<p>A cargo hook 10 suitable for carrying a load comprising a housing 20, a load beam 30 which is mounted to the housing and is moveable relative to the housing 20 between a closed position and an open position, a latch mechanism 40 with a locked condition that locks the load beam 30 in the closed position and an unlocked condition that allows the load beam 30 to move from the closed to open position and a moveable stop 70 which engages with the latch mechanism 40 and has a first position that prevents the movement of the latch mechanism 40 from the locked condition and a second condition which permits movement from the locked condition to the unlocked condition. The moveable stop 70 effectively provides a safety lock for the latch mechanism 40. The moveable stop 70 automatically adopts the first position when a load greater than or equal to a specified value is carried by the load beam 30 and adopts the second position when no load or a load less than a specified value is carried. The moveable stop 70 may also be deployed manually. This device is suitable for use with loads underslung beneath a helicopter.</p> |
