6.6 m Extended Feed Stroke: accommodates 6 m drill rods and can reduce rod connection frequency compared with shorter-stroke setups.
300 m Drilling & 18 t Lifting Force: support deep water well projects and drill-string handling across a 140–325 mm bore range.
5,700–7,500 N·m Rotary Torque: provides hydraulic rotary capability for demanding ground conditions, supported by a crawler-mounted design.
Actual drilling depth and performance depend on geology, bore diameter, tooling and compressed-air supply. Confirm compressor requirements, rod compatibility and included accessories before ordering.
