Atlas Copco unveils its newest drill rigs in the SmartROC series, the D50 and D55. The rigs are powered by low-emission engines, which adapt their output to the task at hand at all stages of production. The Rig Control System (RCS) allows for intelligent control of engine RPM and air compressor load for more effective penetration with lower fuel consumption and decreased wear on components. Automatic rod handling and uniform feeding also enhance productivity. The D50 is designed to drill holes with a diameter of 3 1/2 to 5 1/8 inches, while the D55 drills a slightly larger diameter of 3 1/2 to 6 inches at depths of up to 148 feet.
