ABSTRACT:
A motor driven tiltable cargo deck includes a support frame having a pair of opposed sides, a first end and a second end. A first pair of sprockets are mounted to the opposed sides adjacent the first end of the support frame. A second pair of sprockets are mounted to the opposed sides adjacent the second end of the support frame. A pair of continuous chains are rotatably mounted between the first pair of sprockets and the second pair of sprockets. A deck is provided having a first end and a second end. The deck is supported by the support frame and slidably movable from a travel position in which the first end of the deck is adjacent the first end of the support frame to an unloading position in which the second end of the deck rests upon a groundsurface. A pair of linkage arms are provided having a first end and a second end. The first ends are pivotally mounted to the deck adjacent the first end. The second ends are attached to the pair of chains such that the deck moves relative to the support frame upon movement of the chain. The linkage arms exert a resisting force upon the first end of the deck as the second end of the deck is lowered. A drive motor is provided for rotating one of the first pair of sprockets and the second pair of sprockets, thereby rotating the chain to effect movement of the deck relative to the support frame.
