Abstract: A hook with a latch and trigger mechanism assembly. The assembly includes a hook having a body and an open saddle. A latch is pivotable between a closed position and an open position. A finger handle extends from the body. A finger trigger entirely within a space between the finger handle and the body is movable between a closed rest position and a retracted position permitting movement of the latch to the open position.

Abstract: A shackle with captured pin assembly. The shackle includes a pair of opposed legs. A first ear for one of the opposed legs includes an opening therethrough to receive a shackle pin. A recess in the opening receives a spring clip surrounding a shaft of the shackle pin. A second ear for another of the opposed legs is opposed to the first ear. The second ear has an opening therethrough to receive the shackle pin and has an opening with a threaded portion. The shackle pin has a head, a threaded portion engageable with the threaded portion of the second ear opening, and a reduced diameter portion. The rotating retaining clip rotates about an axis parallel to the shackle pin between a locked and an unlocked position.

Abstract: A retaining pin assembly for a lifting system which includes a hook prong and a hook cam. The retaining pin assembly includes at least one lock arm assembly having a first end with at least one aperture which aligns with an opening through the hook cam and having an opposed second end with at least one aperture which aligns with an opening through the hook prong. A hook cam retaining pin has a head and has a shaft passing through the hook cam opening and the lock arm first end aperture, wherein the shaft has at least one groove therein parallel to the axis of the shaft. A retaining ring surrounds the hook cam shaft, the retaining ring having at least one inwardly extending tab received in the shaft groove in order to retain the pin in the lock arm. A recess in the lock arm receives the retaining ring therein.
