A cable pulling machine of the invention includes a frame, a mechanical linkage including first and second links having first and second cable gripping shoe s disposed thereon respectively in opposed positions, a latching cylinder actuable to cause the mechanical linkage to pivot on multiple axes to bring the shoes into engagement with a cable disposed therebetween, a main cylinder having one end mounted on the frame and actuable to move the linkage in a manner effective to pull the cable in a pulling stroke once the latching cylinder has brought the shoes into engagement with the cable, and suitable means for extending and retracting the main and latching cylinders. The machine may also include suitable means for holding the cable in tension between pulling strokes, such as a pivoting wedge mechanism as described hereafter. |
