Pit Viper 271: Rotary blasthole drill rig - Large-range

Rotary or DTH drilling up to 10 5/8” (270 mm) – Single pass
With a 75,000 lb (34 tonnes) bit load capacity, the PV-271 can add unsurpassed productivity to your mining operations. The heavy duty and durable PV-271 can drill a 55 ft (16.8 m) clean hole in a single pass. Single pass drilling yields higher drilling efficiencies (up to 25% when drilling in soft material) by eliminating rod change time and allowing more time for drilling. In addition to increased efficiency, eliminating rod changes also reduces the risk for operational errors.

Features & benefits

  • Patented high strength cable feed system with automatic cable tensioning and hydraulic double acting feed cylinders
