ABSTRACT:
A mandrel is provided with a lifting eye at its upper end for coupling to a hoist and diametrically opposite extending lifting lugs at its lower end. A socket member having a diametrically elongated bore passing completely through the socket member is arranged to be secured in the top surface of a weight to be lifted with the top surface of the socket flush with the top surface of the weight. The socket includes a transverse channel on its bottom end extending at right angles to the diametric elongation of the socket bore. The mandrel can be lowered through the bore with the lugs passing through the diametrically opposite elongated portions and thence rotated 90.degree. after the lugs clear the bottom of the socket, the lugs then being received in the transverse channel. Springs serve to bias the mandrel and lugs upwardly relative to the socket to assure proper seating.
