Product Description

CMJ2-18 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 simple 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 large slop. 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 also can drill bolt hole conveniently with our patent impeller.
