Abstract

L'invention concerne une benne basculante comportant un caisson de chargement (10) monté pivotant sur un châssis (2) de véhicule. Une porte (12) formant une paroi latérale du caisson de chargement et s'ouvrant au niveau de son bord inférieur comprend un corps de châssis extérieur (15) comportant une structure d'ouverture en bord inférieur et un corps de porte (16) doté d'une structure d'ouverture latérale conçue pour fermer l'espace intérieur du corps de châssis extérieur (15). La benne basculante comprend un mécanisme de verrouillage de type à libération automatique (30) conçu pour retenir le corps de châssis extérieur (15) lorsque le caisson de chargement (10) est abaissé et pour libérer automatiquement le corps de châssis extérieur (15) lorsque le caisson de chargement (10) est incliné. La benne basculante comprend en outre un mécanisme de verrouillage inverseur (40) comportant des éléments de verrouillage (41, 42) montés sur un corps de porte et verrouillant celui-ci, un élément de verrouillage (43) monté sur le corps de châssis extérieur (15) et verrouillant celui-ci, un élément support (44) monté sur le corps de châssis extérieur (15), et une poignée-levier (45) supportée par l'élément support (44) et susceptible d'enclencher sélectivement les éléments de verrouillage (41, 42) ou l'élément de verrouillage (43). L'invention permet de faciliter le chargement et d'assurer un déchargement particulièrement efficace grâce à la structure d'ouverture en bord inférieur de la porte (12). Les opérations de verrouillage et de déverrouillage de la porte sont également facilitées.
