Abstract

Excavateur à bras articulés. L'excavateur selon l'invention comprend une plate-forme pivotante 16 qui porte, par l'intermédiaire de deux bras articulés 24 et 48, un godet renversé; les moyens pour commander le déplacement angulaire du premier bras 24 comprennent : un vérin 28 articule à une extrémité 30 sur la plate-forme 16 au voisinage de l'axe d'articulation du premier bras 24 et deux leviers 38 et 40 articulés l'un sur l'autte autour d'un axe 36 sur lequel pivote également l'autre extrémité 34 du vérin 28. Permet la réalisation d'excavations profondes juste à proximité de l'excavateur.
