A bearing device comprising a hook, housing, and latch and release mechanism for locking and unlocking the hook, the lock and release mechanism having a pivot latch with a lower cavity capable of receiving one end of the hook, a lever and a locking cam. The lever is pivotally mounted in the housing and has first roller and second rollers on the ends thereof, the latch has an upper cavity in which the first roller can rest and roll, the cam has at least one locking arm on which the second roller can rest and roll. A rotation of the cam in one direction causes the lever to tilt in the other direction, releasing the first roller from the latch, and causes the latch to pivot under the weight of the hook until the end of the hook is released from the lower cavity in the latch.
