Atlas Copco Hydraulic rock drills

COP 3038 Technical specification

A 30 kW hydraulic rock drill for fast tunnelling and drifting in the hole range 43–64 mm. Exceptionally high penetration rate and excellent drill steel life.

Features and benefits • Efficient, 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. • High-frequency technology - instead of striking the drill steel harder, the piston strikes it at higher frequency. This makes it possible to drill exceptionally fast without increasing the stress on the drill steel. • Low and slender profile permits drilling close to the walls. • Double sealed flushing chamber, which complies with up to 40 bar water pressure and less risk of waterintrution into rockdrill. • Easy to service with few, small and light weighted parts.
