  • Patent number: 6086313
    Abstract: The Dual Pull Open Bottom Portable Pickup Truck Trailer Unloader System is an unloader device that facilitates the easy removal of material from trucks and trailers by the means of hand power or electric or hydraulic motor drive. The open bottom permits the material to slide along the bottom of the truck to either fall directly on the ground when operated or to be slid to the back of the vehicle to be unloaded by hand or by equipment. The dual pull chain, cable, rope or strap system creates an even pull on the unloader box to prevent binding from unevenly distributed loads in the vehicle's cargo space and inside the U-shaped unloader box. This adaptable system with an open bottom, back board and side boards is a sliding mechanism that can be custom-made to fit specific design requirements. The size of back board and size and height of side boards are determined by the specific requirements of each unloading application.

The basic embodiment is that of a tray like formation of substantially rectangular configuration, including a special universal bifurcated mounting-bracket located substantially perpendicularly beneath the tray, and preferably as two such brackets arranged inline at substantially opposite ends of the tray undersurface, so as to facilitate a simple stable attachement.
