Abstract
A hoist assembly for overhead lifting including an upwardly extending attachment member, a downwardly depending shank coupled to the attachment member and having a polygonal cross sectional shape, a hoist body coupled to the downwardly depending shank, and a plate positioned between the upwardly extending attachment member and the hoist body, that defines a first circular aperture that matingly receives the polygonal shank and a second polygonal aperture laterally spaced from the first circular aperture. The plate is moveable between a first position, in which the polygonal shank extends into the first circular aperture, and a second position, in which the polygonal shank extends into the second polygonal aperture. Rotation of the attachment member with respect to the plate is permitted when the plate is in the first position, and rotation of the attachment member with respect to the plate is inhibited when the plate is in the second position.
