Abstract

A dock leveler has a frame mounted at a dock, a deck pivoted at one end to said frame and a lip pivotally attached to said deck at the other end thereof. The deck is movable between a first operable position where the deck is substantially horizontal and the lip extended, a second operative position where the lip hangs pendant and the deck is declined and an inoperative position where the deck is substantially horizontal and the lip hangs pendant. A barrier is mounted to have a raised operative position protruding above the deck and an inoperative position flush with the deck. A mechanical linkage automatically raises the barrier when the deck is in the inoperative position and permits the barrier to be lowered to its inoperative position when the deck is in either operative position. The linkage is responsive to both movement of the deck and the position of the lip.
