Sandvik: Rotary Blasthole Drill Rigs
Sandvik rotary blasthole rigs are designed to drill big blast holes into high benches in large quarries and opencast mines. Designed for very high production rates, they employ either rotary or rotary and DTH drilling, depending on the model. With long, high-strength masts and extremely robust components, they can develop very high rotational torques and pulldown forces. This, together with abundant flushing air and responsive ergonomic controls, gives very high penetration rates in continuous duty.
