ABSTRACT:
An articulated arm for excavator vehicles is described, which is able to make excavations lateral to said vehicles and parallel to the travelling direction thereof. The main characteristic of said arm is that it possesses two articulated joints which enable it to move the excavating bucket in a plane parallel to the plane in which said arm lies, thus obtaining lateral excavations with perfectly parallel walls perpendicular to the working floor.
