Epiroc's range of mine trucks for underground mining and tunneling applications includes models with payload capacities from 20-65 tonnes. The articulated underground trucks have a high power-to-weight ratio for good speed on steep grades. The computerized drive system, Rig Control System, RCS, provides service information and diagnostics that are logged as well as displayed on the screen inside the cab. It is a powerhouse designed for fast, productive haulage in substantial mining and construction operations where navigation through narrower tunnels is required. The build in reliability combined with higher capacity and high ramp speed leads to dramatically increased productivity. Operators work in comfort with optional air conditioning and ergonomic controls, boosting productivity and reducing fatigue.
