Abstract
An apparatus consisting of sheaves/rollers is for guiding cables from a single pulling location through conduit that extends continuously between manholes and end points of conduit runs. The cable is set up at one end of the conduit run and a power driven tugger is set up at the other end of the cable pull. The apparatus is installed at each end of the run to guide the cables into the conduit through the manhole or out conduit stub. A rope is installed through the sheaves/rollers and into the conduit and then through another sheave at the other end and then connected to the cable. A power driven tugger is energized which causes tension on the rope and cable and pulls the cable through the end of the sheave.
