Application
Characteristics
1. Diesel engine mounted hydraulic system, all the system include the walking, rotation, feed, lifting, Leg, lifting, compensation system, rod change is hydraulic.
2. Reverse circulation system working together with DTH technology, air compressor provided pressed air for impact and dust collect.
3. During working, use the reverse circulation hammer, double tube, pressed air enter between two tube and dust out from the inner tube.
4. Also it’s available to positive circulation use normal drilling tool.
5. The working system composed of feed system, guide(mast), rotary head, compensation system, centralizer, rod exchange system, winding and so on.
6. Axes pressure, feed speed, rotary speed is adjustable.
7. The walking system is a self-walking system, convenient for moving, which could install four hydraulic leg, when load on truck, it doesn’t need hiking up, it can load on truck directly.
8. Four hydraulic leg use for keep the balance of the drilling during working.
9. The sub winding could hoisting Max.1ton drilling tool, it also could help to rod change.
10. The guide(mast) could working in 45°-90°, guide have a extension system, which ensure the guide could moving toward the drilling surface, to keep the balance of the guide.
11. Gradienter, angle label and centralizer to ensure the precision accuracy of hole.
12. The air system have a special lubrication system to lubricating the hammer to extend the service life.
