Rock Drills Designed for Tough Conditions

Atlas Copco has launched three new heavy- duty versions of its proven COP 1800 series hydraulic rock drills. The new models include the COP 1638HD, COP 1838HD and COP 2238HD and are intended for face drilling in underground mining and tunneling projects involving tough condi- tions. A primary feature of the new drills is a new side-bolt design consisting of four front bolts and two at the rear. This mini- mizes the risk of impact piston misalign- ment and secondary damage to internal parts. It also improves serviceability due to easier side-bolt torque procedures. In addi- tion, says the company, the front head has been strengthened, making the rock drills more robust for demanding conditions.
