A trailer assembly for carrying coiled tubing includes a main beam assembly extending from a forward end of the trailer assembly to a rear end of the trailer assembly. The main beam assembly includes a forward portion that extends from the forward end of the trailer assembly, a rear portion that extends to the rear end of the trailer assembly, and a middle portion connected between the forward portion and the rear portion and configured to transfer load to the forward portion and the rear portion. The middle portion includes an upper beam section, and a lower beam section vertically separated from the upper beam section. The upper beam section is configured to share a load resultant from a bending force experienced by the lower beam section.

A riding lawn mower having an adjustable cutting width has at least one front wheel, a plurality of rear wheels, a frame extending from the at least one front wheel to the plurality of rear wheels and a plurality of cutting decks, each cutting deck comprising a cutting blade. A motor is supported by the frame and configured to drive the cutting blades of the cutting decks. A support configured to couple the cutting decks to the frame. The support is configured to extend at least one of the cutting decks laterally from beneath the frame to adjust a cutting width provided by the blades.

The present application provides a chassis, a vehicle, a device for manufacturing a vehicle and a method for manufacturing a vehicle. The chassis includes at least two movable bodies that are continuously arranged along a first preset direction, and by adjusting a position of at least one movable body in the first preset direction, a length of the chassis in the first preset direction can be changed so as to enable the chassis to adapt to the vehicle body of a different length. Since each movable body is provided at an adjacent movable body thereof with a position adjustable in a preset direction, the chassis is made into a telescopic structure that is adjustable in length. The length of the chassis can be adjusted according to the requirements to enable the chassis to adapt to the vehicle body of a different length.

The present disclosure is related to an electric pallet truck. The electric pallet truck includes a frame, a lifting unit, and a walking unit. The lifting unit is configured to adjust a height of the frame. The walking unit is configured to drive the frame to move. The lifting unit includes a lifting mechanism fixedly connected to the frame and a hydraulic mechanism configured to control a lifting of the lifting mechanism. The walking unit includes a driving mechanism configured at a bottom of the lifting mechanism.

A U-shaped support frame has a base beam and parallel side beams extending rearward from the base beam and defining an open implement area, which can be made adjustable. A hitch is attached to the front end of the support frame and frame wheels support the side beams, and rotate about a horizontal frame wheel axis that is fixed in an orientation perpendicular to the operating travel direction. Implements are configured to perform an implement operation and to rest on the ground surface when in an idle position. The support frame is moved rearward to a loading position where each implement is movable to an operating position supported by the support frame. Each implement provides a beam lock connection between the side beams that resists twisting movement of the side beams to maintain the frame wheels and the side beams in a substantially fixed relationship with respect to each other.

A system and method for controlling a vehicle, where the system includes independent driving modules each including a connection device having a rotation center spaced apart from a driving shaft in a forward/rearward direction and configured to connect the wheel and a vehicle body to move the wheel in the forward/rearward or an upward/downward direction, a shock absorber extending in a longitudinal direction and configured to contract or stretch, to connect the vehicle body and the connection device, and to restrict an upward/downward movement of the connection device, and a driving device configured to rotate the wheel, a road surface detector configured to detect a height displacement or a state of a road, and a controller configured to control velocities of the front and rear wheels of the independent driving modules, and to change a height of the vehicle based on the height displacement or the state of the road.

An on-board electronics system of an aerial work platform moves the wheels between a retracted and extended position by pivoting a respective arm. The method comprises the following successive steps: a) orienting each wheel tangentially to the pivoting path of the corresponding arm, b) moving the wheel by pivotally actuating the corresponding arm, and c) reorienting the wheel so as to enable another translation of the aerial work platform. The steps are performed in different orders between the wheels so that at any time at least one of the following conditions is complied with: —the brake system of at least one wheel is active, —at least one wheel is rotated by a motorised drive, —the orientation of the wheels relative to one another prevents any translation of the aerial work platform (1) on the ground as a result of gravitational force.
