CME CME-50DD

Central Mine Equipment designed the CME-50DD horizontal directional drilling unit with dual range thrust and rotation. This high-torque/low speed or low-torque/high-speed system is changed from one mode to another with the turn of a selector valve, even without the need to stop rotation. Carriage travel speed and force can also be changed from low to high range as drilling conditions dictate. A pivoting operator's station allows for improved view of all drilling operations. Safety and convenience is enhanced via remote-control tramming of the machine, which utilizes a rack-and-pinion drill-rod feed and retract system.
