ABSTRACT:
An elevator platform is mounted by means of lift arms and parallel arms to a frame mounted under the truck bed. On the frame, the normal pivot axis for the parallel arms is aligned vertically above the pivot axis for the lift arms; and the pivot axes on the platform are similarly vertically aligned when the platform is in the horizontal load position. One of the parallel arms is articulated having an elbow intermediate its ends; and a control strut is mounted on the truck to be swung into engagement with the articulated arm adjacent to its elbow while the platform is being raised from the ground position. When so engaged, the proximal link of the articulated arm is locked against further upward movement, so that further upward movement of the lift arms will cause the gate to rotate upward 90.degree. to a vertical storage position behind the truck bed. The frame pivot for the other parallel arm is mounted on an oscillating bracket, allowing that pivot to move to permit the rotation of the platform. The control strut and articulated arm are locked together to prevent downward movement of the gate until the lift arms are again actuated to effect rotation of the platform back to the horizontal load position.
