Epiroc Pit Viper 351 autonomous at gold mine

Product description

The Pit Viper name has become synonymous with productivity in the mining indsutry, and the Pit Viper 351 drill rig is the Pit Viper that started it all.


When it comes to drilling large holes in hard rock, you can't compromise anywhere. The PV-351's powerful rotary head, high bit load, large compressor, and robust structure bring balanced power for the hardest rock. With a 56.7 ton (125,000 lbs) bit load capacity, the Pit Viper 351 can add unsurpassed productivity to your mining operations. 


If technology, productivity, and long asset life with the lowest total cost of ownership are on your list of priorites, look no further than the Pit Viper series. Equipped with a standard Rig Control System (RCS) operating platform, today's PV-351 sets the bar for productivity and reliability when large blastholes are part of the production plan.
