Description

[Detailed description of the invention] The present invention relates to a vehicle transport device.

Traditionally, vehicles have been transported at vehicle inspection and repair factories by either (a) towing the vehicle directly by a towing vehicle, or (b)
This was done by replacing the main truck attached to the vehicle with a temporary truck, and connecting the temporary truck to a conveyor device to move the vehicle. However, in the former case, the towing vehicle comes on the same rail as the vehicle being towed, which not only makes it impossible to freely set the distance between the conveyed vehicles or to freely move other vehicles between vehicles on the same rail. However, it had the disadvantage that it was not possible to automatically transport multiple vehicles at a constant speed. In addition, in the latter case, temporary trolleys for the number of vehicles to be transported at an inspection/repair factory, etc., and trolley exchange equipment between the main trolley and the temporary trolley are required, and there is a drawback that a large amount of manpower is required for the trolley replacement work.
