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 5.49 m by 7.04 m (18' 0" by 23' 1") and inner and outer turning radius’ of 3.76 m (12’4”) and 6.68 m (21’11”), 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 center circuit design for optimal efficiency
  • Steering hydraulics: load-sensing, closed center 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.
