[0002] During the manufacturing process of the body in white, it is necessary to install four doors, front cover, rear cover, fenders, fender brackets and other structures at the adjustment line. In this process, a lot of hoists are needed. In order to realize the automatic forward and backward movement of the hoists, a motor drive mechanism is added to improve the work efficiency of the operator.

[0003] In the related technology, usually, the motor drives the walking wheel through the chain sprocket to achieve walking on the guide rail, and the cylinder is ventilated to ensure the contact force between the walking wheel and the guide rail to prevent the walking wheel from slipping, thereby driving the related structure to slide in the horizontal direction. This type of equipment is currently a driving method that is widely used by vehicle manufacturers.

[0004] With respect to the above-mentioned related technologies, the load borne by the suspension wheel cannot be symmetrical on the left and right, resulting in severe friction between the suspension wheel and one side of the guide rail, severe wear of the guide rail and the wheel, which is not conducive to the subsequent related operations of the operator.
