Abstract

To allow of an excavator being able to dig a vertically walled trench in sloping ground the excavator tool-carrying arm of the excavator is in two parts that are pivotal connected about an axis at right angles to the axis about which the bucket and the arm-carrying boom mounted on the mobile base of the excavator are connected to the opposite ends of the arm.
