ABSTRACT:
The present invention is an extension assembly for use in combination with a handtruck which includes a load plate having a load carrying surface, a side rail assembly extending upwardly from and in mechanical communication with the load plate, and a pair of wheels in mechanical communication with the side rail assembly. The unload assist mechanism includes a push plate positioned above the load plate, the push plate having a load engaging surface extending substantially perpendicular to the load carrying surface. An extension assembly in mechanical communication with the handtruck and push plate, moves the push plate between a loading position and an unloading position while maintaining the perpendicular orientation of the load engaging surface with respect to the load carrying surface.
