CA 2514554

A cargo transportation device has a container including a cargo door accessible from the outside for closing the container and being movable from an open position to a closed position. A security system is provided that includes a latching device on the inside of the container, the latching device having a latch, a screw for moving the latch between an open position and a closed position, and a rotary motor for turning the screw. The security system has a latch receiving device, adapted to receive the latch, on the inside of the container. A controller operates a motor to turn a screw in one direction and thereby moves the latch from its unlocked position to its locked position. The controller also can operate the motor to turn the screw in the direction opposite of said one direction thereby moving the latch from its locked position in the latch receiving device to its unlocked position.

L'invention concerne un dispositif de transport de marchandises qui présente un conteneur comprenant une porte de chargement accessible depuis l'extérieur, qui permet de fermer le conteneur et qui peut être déplacée d'une position ouverte à une position fermée. Un système de sécurité est fourni et comprend un dispositif de verrouillage à l'intérieur du conteneur; ce dispositif comprenant: un verrou, une vis permettant de déplacer le verrou entre une position ouverte et une position fermée, et un moteur rotatif permettant de faire tourner la vis. Ce système de sécurité présente un dispositif de réception de verrou, conçu pour recevoir le verrou, à l'intérieur du conteneur. Un contrôleur actionne un moteur afin de faire tourner la vis dans un sens, ce qui permet de déplacer le verrou de sa position débloquée à sa position bloquée. Le contrôleur peut également actionner le moteur afin de faire tourner la vis dans le sens opposé à l'autre sens, ce qui permet de déplacer le verrou de sa position débloquée dans le dispositif de réception de verrou à sa position bloquée.
