Description

Technical Field

[0001] This application relates to the technical field of mobile rebar processing equipment, specifically to a vehicle-mounted automatic rebar feeding device and method. Background Technology

[0002] In large-scale construction projects such as nuclear power plants, hydropower plants, airports, and large public residential buildings, centralized rebar loading equipment is typically installed around the construction site to achieve standardized and efficient rebar loading. This equipment loads rebar in batches based on orders from the production management system. After loading, the rebar can be further processed. Once processed, it is transported to various work areas via on-site trailers, forming a typical rebar supply model for construction scenarios.

[0003] However, construction sites often experience unforeseen circumstances such as deviations from detailed design drawings, errors in on-site binding operations, and discrepancies between the actual site and the design plan, which can easily lead to sporadic material replenishment needs. These replenishment tasks are characterized by their significant temporariness, urgency, and uncertainty of demand, and are mostly for single pieces or small batches of complex-shaped materials.

[0004] From the perspective of the existing supply system, sporadic rebar replenishment from centralized loading equipment requires multiple steps, including application, approval, and production scheduling. The overall response efficiency is insufficient to match the urgency of the replenishment tasks. If traditional rebar loading equipment is deployed on-site to shorten the replenishment cycle, it requires significant space for storing finished and semi-finished rebar. However, construction sites typically have limited space, and the dynamic changes in construction progress make it difficult to reserve large, fixed storage areas, resulting in low feasibility for traditional equipment configurations. Therefore, large-scale construction projects urgently need a mobile rebar loading device that can address the needs of sporadic rebar replenishment on-site. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of this application is to provide a vehicle-mounted automatic rebar feeding device and method.

[0006] According to one aspect of this application, a vehicle-mounted automatic rebar feeding device is provided, comprising: Vehicle-mounted work platform; A categorized steel bar storage module is installed on the vehicle-mounted work platform and is used to place steel bars of different specifications; A rebar picking component, mounted on the vehicle-mounted work platform, is used to pick up rebars one by one from the classified rebar storage module; Several sets of steel bar cutting units are installed on the vehicle-mounted work platform to cut steel bars into preset lengths; A steel bar scrap collection bin is located on one side of the vehicle-mounted work platform and is used to collect steel bar scrap. A rebar transfer unit, located on the vehicle-mounted operating platform, is used to transfer rebar from the rebar picking component to the rebar cutting unit, or to transfer rebar waste cut by the rebar cutting unit to the rebar waste collection bin. The intelligent rebar feeding system is used to generate a rebar production material list and control the classified rebar storage module, the rebar picking component, the rebar cutting unit, and the rebar transfer unit to complete the rebar feeding according to the rebar production material list.

[0007] Optionally, the classified rebar storage module includes a guide rail, several raw material storage bins, a bin transfer component, and a material support pallet. The guide rail is placed on the platform of the vehicle-mounted work platform, and the several raw material storage bins are placed on the guide rail. The raw material storage bins are arranged along the length of the rebar, and each raw material storage bin is used to hold rebar raw materials of different diameters. The bin transfer component is connected to the guide rail and can move horizontally along a direction perpendicular to the length of the rebar. The bin transfer component is equipped with a lifting component, and the material support pallet is installed on the lifting component. The bin transfer component is used to move each raw material storage bin through its own horizontal movement and the lifting component, thereby changing the position of the raw material storage bins. The material support pallet is used to support the raw material storage bins during the movement of the raw material storage bins.

[0008] Optionally, the rebar picking component includes a fixed support frame, a magnetic gripper, an end gripper clamp, a movable clamping component, a picking beam, a guide component, and a lifting power unit. The fixed support frame is connected to the vehicle-mounted work platform. The guide component and the lifting power unit are both fixedly installed on the fixed support frame. The magnetic gripper is movably connected to the fixed support frame and is used to pick up the end of a single rebar in the raw material storage bin. The picking beam is movably connected to the guide component and is arranged along the length of the rebar. The lifting power unit is connected to the picking beam and is used to drive the picking beam to move up and down along the guide component. The end gripper clamp is connected to the picking beam and is used to clamp the end of a single rebar.

[0009] Optionally, the end gripper is connected to one end of the pickup beam near the magnetic gripper.

