PURPOSE: To aim at enhancing the efficiency of container handling work, by providing such an arrangement that a plurality of lock cone fittings for locking containers are arranged on a beam, and a chain wire is successively set onto the rotary shafts of the fittings, and therefore, all fittings may be simultaneously operated and released.

CONSTITUTION: A plurality of lock cone fittings 1A as container locking hardwares are arranged on a beam 7 adapted to be mounted on a ship structure member 9. A chain wire 6 is successively set onto the lock shafts of the fittings so that the chain wire 6 is reversibly rotated along the fittings. When one end of the chain wire 6 is pulled, all fittings may be simultaneously operated and released, thereby the efficiency of container handling work is aimed at being enhanced.
