ABSTRACT:
A modified hand truck with a novel structure that optimizes the cooperation between the carrying platform and the wheels in order to produce the maximum lifting force possible for the operator. The wheels are free to move in relation to the carrying platform, thus tilting of the load to the extent desired is possible before lifting becomes necessary. In addition, because the invention minimizes the impact of the size of the wheels on the lifting action, large wheels are used to improve the rideability and stability of the truck.
