The present invention is a pipe-joining machine for installing successive pipe units. The pipe-joining machine includes a longitudinally extending base assembly having a front plate, a rear plate spaced from the front plate and connecting bars joining the front and rear plates. A hydraulic cylinder, having a drive rod, is mounted and extends horizontally rearwardly from the rear plate. Control mechanism including a multipassage hydraulic valve is in communication with the hydraulic cylinder. A gripper mechanism is provided on the free end of the drive rod and is effective for releasably grasping a cable. One end of the cable is fed through successive ones of the pipe sections being installed and rearward movement of the hydraulic cylinder drive rod applies a pulling force to the last pipe section in the chain to properly seat the last pipe section with respect to the adjoining pipe section.
