Abstract
An omni-positional hoist ring wherein a shackle member is pivotally attached to a rotationally mounted lift body, the lift body is rotationally mounted on a flanged bushing, and the flanged bushing is mounted on a screw. Torque is applied to the screw by applying force to one or more axially projecting lugs. The lugs may be positioned on a collar that surrounds and is keyed to a mounting stud, or to a bar nut that is located on the distal end of mounting stud. A boss may be provided surrounding the axial bore of the collar. The purpose of the boss is to space the lifting fixture away from the axially projecting lugs on the radially outer periphery of the collar. When the axially extending lugs are on the outer periphery of a collar, torque is conveniently applied by striking the upstanding lugs with, for example, a hammer. Lugs on a bar nut a conveniently positioned to receive torque from a bar that is projected laterally between the lugs.
