Sandvik’s new DE100 range of exploration drill rigs is being expanded to include the DE150. A surface version is under development and will be ready for market fourth quarter 2009. The DE100-series drills are made to handle all types of drilling conditions within the scope of modern core drilling. The series includes drills with capacities for deep hole drilling, as well as short-hole drilling, for production control. Drills for special applications can be customized, based on customer’s needs. Additional equipment like water pumps, wireline equipment, and a range of power pack alternatives are available for different applications. The DE150 is powered by a hydraulic motor capable of producing torque of 2000Nm at 485rpm. A hydraulic feed cylinder design gives a push and pull capacity of 15t and depth capacity of up to 2000m. In underground applications the DE150 is powered by an 110kW electric power unit giving a maximum working pressure of 250bar and oil flow of 300ltrs/min. For surface application the DE150 can be powered by a diesel engine. The DE150 shares many of the components used by other drill rigs in Sandvik’s DE100-series. The drill unit features a stiff and torsion resistant steel profile feed boom and a direct coupled feed cylinder with a feed length of 1700mm and feed speed of max 0.63m/s.