[0010] Optionally, the picking beam is provided with a plurality of rotating support seats, each rotating support seat being spaced apart along the length of the picking beam. Each rotating support seat can rotate 90 degrees around its own axis. A movable clamping component is movably connected to the picking beam along the length of the reinforcing bar. The movable clamping component is used to clamp the reinforcing bar and carry the clamped reinforcing bar to move away from the raw material storage bin along the length of the picking beam. When the movable clamping component moves beyond the arrangement position of a certain rotating support seat, the rotating support seat rotates 90 degrees to provide upward support for the reinforcing bar. As the movable clamping component continues to move, each rotating support seat rotates in sequence and supports the reinforcing bar, so that a single reinforcing bar is separated from the raw material storage bin.

[0011] Optionally, the bottom end of the rotating support is inclined, so that when the end gripping clamp and the movable clamping component are not clamping the reinforcing bar, the reinforcing bar supported on the rotating support can fall into the reinforcing bar transfer unit under its own gravity.

The material transfer support frame is connected to the vehicle-mounted work platform, and the material receiving beam is connected to the material transfer support frame via the lifting and tilting mechanism. The material receiving beam is arranged along the length of the rebar. The lifting and tilting mechanism can drive the material receiving beam to move up and down along the material transfer support frame and drive the material receiving beam to rotate around its own axis by a preset angle. The material receiving beam is used to receive the rebar picked up by the rebar picking component and transfer the rebar to the rebar cutting unit.

[0013] Optionally, the material receiving beam is provided with a V-shaped groove for receiving a single steel bar, and the groove opening size matches the outer diameter of the steel bar.

[0014] Optionally, the vehicle-mounted operating platform is equipped with a sawing guide rail, which is arranged along the length of the reinforcing bar. The bottom of each group of reinforcing bar cutting units is equipped with a sliding pair that matches the sawing guide rail. The reinforcing bar cutting unit can move along the length of the sawing guide rail to a preset position. The reinforcing bar cutting unit includes a sawing clamping component and a saw blade. The sawing clamping component is used to position and clamp the reinforcing bar before sawing, and the saw blade is used to cut the reinforcing bar to a fixed length. Sawing infeed and discharge components are arranged on both sides of each group of reinforcing bar cutting units. The sawing infeed and discharge components include an inclined slide plate and a reverse slide plate that can be lifted and lowered independently. The inclined slide plate is used to transport the cut reinforcing bar to the next level of reinforcing bar processing station, and the reverse slide plate is used to receive reinforcing bar waste and transfer the reinforcing bar waste to the reinforcing bar waste collection bin through the reinforcing bar transfer unit.

[0015] According to another aspect of this application, a vehicle-mounted automatic rebar feeding method is provided, the method comprising: The intelligent rebar feeding system receives rebar processing orders, generates rebar production material lists, and sends these lists to the categorized rebar storage module, rebar picking components, rebar cutting unit, and rebar transfer unit. The rebar production material lists include rebar specifications, finished rebar length, and rebar quantity. The categorized rebar storage module includes several raw material storage bins. The classified rebar storage module moves the raw material storage bin containing the corresponding rebar to the designated pickup position according to the rebar specifications. The rebar picking unit picks up individual rebars from the raw material storage bin and sends them one by one into the rebar transfer unit according to the quantity of rebars. The rebar cutting unit moves to the designated position according to the length of the finished rebar, the rebar transfer unit sends the rebar into the rebar cutting unit, and after the sawing is completed, the rebar waste is returned to the rebar waste collection bin through the rebar cutting unit. The finished steel bars that have been sawn are sent one by one to the subsequent processing steps for further processing.

[0016] This application provides a vehicle-mounted automatic rebar feeding device. The device can be moved with the construction site via a vehicle-mounted operating platform, enabling nomadic production and reducing rebar transportation time. The categorized rebar storage module can store rebar raw materials of various specifications, eliminating the need for an additional raw material storage yard and saving on-site space. The categorized rebar storage module, in conjunction with the rebar picking component, automatically retrieves the rebar of the required specifications from the rebar production list, avoiding the problem of incorrect specification retrieval caused by manual operation. The intelligent rebar feeding system schedules production according to order sequence, and finished products can be immediately packaged and picked up by a tower crane or transport vehicle, eliminating the need for a finished product storage yard and saving more than 50% of storage space.

