ABSTRACT:
A dolly for lifting one end of a vehicle and for towing the vehicle includes a pair of identical tandem wheel assemblies interconnected by a pair of spaced parallel steel tubes. At least one of the wheel assemblies includes a hydraulic piston which, in spreading one pair of arms on crank members coupled to the wheel assemblies, forces together the second pair of arms. The ends of the spaced parallel steel tubes are coupled into sockets on the ends of the second pair of arms so that their forcing together operates to lift a vehicle whose tires are resting across the steel tubes. The invention includes means for locking the tubes in their raised position and further includes vehicle wheel locking plates that are actuated by the lifting process.
