Abstract

Afin de réduire la place nécessaire au pivotement sur l'axe vertical X du châssis cabine 5 et du bras articulé 4 avec le godet 12 portés par ce châssis, ainsi que pour faciliter les manîoeuvres dans une excavation étroite, l'axe de pivotement vertical Y du bras articulé 4 est placé près du milieu, dans le sens transversal, sur l'avant du châssis cabine. Pour la même raison, l'élément inférieur 10 du bras articulé est courbé pour avoir une forme en boomerang et l'articulation Z entre cet élément inférieur et l'élément porte-godet 11 est située sensiblement au milieu, dans le sens transversal, à la position repliée pour le déplacement de l'engin. (CF DESSIN DANS BOPI)In order to reduce the space required for pivoting on the vertical axis X of the cab chassis 5 and of the articulated arm 4 with the bucket 12 carried by this chassis, as well as to facilitate maneuvers in a narrow excavation, the vertical pivot axis Y of the articulated arm 4 is placed near the middle, in the transverse direction, on the front of the cab chassis. For the same reason, the lower element 10 of the articulated arm is curved to have a boomerang shape and the Z-joint between this lower element and the bucket-carrying element 11 is located substantially in the middle, in the transverse direction, at the folded position for moving the machine. (CF DRAWING IN BOPI)
