The Auxiliary Arm consists of a boom mast and arm of Epoxiglas®- construction for mounting on an insulated boom such as the Pitman Polecat®-. The arm is designed for use on light construction when handling multiple conductors. The two-legged mast can be mounted on square or rectangular shaped booms designed to handle 2,000 pounds or more. If boom units of lesser ratings are employed, the lifting and maneuvering application of this unit must be reduced accordingly.
