Epiroc has introduced the Pit Viper 291 blasthole drilling rig at MINExpo 2021, in Las Vegas, today.

The large diameter, single-pass drill delivers productivity, application flexibility and enhanced operator safety with autonomous drilling options, according to the company.

Epiroc’s Pit Viper 291 is designed to tackle larger diameter drilling in soft- to medium-ground conditions. Capable of 279-311 mm diameter holes with 38 t bit load capacity, the new rig brings, Epiroc says, unsurpassed performance to any drilling operation and further extends the Epiroc Pit Viper range.

With Epiroc’s Rig Control System (RCS), the Pit Viper 291 can be configured with scalable automation features. Options like AutoDrill and AutoLevel or the optional BenchREMOTE package allow 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 Pit Viper 291 takes the Pit Viper series to another level with maximised force and torque for greater drilling efficiency and decreased downtime, the company says. The drill rig offers 356 kN of pulldown capacity, 156 kN of pulldown force and 11,000 ft-lb of torque.

Adrian Speer, Product Line Manager, Blasthole drilling, says: “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.”

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.

Along with the larger diameter capacity, the Pit Viper 291 offers more than 100 different options to configure the perfect drill rig for the specific application.
