Abstract:
A hoist ring assembly with expansion anchor includes an anchor subassembly and a rotatable and pivotable lifting loop. The anchor subassembly includes a bushing element, an engagement element and a retainer element. The bushing element has an anchor shaft extending along a major axis. The engagement element has a threaded bore extending long a bore axis which is approximately parallel to the major axis when the assembly is in assembled state. The threaded bore is adapted to threadably receive a threaded portion of the retainer element. The bore axis may be forced out of alignment with the major axis by way of a tightening rotation of the threaded portion with respect to the threaded bore, thus expanding the effective diameter of the combined anchor shaft and engagement element. The assembly is thereby releasably anchorable to a pre-drilled hole in a load to be lifted.
