Abstract
A tolley for supporting a wheel of a vehicle so that the vehicle may be driven or moved without the wheel touching the ground. The trolley has a hinged frame equipped with three or more wheels, a drive-on part which tilts upward when a wheel is driven onto the trolley and which then supports the wheel from behind, and a front support member. The front support member may be locked in place after the wheel has come to rest on the trolley. The trolley may be folded for storage.
