Grapple
The invention relates to grapple for mounting to a boom of a boom crane. The grapple has a body member for mounting to the end of a boom of a boom crane including a first wing member and a second wing member and opposing first and second jaw members. Each jaw is hingably coupled to the body member, and hinges with respect to the body member by the action of a hydraulic cylinder. A first end of the hydraulic cylinder is coupled to the jaw member and a second end of the hydraulic cylinder is coupled to a portion of one of the wing members. The first and second wing members extend to position the second end of each hydraulic cylinder rearward of an end of the boom of the boom crane or a coupling between the body member and the boom of the boom crane.
