition to the motor M1 for driving the front and / or rear wheels 10, 11, can be advantageously arranged on the turret. In this case, the detachable mounting location 39 for the generator 40 is preferably arranged on the turret.
