TOP PIVOT DOOR/REAR DOOR LATCHES/GATE DELAY
Located at the bottom left, center, and right-hand side of the rear door are the door latches. The latches
lock into the apron chain to hold the door closed when loading. When the hydraulics for the main apron
chain are activated, the latches automatically flip to open with the movement of the apron chains. The
rear door is held open by two hydraulic cylinders. This system allows for a total cleanout of the box.
Upon completion of unloading & switching off the apron chain, the rear door will close and the latches will
automatically lock into the apron chain.
