Abstract
A locking mechanism has a guide and a vertically movable plate. The plate is movable in the guide under gravitational influence between a locked position and an unlocked position. A slot is formed in the plate to receive a guide pin. The guide pin maintains the movable plate in the guide. The slot enables axial vertical movement of the plate in the guide. The plate moves into the locked position upon contact with a surface. In this position, the plate projects from the guide to lock a roll off container onto the hoist. The movable plate reverts to the unlocked position upon removal of the surface so that the plate moves into the guide.
