Cop 1838

Face drilling/long-hole drilling

Atlas Copco Hydraulic rock drills

COP 1838ME/HE
Technical specification

A series of high-speed, hydraulic rock drills for face drilling and long-holedrilling in the hole range 38–89 (102) mm. High penetration rates and excellent drill steel life.

Features and benefits
• Efficient, hydraulic dual-damping system absorbs and dissipates the shockwavesfrom 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 riskingnontightening 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 rotationmotor gives high torque for efficient drilling, and minimizes the risk for jamming. • Separate lubrication of fronthead and driver together with pressurized and lubricated mating surfaces and sideboltsfor the best protection against wear and corrosion. • The low profile of COP 1838ME/HE permits drilling close to walls with only 2 degrees lookout angle. • Two nitrogen-charged accumulators plus oneaccumulator for the return oil, levels out pressure peaks in the hydraulic systems. This reduces vibrations and wear on hydraulic components.
