The DF30-1BCDL drilling jumbo is mainly used to drill hole for tunnel construction in mining, metallurgy, water and electricity, railways, highway engineering, etc. This series uses all hydraulic drive, with high efficiency and speed that can be 0.8-2.5m / min. The advanced hydraulically controlled drilling system, which is safe and easy to operate, incorporates the function of automatic stop and anti-jam, automatic stop at the end point, automatic washing. This jumbo has a small body, runs on wheels, can reach a speed of 8 km / h. Working with electric motor can greatly improve the working environment, reduce 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 a blast hole, according to the base of the section, it can also drill a bolt hole conveniently with our patented impeller.
