Technical specification

COP 1638Hydraulic Rock Drills

The COP 1638 is developed from COP 1838ME with its well-known COP 1800 technique. In order to give best performance at 16 kW impact power the interior parts are new designed. COP 1638 drills significantly faster and provides a significantly better drill steel life compared to COP 1238ME or similar rock drills.The COP 1638 is the optimal choise for upgrading old drill rigs with COP 1238ME/DCS 12, COP 1432/DCS 14 or similar competitor rock drills, to provide higher productivity and better drilling economy.

Impact piston design matches the size of the drill steel. This feature gives minimum drill steel stress.

Very easy to adapt the rock drill to different rock or bit condi-tions.

The well-known Atlas Copco double-dampening system pro-vides good bit-rock contact giving high penetration rates, and is gentle to the drill steel, absorbs harmful recoil energy and tightens drill steel thread joints.

Powerful, stepless variable and reversible rotation motor gives

high torque and enables great rotation speed flexibility. Separate lubrication of fronthead and driver together with

pressurized and lubricated mating surfaces and sidebolts for the best protection against wear and corrosion.

In especially corrosive environment, a front head entirely made of corrosion resistent material (AW-version) is available for extra long service life. (See also printed matter 9851 2334 01)

External sealed off water flushing for pressures up to 25 bar ensures efficient removal of cuttings and better bit life.

Low profile permits drilling close to walls with only 2 degrees look-out angle.

Features

A 16 kW hydraulic rock drill for fast tunnelling and drifting in the hole range 33 - 76 mm. High penetration rate and excellent drill steel life.
