Main feature：
1. Being highly automatic in construction with rock drilling speed much higher than that of manual pneumatic drill.
2. Requiring only 2 operators, which greatly reduces the staffing and improves the economic benefits.
3. Designed with electric proportional control system to remove the complex hydraulic oil pipes, which is convenient for daily maintenance.
4. Equipped with computer guidance system to facilitate drilling and positioning of drill arm.
5. Featuring flexible adjustment of boom posture to accurately control the drilling angle and depth to avoid secondary drilling and blasting.
6. Designed with self-adaptive pressure value during drilling, so as to reduce the consumption of drilling tools and the cost of parts.
7. Coming with lifting closed cab with a wide field of vision and high safety factor.
8. Equipped with water mist slag flushing system and hole blower to effectively remove the stone slag in the hole and improve the drilling efficiency.
9. Mounted on the four-wheel drive chassis to realize flexible rotation and high mobility.
