The DR-2SB hydraulic jumbo drill, a dual-boom hydraulic rig, is designed for drilling vertical, horizontal and angled holes in underground production or development headings. The DR-2SB has boom coverage of 7.10 m by 8.90 m (23.3 ft by 29.2 ft) and inner and outer turning radius’ of 3658 mm (12.0 ft) and 6839 mm (21.0 ft), respectively.
The DR-2SB features the Intelsense drilling control system, which includes the following features:
- Collaring
- Anti-jamming
- Automatic water monitoring with feed return if low pressure is encountered
- Auto return to start position after hole completion
- Control levers for operating percussion, rotation, and feed
The DR-2SB also includes robust drilling and carrier hydraulics that feature variable displacement piston pumps; specifically:
- Jumbo hydraulics: load-sensing, closed-circuit design for percussion, rotation, feed, and boom movements
- General hydraulics: load-sensing, closed centre circuit design for optimal efficiency
- Steering hydraulics: load-sensing, closed centre circuit design; stick steering with direct-acting control valve and two double-acting steer cylinders
Our ROPS/FOPS-certified, environmentally controlled operator’s cab uses advanced air filtration and a climate control system to insulate your operator from particulate matter and other harmful emissions. Noise is reduced significantly through the use of integrated insulation throughout the cab structure; in addition, vibration dampeners isolate the cab from the frame, ensuring a safe and comfortable ride.

Montabert drifters
Our industry-leading Montabert drifters mean you receive the best possible drifter for your drill rig. Montabert HC series drifters have consistently, over the years, provided the lowest-per-drilled meter costs as compared to other drifters on the market.
Montabert drifters are known for:
- Longest maintenance intervals, resulting in highest availability
- Lowest maintenance costs
- Reliability
- Faster drilling speeds
- Lowest tool consumption
- Easiest to operate
- Highest penetration rates
- Lowest noise level
Montabert drifters provide maximum shock wave transmission; piston shape improvements mean that most of the shock energy goes directly to the bit, without tool fatigue. In addition, Montabert drifters excel in energy recycling; rebound energy is re-injected in the supply circuit, allowing the rebound energy to be used for the next cycle.
The HC-50 drifter is ideal for small headings and bolting application and is designed to reduce the lead length of the feed.
