Abstract

A vertically stored dockboard. The dockboard includes a frame or supporting structure which is mounted on a loading dock and a rap or deck plate is hinged at its rear edge to the frame and is movable between a generally vertical storage position and a horizontal operating position where the ramp bridges the gap between the loading dock and a truck parked in front of the dock. The ramp is moved upwardly to the vertical storage position by a hydraulic cylinder mechanism and is locked in the storage position by a toggle assembly. As the ramp is moved upwardly to the vertical storage position, the toggle assembly will be automatically moved to an over-center position to lock the ramp in the storage position. The toggle assembly can be released by a manually operated toggle release arm to enable the ramp to fall by gravity to the horizontal storage position.
