ABSTRACT:
In a side-pull hoist ring having a load carrying ring, a clevis pivotally supporting the load carrying ring for rotation about a first axis and a post assembly extending through the clevis and fixedly engageable with a threaded bore on a load for allowing 360.degree. rotation of the clevis about a second axis generally perpendicular to the load. The post assembly includes a lower support bushing with a large diameter lower load bearing flange and a bolt receiving passageway coaxial with the second axis; a bolt extending through the passageway into the threaded bore of the load where the bolt has a head carrying an upper flange member coacting with the lower flange to capture the clevis and a shank. There is a first cylinder groove in the passageway and a second cylindrical groove around the shank. The grooves are axially aligned when the lower flange and the upper flange capture the clevis. An arcuate spring element having a collapsed shape generally retained in the second groove and a relaxed shape bottomed out in the first groove and extending between the first and second grooves prevents non-destructive axial removal of the bolt from the bushing. The clevis is formed from extruded steel, bar stock or a steel plate.
