Abstract
A rear loading system for vehicles where a platform (16) is raised from the ground to a position level with the tray (2) of the vehicle. Typically the platform is raised by turning handle (32) which turns a shaft hidden in frame member (20) of U-shaped frame (4). The shaft in turn rotates a sprocket of an endless chain hidden in frame member (22). All four lifting cables (18a-d) run over pulleys in the U-frame and are attached to the endless chain so that on turning of the handle all of the cables are pulled by exactly the same distance and the platform rises in a horizontal attitude. When level with U-frame (4) the platform (16) can be locked thereto and frame and platform can be pivoted to a vertical position to act as a tail gate.
