ABSTRACT:
A hand truck which includes an automatically adjustable toe plate. The toe plate is attached to the frame of the hand truck in a slidable manner by means of a coil spring. A load placed on the toe plate causes it to move downwardly a predetermined distance. The coil spring may be sized for a particular use depending on the bulk and weight of objects placed thereon such that a predetermined object placed on the toe plate will cause its movement downwardly a predetermined distance in order that the top of any object or stack of objects located on the hand truck is at a level above the ground which is convenient for an operator thereof to load and unload the hand truck without the necessity of bending in order to place objects onto or remove them from the hand truck.
