Abstract:
1. In combination with means comprising at least one elongated boom mounted for movement between at least a partially reclined position and an elevated position, said boom supporting a movable frame support member at a distal end thereof and actuator means for moving said boom and for moving said frame support member with respect to said boom, an apparatus mountable on said support member, said apparatus comprising: a frame including an elongated tubular beam member connected to said frame support member; pole grasping jaw support members mounted on said frame for supporting opposed pole grasping jaws for movement relative to each other between pole grasping and non-grasping positions; an actuator connected to at least one of said jaws for moving said one jaw relative to the other for grasping and releasing said pole wherein said apparatus may be moved between a reclined position of said pole and an erect position of said pole by movement of said boom and by movement of said frame support member relative to said boom; and a counterweight beam supported on said frame and including counterweight means supported at a predetermined position thereon for counteracting forces exerted on said apparatus, wherein said counterweight beam is telescopically received within said tubular beam member and is selectively positionable with respect to said tubular beam member for varying a counterweight moment acting on said frame.
