New rock drill to face tough conditions Jul 2010
Atlas Copco has launched three new heavy-duty versions of its well-proven COP 1800 series of hydraulic rock drills. The newcomers – COP 1638HD, COP 1838HD and COP 2238HD - are intended to make short work of drilling face and long-hole drill holes in faces of tough rock conditions in underground mining and tunnelling projects.

The new COP 1800HD series of heavy duty, hydraulic rock drills

The new heavy duty, high speed, hydraulic drills will tackle drill holes in the range of 38-64mm diameter.
One of the main new features is a new side bolt design consisting of four front bolts and two at the rear, to minimize the risk of impact piston miss-alignment and secondary damages to internal parts. Easier side bolt torque procedures also improve serviceability.
In addition, the front head has been considerably strengthened, making the rock drills more robust for demanding conditions. This means that more material absorbs the energy that is generated by the shock waves reflected from the rock, thereby protecting the drill.
"The scope when developing these new heavy duty versions of the rock drill was to extend the service intervals and minimize total downtime, even when drilling in very tough conditions," said Peter Bray, Product Manager, Face Drilling Equipment at Atlas Copco.
"We have been field testing at a number of locations with extremely demanding conditions, and the machines have been performing beyond expectations."
