350 m Drilling & 22 t Lifting Force: support deeper water well projects and heavy drill-string handling across a 140–325 mm bore range.
6.6 m Extended Feed Stroke: accommodates 6 m drill rods and can reduce rod connections compared with shorter-stroke configurations.
6,200–8,500 N·m Rotary Torque: provides hydraulic rotary capability, with air and mud drilling options for different ground conditions.
Actual drilling depth and performance depend on geology, bore diameter, tooling and the selected drilling system. Confirm the compressor, mud pump and accessories included before ordering.
