Abstract

A suspension hook assembly for a hoist in which the shank of the hook is received between an assembled pair of half-cylindrical members held together by a ring. A pin member received between spaced frame members of the hoist extends through aligned holes in the assembled half-cylindrical members, and the ring is positioned axially between the pin and outwardly directed projections formed on the half-cylindrical members. The hook then pivots about a first axis through its shank, and the hook assembly pivots about a second, perpendicular, axis through the pin.
