Sandvik Mining and Construction has released the DR460 rotary drill rig, a diesel-powered drill designed for 251mm to 311 mm diameter blastholes and high penetration rates.

According to the manufacturer, the DR460 has nearly 40% more rotary hp than its nearest competitor.

“When ground conditions allow, the operator can increase bit rotation speed without sacrificing torque, which allows for substantially higher penetration rates,” Sandvik Mining and Construction Regional Product Line Manager for Rotary Drills, Neil Emery said.

The rig is capable of drilling to depths of 75 m using 194 mm diameter by 12.8 m long drill pipes, or to 62 m deep using 219 mm diameter pipes.

Full perimeter walkway and maintenance platforms allow the operator and technicians full access around the drill.

According to the company, the drill’s hydraulic valves have been positioned closer to their points of use to limit the amount of hoses in a single location and increase safety levels.

“By focusing on routing, securing and shielding of hydraulic hoses and electric wiring, there is a dramatic improvement in the reliability and maintainability of these systems,” Emery said.

The operator cabin consists of a 4.4 m2 FOPS-rated cabin with chair-mounted joystick controls and floor-to-ceiling windows provide a clear view of the drill deck.
