Why QIN-PCR200 DTH ?
- Compare with hydraulic crawler rock drill:
For example, Pakistan into the rainy season (May - October) and dry season (November - April), rainy season hot and wet, the temperatures between 20-40 degrees, the dry season temperatures between 30-50 degree.
For the hydraulic oil is also a severe deterioration than China, so compare with pneumatic crawler drill, the heat dissipation, maintenance, spare parts supply,etc.,is a big problem.
- Pneumatic crawler rock drill’s climbing ability adapt to a more complex field operating environment, smooth transitions, can temporary short distance towing — particularly suitable for the rugged complex initial mine construction site.
- Less maintenance, less ancillary time, low failure rate pneumatic components, easy maintenance, anti-high temperature.
