The Pit Viper 291 single-pass rotary drill is designed to tackle larger diameter drilling in soft to medium ground conditions. With 11-in. to 12 1/4-in. (279 mm to 311 mm) diameter holes and 85,000-lb (38 metric tons) bit load capacity, Epiroc said the Pit Viper 291 will provide unsurpassed performance to any drilling operation.

With Epiroc’s Rig Control System (RCS), the Pit Viper 291 can be configured with scalable automation features, including fully autonomous drilling. The RCS provides on-board automation capability with options like AutoDrill and AutoLevel or the optional BenchREMOTE package allowing an off-drill operator to run one or multiple units. The Pit Viper 291 is also capable of fully autonomous drilling with almost no human interaction with the drill for improved mine safety and productivity.

The 291 extends the Pit Viper series to another level with maximized force and torque for greater drilling efficiency and decreased downtime. The drill rig offers 80,000 lb (356 kN) of pulldown capacity, 35,000 lbf (156 kN) of pulldown force and 11,000 ft-lb of torque.

“The Pit Viper 291 is the perfect combination of large diameter drilling on a small platform. With proven performance throughout different regions and conditions, plus advanced autonomous features, the Pit Viper 291 will further exceed any drilling production requirements,” said Adrian Speer, Epiroc’s product line manager for Blasthole Drilling.

For ease of maintenance, the deck layout on the Pit Viper series offers convenient access to all major service components. Ground level, fast fuel-fill connections are standard, and optional ground-level live sampling is available. Spool valves are also centrally located above the deck for accessibility.
