ABSTRACT:
An articulated cable puller includes a boom assembly having a boom with a sheave positioned thereon. The boom is mounted upon a load beam and is movable between generally horizontal and vertical positions. A rotatable base is positioned upon a vehicle and has a rectangular link pivotally attached thereto. An A-frame is pivotally attached to the top of the link and features a tube attached to its top side. The load beam features downward extending ears that are secured to the tube of the A-frame by a pin. Hydraulic cylinders are connected between the base and the load beam and frame and may be actuated to adjust the positioning of the boom assembly. Hydraulic cylinders are also positioned between the vehicle and the base and are actuated to adjust the position of the base.
