ABSTRACT:
A vehicle arranged for raising and lowering the frame relative to the ground wheels for loading comprises a vehicle frame with a hitch at a forward end of the frame and at least two ground wheels for supporting the frame for movement across the ground. Each wheel has a mounting assembly providing driven rotation of a hub carrying the wheel spindle from a raised height of the wheel to a lower locked position. The hub has an internal gear which is driven by a hydraulic motor driving a pinion. The hub can rotate through 180 degrees from a top dead canter to a position just beyond bottom dead center where it engages a stop to support vertical loads. Twisting of the hub and a parallel support plate are prevented by interlocking the members at the bottom position.
