ABSTRACT:
An underground directional boring machine includes a frame and a drive mechanism slidably mounted on the frame. A drill string is coupled to the drive mechanism for rotation and longitudinal advancement and retraction. A drive assembly moves the drive mechanism along the frame. The drive assembly includes two hydraulic cylinders coupled to the drive mechanism and extending in opposite directions. Free ends of the hydraulic cylinders are releasably secured to the frame at any one of a plurality of positions along the length of the frame. Selective pressurization of the cylinders results in sequential movement of the drive mechanism along the frame by alternative extension and retraction of the cylinders.
