ABSTRACT:
The specification discloses various embodiments of apparatus adapted to function as convertible wire rope load binders, container lashing or pullers. All embodiments utilize a wire rope clamp of the type which grips the wire rope on tensioning of the wire rope, and a threaded tubular extension coaxial with the rope pass line, in combination with a slack take-up device, which may be any of a variety of slack take-up devices threaded onto the tubular extension. A preferred embodiment employs a slack take-up device in the form of an over-center or toggle lever and a sheave device attached to the body of the clamp. Another embodiment employs a combined hook and clevis device having a screw connection to the body of the clamp. Another embodiment utilizes a winch device on the tensioning end of the wire rope to provide for tensioning the wire rope. Another embodiment employs a rectangular frame surrounding the body of the clamp, the frame having an opening through which a threaded tubular extension on the clamp body extends. A nut on the tubular extension cooperates with the frame to adjust the body of the clamp in relation to the frame.
