Abstract

Selon un mode de réalisation, cette excavatrice comprend une structure de base; une flèche portée de façon pivotante, à son extrémité inférieure, par la structure de base; un bras porté de façon pivotante, près de son extrémité intérieure, par l'extrémité supérieure de la flèche ; et une benne à demi-coquilles suspendue à l'extrémité extérieure du bras par des systèmes à poulies et à câbles qui se prolongent le long du bras et de la flèche de façon à faire qu'une plus grande partie des câbles soit fournie aux parties placées entre l'extrémité intérieure du bras et la benne au fur et à mesure que la flèche s'incline vers le bas.
