  • Integrated corner casting locking mechanism for shipping containers
    Patent number: 7014234
    Abstract: A system for locking and unlocking containers to transport modes and other containers comprises a plate and spring housed in an upper corner fitting of a container, a cable connected to the plate, and guides to route the cable from the plate to a rotatable locking leg housed in a lower corner fitting of the container. The twist lock of a lifting spreader engages the upper corner fitting of a container, urging the plate and spring in the upper corner fitting downward. The cable is pulled downward by the depression of the plate, accordingly pulling the locking leg, causing it to rotate to an unlocked position.
