Rugged and well-proven design which offers high availability and great flexibility

The SmartROC D55 is fitted with a robust feed which includes sensors inbuilt into the rod-handling systems and carousel motor. These sensors reduce breakdowns and lead to more reliable rod-handling.

Massive fuel-savings

The Rig Control System (RCS) makes substantial fuel-savings a reality. The RCS automatically controls the compressor load and engine RPM, ramping-up or reducing as is necessary.

High productivity that you can count on

The SmartROC D55 is highly automated. It takes care of drilling holes on its own. The rig adds rods automatically and extracts them when the desired depth is reached. This reduces operator fatigue, minimizes the risk of accidents and offers unrivalled consistency.
