A low profile small diameter raise drill, ideal for slot raises, back filling and narrow vein mining applications. It can be used for conventional raiseboring, downreaming as well as upward boxhole boring. This makes the Robbins 34RH C Wide the most versatile raise drill on the market. The wide frame enables a 1 060 mm reamer to pass the work table.


Features & benefits

  • Remote controlled hydraulic worktable enables the reamer and stabilizers to pass through the mainframe.
  • The single hydraulic drive power pack features variable speed and excellent torque limiting control
  • Telescopic thrust cylinders provide high thrust in low profile
