ABSTRACT:
A hoist ring assembly for transporting loads, including an anchor bushing that is threaded into the load and forms the pivot for a releasable swivel hanger assembly with a shackle connectable to an overhead hoist. The swivel hanger is quickly attachable to and detachable from the anchor bushing to expedite load movement. The hanger swivels on the anchor bushing in a side-pull action and has a key hole slot that hangs the anchor bushing during use and permits the hanger to be rapidly removed from the anchor bushing when the hoist is slack. A latch lever holds the hanger in its attached position on the anchor bushing when unloaded and is quickly flipped out of the way for swivel hanger removal.
