Advantages
Key Features
- 650 m NQ / 450 m HQ in a split package that fits a 2 m drift.
- Rig, power station and console are separate: hydraulic hoses only, no rigid frame to manhandle underground.
- 0 – 180° head angle with 1,800 mm stroke and 100 kN feed — collars roof, wall and floor holes.
- 55 kW 380 V electric motor; no ventilation load from a diesel engine underground.
- Constant-torque hydraulic head suits impregnated bits in hard, abrasive mine rock.
- Used for resource definition, old-working re-sampling and geological hazard drilling from the drift.