[0026] Reference Figure 1 As shown in some specific embodiments of this application, the vehicle-mounted automatic rebar feeding device includes a vehicle-mounted operating platform, a classified rebar storage module, a rebar picking component, several sets of rebar cutting units, a rebar waste collection bin 500, a rebar transfer unit, and a rebar intelligent feeding system. The classified rebar storage module, the rebar picking component, the several sets of rebar cutting units, the rebar transfer unit, and the rebar intelligent feeding system are all located on the vehicle-mounted operating platform. The classified rebar storage module is used to store rebars of different specifications; the rebar picking component is used to pick up the rebars in the classified rebar storage module one by one; the several sets of rebar cutting units are used to cut the rebars into preset lengths; the rebar waste collection bin 500 is located on one side of the vehicle-mounted operating platform and is used to collect rebar waste; the rebar transfer unit is used to transfer the rebars from the rebar picking component to the rebar cutting unit, or to transfer the rebar waste cut by the rebar cutting unit to the rebar waste collection bin 500; the rebar intelligent feeding system is used to generate a rebar production material list and control the classified rebar storage module, the rebar picking component, the rebar cutting unit, and the rebar transfer unit to complete the rebar feeding according to the rebar production material list.

[0027] For example, the classified rebar storage module, rebar picking component, rebar cutting unit, rebar waste collection bin 500, rebar transfer unit, and intelligent rebar feeding system are all mounted on the vehicle-mounted work platform 600 and have their own power supply. They can be moved with the construction site. The vehicle-mounted work platform 600 enables flexible relocation and nomadic feeding. The vehicle-mounted work platform 600 is equipped with a vehicle body stability support device. When the vehicle-mounted work platform travels to the construction site, the vehicle body stability support device extends and supports the ground, so that the feeding device is stable and does not shake during the feeding process. The intelligent rebar feeding system includes an electrical control cabinet, a PLC control system, a computer, an air compressor station, and a hydraulic station. All these components are housed within the electrical control cabinet. The computer contains automatic optimization cutting algorithm software, which remotely receives rebar order information, generates a rebar production list based on the existing algorithm, and sends it to the PLC control system. The PLC control system then controls the categorized rebar storage module, rebar picking components, rebar cutting unit, and rebar transfer unit to automatically process rebar according to the production list. The PLC control system can receive rebar orders at the construction site and generate miscellaneous material lists, optimizing the cutting scheme, reducing loss rates, and shortening rebar production time.

[0028] In the embodiments described above, the vehicle-mounted operating platform 600 allows the device to be moved with the construction site, enabling nomadic production and reducing steel bar transportation time. The categorized steel bar storage module can store steel bar raw materials of various specifications, including diameter, length, material, and strength grade. This eliminates the need for an additional raw material storage yard, saving on-site space. The categorized steel bar storage module, in conjunction with the steel bar picking component, automatically retrieves steel bars of the required specifications from the production bill of materials, avoiding the problem of incorrect specification retrieval due to manual operation. The automatic steel bar picking by the steel bar picking component and the fixed-length sawing process by the steel bar cutting unit do not require axial movement of the steel bars. The overall length of the device only needs to correspond to the length of the steel bars, eliminating the need to double the number of devices and making the device lighter and easier to implement a vehicle-mounted design. The intelligent steel bar feeding system schedules production according to order sequence. Finished products can be immediately packaged and picked up by a tower crane or transport vehicle, eliminating the need for a finished product storage yard and saving more than 50% of storage space.

[0029] In some specific embodiments of this application, the classified rebar storage module includes a guide rail 101, several raw material storage bins 102, a bin transfer component 103, and a material support pallet 104. The guide rail 101 is placed on the plate of the vehicle-mounted work platform 600, and the several raw material storage bins 102 are placed on the guide rail 101. The raw material storage bins 102 are arranged along the length direction of the rebar, and each raw material storage bin 102 is used to hold rebar raw materials of different diameters. The bin transfer component 103 is connected to the guide rail 101 and can move horizontally along a direction perpendicular to the length of the rebar. The bin transfer component 103 is equipped with a lifting component, and the material support pallet 104 is installed on the lifting component. The bin transfer component 103 is used to move each raw material storage bin 102 by its own horizontal movement and the lifting component, thereby changing the position of the raw material storage bins 102. The material support pallet 104 is used to lift the raw material storage bins 102 during the movement of the raw material storage bins 102.

