1. A cable pulling system, comprising:
a cable pulling device, including:
an extending and contracting beam including a first end portion and a second end portion;
a pulley attached at a distal end of the first end portion, such that when in operation, the pulley moves back and forth as the beam extends and contracts; and
a cyclic cable gripper attached to the extending and contracting beam, wherein the cyclic cable gripper is configured to pull a cable through a length of pipe by gripping the cable on a beam extension, and automatically releasing the cable on a beam contraction.
