The Epiroc Pit Viper 291 single-pass rotary drill is designed to tackle larger diameter drilling in soft to medium ground conditions. It is capable of 11 inch to 12 1/4 inch (279 mm to 311 mm) diameter holes with 85,000 pound (38 tonnes) bit load capacity. 

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, improving safety.

The Pit Viper 291 takes 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 pounds (356 kN) of pulldown capacity, 35,000 lbf (156 kN) of pulldown force and 11,000 ft.-lbs. of torque.  

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 specific applications.
