ABSTRACT:
A hand truck having load shifting member which tilts the hand truck under conditions of greater leverage than that available by grasping the frame of the hand truck is disclosed. The load shifting member comprises a spring retracting lever rotatably attached to an axle journaled from the frame of the hand truck such that when in a retracted position, the lever is substantially parallel to the frame. Pulling on the upper end of the lever rotates the lever such that the lower end of the lever engages the lower portion of the hand truck frame, shifting the center of gravity of the loaded hand truck such that it may be more easily tilted to a position for moving the hand truck. A spring returns the lever to a retracted position when not in use.