[0030] For example, the classified rebar storage module is provided with several spaced guide rails 101 and two hopper transfer components 103. The guide rails 101 are horizontally arranged along the direction perpendicular to the length of the rebar, and the two hopper transfer components 103 are respectively arranged on the guide rails 101 at both ends. When a raw material storage hopper 102 needs to be moved, the hopper transfer component 103 moves along the length direction of the guide rail 101 to the end of the raw material storage hopper 102, the material support plate 104 lifts the raw material storage hopper 102, and then the lifting component drives the material support plate 104 to rise (the rising height is such that there is no interference between the raw material storage hoppers 102). When the hopper transfer component 103 moves to the target position, the lifting component drives the material support plate 104 to fall, and the raw material storage hopper 102 is placed back on the guide rail 101.

[0031] In the above embodiments of this application, the categorized rebar storage module is located at the bottom layer of the device, excluding the vehicle-mounted work platform. The guide rail 101 is installed on the low plate of the vehicle-mounted work platform, serving to support the various raw material storage bins 102 and to allow the material transfer components 103 at both ends to move between the raw material storage bins 102. The device of this embodiment comes with a multi-station raw material storage bin 102, which can store rebar of various specifications in a small space. Multiple raw material storage bins 102 are placed parallel to each other on the guide rail 101, and each raw material storage bin 102 can operate independently, holding rebar of different specifications. The material transfer components 103 have the function of moving and lifting between the raw material storage bins 102. When two sets of material transfer components 103 simultaneously raise the material carrying pallet 104, the raw material storage bin 102 can be lifted to a high position. Combined with the lateral movement of the material transfer components 103, the interactive use function of the raw material storage bins 102 can be realized.

[0032] In some specific embodiments of this application, the rebar picking component includes a fixed support frame, a magnetic gripper 201, an end gripper 202, a movable clamping component 203, a picking beam 205, a guide member 206, and a lifting power unit 207. The fixed support frame is connected to the vehicle-mounted work platform 600. The guide member 206 and the lifting power unit 207 are both fixedly installed on the fixed support frame. The magnetic gripper 201 is movably connected to the fixed support frame and is used to pick up the end of a single rebar in the raw material storage bin 102. The picking beam 205 is movably connected to the guide member 206 and is arranged along the length of the rebar. The lifting power unit 207 is connected to the picking beam 205 and is used to drive the picking beam 205 to move up and down along the guide member 206. The end gripper 202 is connected to the picking beam 205 and is used to clamp the end of a single rebar.

[0033] For example, the magnetic gripper 201 may be a magnet.

[0034] In some specific embodiments of this application, the end gripper 202 is connected to one end of the pickup beam 205 near the magnetic gripper 201.

[0035] In some specific embodiments of this application, a plurality of rotating support seats 204 are provided on the picking beam 205. Each rotating support seat 204 is spaced apart along the length direction of the picking beam 205. The rotating support seat 204 can rotate 90 degrees around its own axis. The movable clamping component 203 is movably connected to the picking beam 205 along the length direction of the reinforcing bar. The movable clamping component 203 is used to clamp the reinforcing bar and carry the clamped reinforcing bar to move away from the raw material storage bin 102 along the length direction of the picking beam 205. When the movable clamping component 203 moves beyond the arrangement position of a certain rotating support seat 204, the rotating support seat 204 rotates 90 degrees to form an upward support for the reinforcing bar. As the movable clamping component 203 continues to move, each rotating support seat 204 rotates in sequence and supports the reinforcing bar, so that a single reinforcing bar is separated from the raw material storage bin 102.

