MULTIPLE POSITION HOOK ASSEMBLY ABSTRACT OF THE DISCLOSURE: A hook assembly usable with conventional load lifting equipment has a frame and a generally arcuate hook member pivotally assembled to the frame. The hook member is rotatable relative to the frame between an open position for engagement of a load loop, such as a link or sling, a closed position to secure the load for handling, and a discharge position for dropping the load loop from the hook assembly. The frame has a contoured portion fashioned to cooperate with a hook member tip and body portion to define a closed, load retaining eye when the hook member is in the closed position, and an open, unobstructed throat when the hook member is in the open posi- tion. A releasable lock mechanism is assembled with respect to the frame and is operable to hold the hook member in an open position, to lock it in the closed position and to release to allow the hook member to move to the discharge position. The releasable lock mechanism includes a locking member fixed for guided movement relative to the frame. An interior end of the hook member has a plurality of projections defining bearing shoulders engageable with the locking member to lock the hook member in the selected open or closed position. Forces securing the locking member against unlocking are directly proportional to the load on the hook; and the hook member can be remotely released to drop the load loop by setting the load down at a remote location to remove the load from the hook.
