COP 2238HD+T 8311 1275 02 The rock drill is the core of your rig's performance, converting hydraulic flow and pressure into powerful impact energy and rotation. It is mounted on the feed cradle and is responsible for driving the drill string into the rock face. The efficiency of this unit directly determines the penetration rate and overall productivity of the entire drilling cycle.

Proper function of the internal piston, rotation motor, and valve systems is critical for reliable operation. A drop in accumulator pressure, for example, will immediately reduce the impact energy and slow down drilling. Consistent performance from the drifter ensures straight holes and reduces premature wear on drill steel and bits, ultimately lowering your cost per meter.

Watch for symptoms like low drilling speed, oil leaking from the front head, or a change in the sound of the percussion. These often indicate internal wear or a loss of accumulator charge. Regular checks of lubrication flow and side bolt torque are essential for maximizing service life before a full rebuild is required.
