ABSTRACT:
A power assisted hand truck is disclosed. The hand truck includes a generally vertically extending rack pivotably mounted on a pair of laterally disposed front wheels and having a load bearing member extending from the front side thereof. A frame is connected to the front wheels and extends rearwardly with respect to the rack. The length of the frame in the rearward direction is adjustable, and the frame includes rear wheels on the underside thereof spaced from the front wheels. A bottom actuator is fixed to the frame and mounted so as to control the length thereof. A top actuator extends from the frame to the rack. The bottom and top actuators are operated to project the lower end of the rack forwardly and tilt the rack backwardly to lift a load resting on the load bearing member for transportation with the hand truck. The actuators are operated in reverse to lower the load.
