ABSTRACT:
A gate latching mechanism comprising a gate for closing the mouth of a hoist hook. The gate is attached to the hook and pivotally movable out of the mouth of the hook about a substantially vertical pivot axis spaced from the central axis of the stem of the hook. A spring which is located at the pivot axis biases the gate to swing to an open position. The free end of the gate is provided with a latch which, when closed, covers the tip of the hook, a lock which holds the latch engaged with the tip until the lock is manually released, and a locking spring for moving the lock to the locked position when the latch is moved to engage the tip.
