ABSTRACT:
A wheel-removing and handling dolly device for dual or single-tired vehicle wheel assemblies consisting of a wheeled base having an upstanding post containing a hydraulic lifting ram cylinder whose piston rod is connected to a carriage assembly slidably engaged on the post. Respective gripping lever arms are provided on opposite sides of the carriage assembly, the lever arms having tire-gripping members horizontally pivoted to their outer end portions adapted to grippingly engaged diametrically opposite portions of a wheel assembly. The inner end of one of the lever arms is operatively connected to a hydraulic clamping cylinder assembly. A hydraulic wheel puller cylinder is carried horizontally by the carriage, extending between the gripping lever arms and having an extensible piston rod provided with a wheel hub-engaging head portion. A manually operated ram pump is carried on the carriage assembly and is connected through respective control valves to the lifting cylinder, the clamping cylinder and the wheel puller cylinder. After a wheel assembly is clamped and pulled from a vehicle, the wheel assembly can be rotated to a horizontal position, providing access to its brake drum or other parts for repair, cleaning or other servicing operations.
