    摘要: An apparatus for pulling a cable through a conduit includes a frame that has a base. The apparatus further includes a boom that has at least one roller configured to guide a rope connected to the cable along the boom. The boom also includes a main boom pivotally connected to the base and an upper boom pivotally connected to the main boom. A drive unit connects to the boom and includes a rotatable spool configured to pull the rope along the boom. The apparatus further includes a lift pivotally connected to the frame and the boom. The lift is operable to move the boom relative to the frame.
