The SmartROC D50 and D55 are versatile rigs powered by low-emission engines, which can adapt their output to the task at hand at all stages of production. The Rig Control System (RCS) in these rigs allows for intelligent control of engine rpm and air compressor load for more effective penetration with lower fuel consumption and lesser wear on components for greater longevity, the manufacturer explained. Automatic rod handling and uniform feeding also offer greater productivity and efficiency on site.
The SmartROC D50 is designed for precision drilling of holes with a diameter of 90-130mm (3½-5 1/8in), while the SmartROC D55 is specialised for holes with a slightly larger diameter of 90-152mm (3½-6in) for depths down to 45m (148ft), while more shallow holes can be drilled with a larger diameter. Atlas Copco stated that its Hole Navigation System is an intelligent option for SmartROC rigs for fast and accurate collaring and drilling to the desired depth and inclination.
