ABSTRACT:
An improved structure hoist-use base hoisting ring comprised of a U-shaped clevis movably suspended from the two sides at the lower end of a cylindrical base mount as well as a circular top mounting bushing at the upper section and a bottom mounting bushing at the center section having an upwardly projecting neck and a passageway that are situated over the top and bottom lateral surfaces of a bore through the interior portion of the cylindrical base mount, enabling the installation of a bolt into the top mounting bushing center section and downward through the bottom mounting bushing and the fastening and positioning of its threaded section into the threaded hole of a weight at the lower end. Among the features of the present invention, an annular recess is disposed along the top surface and center section of the cylindrical base mount that provides for the nesting of a flat planar bearing. The center portion opening of the planar bearing is sleeved over the periphery of the neck of the bottom mounting bushing such that its top surface is against the circular top mounting bushing bottom side, enabling the lifting of the load of the weight at the bottom end of the hoisting ring. Since the planar bearing so postured has active rotating capability, the hoisting ring lifting the weight has convenient operation that is adjustable and freely rotatable.
