ABSTRACT:
An apparatus and method for installing pull lines in conduits and retrieving the installed pull lines with an attached electrical cable through the conduit is disclosed. The apparatus provides a single structure which both installs the pull line and retrieves the installed line with a, for example, electrical cable or a heavier pull line attached. The device features an elongated valve actuating handle provided with a line containing reel. A driving pneumatic force can be attached to the handle operable through the valve portion thereof. The handle is provided with a chamber at its end portion which dispenses both the pull line from the reel, and driving pneumatic pressurized fluid. The device is provided with a vehicle which sealably contacts the walls of any conventional conduit and travels therethrough with the end portion of the pull line from the reel attached thereto. When the vehicle and attached pull line exit at an opposite end portion of the conduit through which an electrical cable is to be installed, the pull line can be hooked to the end portion of the electrical cable (or to a heavier pull line) and then reeled back through the conduit thus installing the desired cable or heavy pull line in the conduit. The line installed on the reel is the only line needed for initially traveling through the conduit with the vehicle and thereafter pulling the electrical cable or a heavier pull line through the conduit for the final installation.
