ABSTRACT:
A horizontal load carrying pin is rotatable on a horizontal pivot and has a free end supported on a saddle on a latch arm which may be withdrawn to release the load. Upon release of the load a counterweight on the opposite end of the pin returns the pin to horizontal position. The latch arm is spring opened and held in closed position by a pawl which may be released by a remote controlled fluid pressure cylinder and piston or by a manually operated lever in the housing of the hook. The load carrying pin is of generally cylindrical shape to carry flat web type slings as well as steel rings.
