Rotory drill with tricone bit for open pit mine

◆ High axial pressure, high torque, high rotating speed and large aperture provide excellent productivity for mining operation.
◆ Electric/ diesel dual-power system, optional high/ low pressure or low-pressure air compressor, which is energy-saving and low pollution.
◆ Electro-hydraulic ratio control system with variable constant power is adopted to match operation parameters according to strata movement.
◆ Equipped with high reliable three-point floating leveling chassis and high-strength truss drill tower.
◆ Combined gearwheel rotation and DTH impact modes for wide adaptability of strata.