[0036] In the above embodiments of this application, the main function of the rebar picking component is to remove the rebar from the raw material storage bin 102, separate it into individual rebars, and roll the rebars into the rebar transfer unit. One end of the rebar picking component is equipped with a liftable magnetic gripper 201. When the magnetic gripper 201 descends, it attracts the rebars on the surface of the raw material storage bin 102. Subsequently, the magnetic gripper 201 rises, and one end of the rebar is attracted by the magnetic gripper 201. The movable clamping component 203 is initially positioned near the end gripping clamp 202. Subsequently, the end gripping clamp 202 and the movable clamping component 203 simultaneously clamp a single rebar. After the clamping is stable, the magnetic gripper 201 continues to rise and detach from the rebar. The movable clamping component 203 moves along the length of the picking beam 205. Multiple rotating support seats 204 are evenly distributed on the picking beam 205. When the movable clamping component 203 has not moved past the rotating support seat 204, the rotating support seat 204 avoids the movable clamping component 203 and is in a horizontal state. When the movable clamping component 203 moves past the rotating support seat 204, the rotating support seat 204 rotates 90 degrees to a vertical state, so that the rebar is supported in sequence. When the movable clamping component 203 moves to the other end of the picking beam 205, it can work with all the rotating support seats 204 to sort and separate the single rebar from the raw material storage bin 102.

[0037] In some specific embodiments of this application, the bottom end of the rotating support 204 is inclined. When the end gripping clamp 202 and the movable clamping component 203 are not clamping the reinforcing bar, the reinforcing bar supported on the rotating support 204 can fall into the reinforcing bar transfer unit under its own gravity.

[0038] In the above embodiments of this application, the picking beam 205 is lifted along the guide member 206 under the drive of the lifting power unit 207, and the end gripping clamp 202 and the movable clamping component 203 are released, so that the steel bar can fall into the material receiving beam 403 of the steel bar transfer unit along the inclined surface of the rotating support seat 204 under the action of gravity.

[0039] In some specific embodiments of this application, the rebar transfer unit includes a material transfer support frame 401, a lifting and tilting mechanism 402, and a material receiving beam 403. The material transfer support frame 401 is connected to the vehicle-mounted work platform 600, and the material receiving beam 403 is connected to the material transfer support frame 401 through the lifting and tilting mechanism 402. The material receiving beam 403 is arranged along the length direction of the rebar. The lifting and tilting mechanism 402 can drive the material receiving beam 403 to move up and down along the material transfer support frame 401, and drive the material receiving beam 403 to rotate around its own axis by a preset angle. The material receiving beam 403 is used to receive the rebar picked up by the rebar picking component and transfer the rebar to the rebar cutting unit.

[0040] In the above embodiments of this application, the material receiving beam 403 is used to buffer a single rebar. Under the action of the lifting and tilting mechanisms 402 at both ends of the material transfer support frame 401, the material receiving beam 403 rises to its highest point along the height direction of the material transfer support frame 401, and then rotates 90 degrees to slide the rebar into the rebar cutting unit.

[0041] In some specific embodiments of this application, the material receiving beam 403 is provided with a V-shaped groove for receiving a single steel bar, and the groove opening size matches the outer diameter of the steel bar.

[0042] In some specific embodiments of this application, a sawing guide slide rail 303 is provided on the vehicle-mounted operating platform. The sawing guide slide rail 303 is arranged along the length direction of the steel bar. The bottom of each group of steel bar cutting units is provided with a sliding pair that matches the sawing guide slide rail 303. The steel bar cutting unit can move along the length direction of the sawing guide slide rail 303 to a preset position. The steel bar cutting unit includes a sawing clamping component 301 and a saw blade. The sawing clamping component 301 is used to position and clamp the steel bar before sawing. The saw blade is used to cut the steel bar to a fixed length. Sawing feed and discharge components 302 are arranged on both sides of each group of steel bar cutting units. The sawing feed and discharge components 302 include an independently liftable inclined slide plate and a reverse slide plate. The inclined slide plate is used to transport the cut steel bar to the next level steel bar processing station. The reverse slide plate is used to receive steel bar waste and transfer the steel bar waste to the steel bar waste collection bin 500 through the material receiving beam 403 in the steel bar transfer unit. The device can automatically return the steel bar waste to the steel bar waste collection bin 500 so that the steel bar waste and finished steel bar are stored separately.

[0043] For example, the clamping surface of the sawing clamping component 301 is adapted to the outer wall of the steel bar, the cutting direction of the saw blade is perpendicular to the axis of the steel bar, and the steel bar waste collection bin 500 is arranged on the low receiving side of the material receiving beam 403 to receive the waste material.

