CMJ1-14 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 simple to operate, incorporates the auto stop and anti-jamming function, auto-stop at end-point, auto wash. 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 cannot only drill blast hole, according to the basis of section, it can drill bolt hole conveniently with our patent impeller.
