Abstract: An electric auger-boring machine. The machine has electric motors for auger rotation and thrust. The electric rotation motor rotates the auger at a constant rate when the current provided is constant. The motor may slow or stop in response to changes in torque due to obstructions to auger rotation. Electric motors allow for auger thrusters and actuators to precisely operate. A wireless remote control controls motor and auger rotation and thrust from a distance away from a launch pit. Multiple sizes of product casings may be utilized and the auger-boring machine comprises an adjustable adaptor and saddle for use with a plurality of casing sizes.

Abstract: A tool for making up and breaking out a drill string at an exit side of a bore. The tool includes a fixed wrench assembly and a moveable wrench assembly for torqueing a pipe joint. The tool also includes a drill pipe retainer assembly that is mounted indirectly of the frame and is adapted to receive and release a pipe section. A roller assembly is provided at a special hydraulically-adjustable table to allow low-torque unthreading and threading of pipe segments.
