A chain puller for use in marine salvage that includes a chain pulling platform having linearly disposed first and second chain stoppers. Each chain stopper includes a pair of pivotal doors that permit the passage of a chain in one direction while stopping the action of a chain moving in the opposite direction. The action on the pivotal doors uses gravity for vertical alignment. The pivotal doors are spaced apart the distance of a vertical chain-link in the static position and are pivotally spread apart to permit movement of the chain in one direction in the dynamic position.
