Hand truck with detachable power unit

Abstract

A hand truck has a movable load platform that can be driven upwards and downwards by driving means associated with a readily detachable power unit. This allows an operator to place the hand truck on the ground adjacent a delivery truck, to raise the movable load platform so that it is level with the load bed of the delivery truck, to transfer a heavy package from the delivery truck to the hand truck, and then to lower the elevatable platform so that the loaded hand truck can be pushed across the ground. In addition, the detachable power unit provides a continuous track for urging the hand truck up or down stairs. The track preferably includes a plurality of step engaging members that are sized to firmly engage each tread of a set of stairs so the device is sure-footed.
