<p>This particular invention relates to a self-locking device for interlocking superposed stacked containers, particularly on the deck of ship or on a platform, during transportation, comprising a lock housing (1, 1') in which a vertical shaft is rotatably mounted when in use. The shaft has an upper portion with an upper locking device (2, 2') located outside the lock housing and a lower portion with a lower locking device (3, 3') located outside the lock housing. On shaft (9, 9') is fixed a carry-out (5, 5') by means of which the shaft can rotate. Furthermore, the lock housing comprises a hydraulic unit (4, 4') with a primary piston (7, 7') and a secondary piston (8, 8') fixed to be able to effect the above-mentioned carry-out (5, 5'). Thus the primary piston is fixed to be effected by the weight of the container when lowering it to the underlayer so that the said locking devices (2, 2', 3, 3') are automatically turned into locking position through the above-mentioned secondary piston and carry-out.</p> |
