Application of drilling rig
1. Applied for general investigation, geophysical exploration, highway, building construction and blast-hole drilling etc.
2. with hydro-automatic feeding device, and high drilling efficiency.
3. Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
4. Close levers, convenient to operate, safe and reliable operations.
5. Crawler type, suitable for rugged venue operations, very easy to move and transport;
6. Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas.
