FC20-2BCD hydraulic Drilling jumbo is mainly used to drill blast holes for tunneling constructions in mining, metallurgy, water and electricity, railway, highway engineering, etc. This series use all hydraulic drive, two booms work together, 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. Working with electric motor can improve the working environment a lot, reduces noise, dust and energy consumption. The flexible hydraulic rock drill can work on the section, roof, side and floor. The jumbo can not only drill blast hole,according to the the basis of section, it also can drill bolt hole conveniently with our patent impeller.The jumbo runs with both wheels and crawler, even suit working in bad environment.
