1. Strong drilling ability: 60meters, 115~140mm hole diameter.

2. Hydraulic control system, powerful for drilling and easy to operate.

3. Crawler type, convenient for moving and suitable for any place, especially muddy and rugged place.

4. Working with air compressor, high efficiency and low air consumption, drills about 2 meters per 5 minutes.

5. Widely used in open mining, road building, rock drilling, blasting holes.
