The lifting ring comprises a shoulder shaft 1 on whose threaded body 2 is screwed and secured by bonding a flange 3. A crosshead 4 swivels freely on the body 2, being retained between the inner face 5 of the flange 3 and the underside 6 of the head 7 of the shaft 1. On each side trunnion 8,8' of the crosshead 4 swivels one jaw 9,9' of a shackle 10. Each jaw 9,9' is retained on its trunnion 8,8' by a ring 11 of circular section that is partly engaged in a groove of semi-circular section in the outer wall of the trunnion. For safety reasons, the lifting ring is designed not to permit disassembly.