[0044] In the above embodiments of this application, the rebar cutting unit and the rebar transfer unit are linked to achieve the function of cutting rebar to a fixed length, sending the finished products one by one to the next level rebar processing station, and returning the remaining waste material to the rebar waste collection bin 500. The next level rebar processing station is located on the finished product output side of the sawing feed assembly 302, adapted to the tilt direction of the inclined slide. After the material receiving beam 403 slides the rebar into the rebar cutting unit, each rebar cutting unit moves to the designated position along the sawing guide rail 303 according to the rebar length on the rebar production bill. Upon receiving the rebar raw material, the sawing clamping component 301 of each rebar cutting unit clamps the rebar, and the saw blade starts to cut the rebar to the required fixed length. Each rebar cutting unit is equipped with sawing feed and discharge components 302 on both sides. When the inclined slide plate on one side of the sawing feed and discharge component 302 rises, each section of finished rebar is sequentially fed into the next rebar processing station. The reverse slide plate on the other side rises, cooperating with the material receiving beam 403 in the middle position, to return the last section of waste material to the material receiving beam 403. At this point, the material receiving beam 403 returns to its lowest point and rotates 90 degrees in the opposite direction, turning the waste material into the rebar waste collection bin 500, thus completing the fixed-length cutting step for one rebar raw material. Neither the automatic rebar pickup of the rebar pickup component nor the fixed-length sawing process of the rebar cutting unit requires axial movement of the rebar. The overall length of the device only needs to correspond to the length of the rebar, eliminating the need to double the number of devices, making the device lighter and easier to implement in a vehicle-mounted design.

[0045] In some specific embodiments of this application, the PLC control system of the intelligent rebar feeding system moves the raw material storage bin 102 by controlling the movement of the material bin transfer component 103; picks up rebar by controlling the magnetic gripper 201 to absorb, the picking beam 205 to move, the rotating support 204 to rotate, and the end gripper 202 and the movable clamping component 203 to clamp; transfers rebar by controlling the movement of the lifting and flipping mechanism 402 and the material receiving beam 403; and cuts rebar by controlling the movement of the rebar cutting unit and the saw.

[0046] Reference Figure 2 and Figure 3 As shown, based on the same inventive concept, another embodiment of this application provides a vehicle-mounted automatic rebar feeding method, which includes: S1. The intelligent rebar feeding system receives rebar processing orders, generates rebar production material lists, and sends the rebar production material lists to the classified rebar storage module, rebar picking components, rebar cutting unit, and rebar transfer unit. The rebar production material lists include rebar specifications, finished rebar length, and rebar quantity. S2. The classified rebar storage module moves the raw material storage bin 102 containing the rebar of the corresponding specification to the designated pickup position according to the rebar specification. S3. The rebar picking component picks up a single rebar from the raw material storage bin 102 and sends it into the rebar transfer unit one by one according to the number of rebars. S4. The steel bar cutting unit moves to the designated position according to the length of the finished steel bar. The steel bar transfer unit sends the steel bar into the steel bar cutting unit. After the sawing is completed, the steel bar waste is returned to the steel bar waste collection bin 500 through the steel bar cutting unit. S5. The finished steel bars that have been sawn are sent one by one to the subsequent processing steps for further processing.

[0047] In some specific embodiments of this application, the intelligent rebar feeding system can receive sporadic rebar processing orders dispatched by the system at the construction site, and generate a rebar production list by the automatic optimization cutting algorithm software, which is then sent to the PLC control system for automatic production.

[0048] The categorized rebar storage module moves according to the rebar specifications. The working principle of the raw material storage bin 102 is as follows: Figure 4 As shown, multiple raw material storage bins (A~K) are arranged side-by-side on the vehicle-mounted work platform 600, with each bin 102 storing steel bars of different specifications. Position A is the pickup location, and the others are storage locations. For example, to retrieve raw material storage bin 102 at position F, the bin transfer component 103 first moves to position A, then raises the bin 102 and moves it to the empty space at position C for storage (see reference). Figure 4 Steps SY1-SY3 are performed, then the hopper transfer component 103 moves to position F, and the raw material storage hopper 102 at that position is moved to position A (refer to...). Figure 4 Steps SY4-SY6 in the text.

[0049] The number of rebars picked up by the rebar picking unit is determined by the rebar production bill. The rebar transfer unit lifts the rebars and flips them to be fed into the rebar cutting unit. The cut rebars can then be further processed. Finally, the finished products produced according to the rebar production bill are bundled and labeled, and then transported away by tower crane or transfer vehicle, before the next order is scheduled.
