Face drilling/long-hole drilling
Atlas Copco Hydraulic rock drills
COP 1838ME/HE Technical specifcation
A series of high-speed, hydraulic rock drills for face drilling and long-hole drilling in the hole range 38–89 (102) mm. High penetration rates and excellent drill steel life.
Features and benefts • Efcient, hydraulic dual-damping system absorbs and dissipates the shockwaves from the rock, as well as establishing the best possible contact between the drill bit and the rock. This feature makes it possible to transmit maximum power to crush the rock without risking nontightening of threads in the drill string. • Impact piston design matches the size of the drill steel. This feature gives minimum drill steel stress. • Powerful, stepless variable and reversible rotation motor gives high torque for efcient drilling, and minimizes the risk for jamming. • Separate lubrication of fronthead and driver together with pressurized and lubricated mating surfaces and sidebolts for the best protection against wear and corrosion. • The low prole of COP 1838ME/HE permits drilling close to walls with only 2 degrees lookout angle. • Two nitrogen-charged accumulators plus one accumulator for the return oil, levels out pressure peaks in the hydraulic systems. This reduces vibrations and wear on hydraulic components.
