Abstract:
A wire pulling assembly for pulling a wire carrying tooling through an underground environment. The pulling assembly includes a cyclical vise carried by one or more hydraulic cylinders attached to a frame. The cylinders have a pulling stroke and a retraction stroke. A powered reel is used to store the wire as it is removed from the ground. During a pulling stroke, the reel is hydraulically isolated such that cable is stripped from the reel with tension maintained in the cable. During a retraction stroke, a motor turns the reel to load excess cable onto the reel.
