  • Patent number: 6494515
    Abstract: The pole handler attachment includes a base frame that is pivotally attached to an arm of an earth moving machine for pivotal movement about a transverse horizontal axis. A trunnion is fixed to the base frame. A sleeve is journaled on the trunnion for pivotal movement about a trunnion axis that is normal to the transverse horizontal axis. A fixed clamp assembly is fixed to the sleeve. A movable clamp assembly is pivotally attached to the sleeve. A clamp cylinder pivots the movable clamp assembly to hold a pole against first and second clamp surfaces on the fixed clamp assembly. The first clamp surface is perpendicular to the second clamp surface. A tilt linear actuator pivots the sleeve on the trunnion.
