ABSTRACT:
Apparatus for stopping and holding a rope is disclosed. The apparatus includes a power drum, a wind up mechanism having two small drums and an air operated chain drive system between the power drum and the wind up mechanism. A rope is threaded through the apparatus such that the rope passes between the two drums of the wind up mechanism and is wrapped once around the power drum. When the chain drive system is not energized, the rope is free to move in either direction through the apparatus; however, when the chain drive system is energized, the rope is wrapped around the two small drums of the wind up mechanism and is thereby stopped and held under tension from further pay out through the apparatus.
