20100176614RELEASABLE LIFTING LINK - A lifting link for anchors embedded in concrete panels is disclosed having a shackle with a recessed cross bridge. A part circular latch rotates within a chamber of a hollow toroidal ring. The chamber has a circular longitudinal axis. The upper portion of the ring is formed into a U-shaped slot through which a handle of the latch rotates. A transverse slot accepts the head of anchor. The shackle bears against the exterior surface of the U-shaped slot. The radius of curvature of the exterior surface has a centre which is not coincident with the centre of the radius of curvature of the chamber axis. Thus the centre of lift of the shackle is worked away from the adjacent surface of the concrete panel, thereby saving the surface from damage during lifting.07-15-2010
