    Abstract: A horizontal pipe ramming system includes a hydraulic crowd system. A hydraulic percussive hammer is mounted on a carriage that is urged forward by hydraulic cylinders acting between the carriage and an abutment. The continuity of crowd is enhanced by a compressive resilient assembly that releases its energy to the hammer to keep it in contact with the pipe after impact.
