Drilling jumbo for tunneling constructions in mining
drilling jumbo is mainly used to drill blast holes for tunneling constructions in mining, metallurgy, water and electricity, railway, highway engineering, etc. This series uses all hydraulic drive, with high efficiency and speed which can be 0.8-2 m/min.
The advanced hydraulically controlled drilling system, which is safe and easy to operate, incorporates the auto-stop and anti-jamming function, auto-stop at end-point, auto- wash.
This jumbo has a small body, runs with the crawler, can climbing flexibly on 14°slope. It can runs by electric and diesel engine, to ensure running and working when power shortage. The flexible hydraulic rock drill can work on the section, roof, side and floor. The drilling rig can not only drill blast hole, according to the basis of the section, it also can drill bolt hole conveniently with our patent impeller.
