Abstract
This invention relates to a security system aimed at closing and locking a cover of an opening of a tank trailer to avoid any tampering of its content and to prove that the content of the tank has not been tampered. The security system comprises a locking member movable between a lock position to prevent the opening of the cover, and an unlock position to allow the opening of the cover. The invention also comprises an actuating device mounted to the tank trailer operatively connected to the locking member for moving it between the lock and the unlock positions. A sealing mechanism engages the actuating device when the locking member is in the lock position to prevent any movement of the locking member. The sealing mechanism comprises a breakable indicator which is broken upon disengagement from the actuating device, thereby indicating that the openable cover has been tampered with.
