CA 2541238

The inventive backboard bar for a dumping body comprises a support which has a contact surface, is fixed to the backboard and provided with means for adjusting the distance between said contact surface and the backboard. Said backboard also comprises a pivotable hook which is provided with a projection corresponding to the contact surface of the support, a first pivotable element and a second pivotable element connecting the first element to the hook. An actuator is connected to the first element. The activated actuator transmits a rotation motion to the first element. Said first element retransmits said motion to the second element and to the hook which turns between a first position wherein the hook projection abuts against the contact surface of the support, thereby preventing the backboard from opening and a second position wherein the hook projection is released from the support, thereby enabling the backboard to open.

Une barrure de porte arrière d'une benne basculante comprenant un appui ayant une surface de contact. L'appui est fixé sur la porte et comprend un moyen d'ajustement d'une distance entre la surface de contact et la porte. La barrure comprend en outre un crochet pivotable ayant une projection correspondante à la surface de contact de l'appui, une première membrure pivotable et une deuxième membrure pivotable reliant la première membrure au crochet. Un actionneur est relié à la première membrure. L'actionneur lorsque activé transmet un mouvement de rotation à la première membrure. La première membrure retransmet ce mouvement à la deuxième membrure et au crochet qui est tourné entre une première position dans laquelle la projection du crochet s'appuie sur la surface de contact de l'appui, empêchant une ouverture de la porte, et une deuxième position dans laquelle la projection du crochet est dégagée de l'appui, permettant l'ouverture de la porte.
