ABSTRACT:
A truck deck with ground level loading/unloading position includes guide tracks supported by a support frame. Guide members consisting of pivotally connected sections are telescopically received in the guide tracks. A load platform is supported by and slidably movable in relation to the support frame. A first pair of chains pull the load platform and extend the guide members. When the guide members reach a fully extended position with the majority of the weight of the load platform past the pivot axis, they pivot and thereby guide the movement of the load platform in a downwardly direction onto a ground surface. A second pair of chains lift the load platform from the ground surface and move it along guide members until the guide members pivot to a substantially horizontal position. The second pair of chains then pull the load platform and the guide members back into a retracted position.
