Hqd70 Small Electric DTH Drilling Rig/ Down The Hole Drilling Rig
Application and Feature:
1. It is a new rock drilling equipment with energy saving, high efficiency designed by ourselves.
2. It is widely applied to larg, medium and small mining, road, national defence, water conservancy, big stone project and side slope working, etc for blasthole drilling. It's also a necessary rock drilling equipment for earlier explore of open air mine.
3. It is specially useful for rugged and accidented areas where other DTH drilling rig can not work normally.
4.This drilling rig features compact structure, easy operating, fast drilling, high efficiency, easy to disassemble and very convenience for carrying.
