COP 1028-T/2 8311 1200 53 Mounted on the feed cradle at the end of the boom, this hydraulic rock drill is the heart of your rig's operation. It combines a hydraulic motor for rotation with a percussion mechanism that generates the hammering action. Both systems work together to drive the drill string into the rock face, creating the blast hole.

The condition of the drifter directly impacts overall productivity and reliability. Consistent impact energy and torque are essential for achieving planned penetration rates. If internal seals begin to fail, for instance, hydraulic fluid can bypass the piston, leading to a noticeable loss of impact power and slower drilling. This not only slows down the cycle but also increases stress on the drill steel.

Listen for changes in sound during operation and watch for external oil leaks, especially around the front head and hose connections. A sudden drop in drilling speed or erratic rotation are clear signs that internal service is needed. Adhering to the recommended service intervals for seal kits and major overhauls is the best way to prevent unexpected downtime.
