  • Patent number: 4118059
    Abstract: The storage of pipes hoisted by means of a wire-rope sling tightly noosed around the pipes to form a pipe bundle is facilitated by clamping the rope in the sleeve of the sling choker to lock the tight noose against loosening when the pipe bundle is deposited on a support and is connected from the hoisting means. The sleeve bore is of generally keyhole section. The rope is a sliding fit in the part-cylindrical portion of the bore so as to be locked in said portion and project laterally into the adjacent channel portion of the bore. By force-fitting a pin into the channel portion in which the pin is a sliding fit, the rope length in the bore is clamped against the part-cylindrical portion of the bore.
