Abstract: An unloading device having a frame transversely supportable on a pair of spaced side walls of a truck bed is longitudinally movable from the front to the rear of the truck bed. A plurality of wheels secured to the frame and engagable with the side walls facilitate movement of the device. An electric motor or hand crank is drivingly connected to a main shaft mounted on the frame for rotating the shaft in opposite directions, and an elongated sheet of material, such as reinforced nylon, having one end thereof secured to the shaft and the other end thereof secured to the rear of the truck bed is used for receiving an article for transportation. Rotation of the shaft in one direction winds the sheet of material on the shaft, moves the frame toward the rear of the truck bed and shifts the article on the sheet from the front of the truck bed to the rear and off of the truck bed. A rail is mounted on each of the side walls of the truck bed for guiding the wheels.
