Excavator Mounted Rock Drills/Rock drill on the Excavator/
1.Definition
Without affecting the function of the excavator, the excavator can be transformed into a hydraulic rock drill or a down-the-hole drill by using the excavator’s built-in breaker oil circuit, connecting a special hydraulic conversion device, and removing the bucket. Then realize the multi-purpose function of excavator.This technology has obtained a number of national patents.
2. Advantage
（1 ）Low purchase cost;
（2 ）Low maintenance cost and simple operation;
（3） The use efficiency is comparable to that of the same type of drilling rig;
（4） Diversified functions of the excavator;
3. How to choose Hydraulic rock drill and DTH rock drill:
| Hydraulic Rock Drill

DTH rock drill
(big hole and long depth) |
|
| Hole Diameter(mm) | <115 | <350 |
| Hole Depth(m) | <10 | <40 |
| Power source | hydraulic pump of excavator | additionally equipped with a mobile air compressor |
| Air compressor | Smaller to rrain the slag | big |
| Mobile carrier | excavator | excavator |
