DR2S1 Drilling jumbo

Features:
1.DR2S1 drilling jumbo (face drilling rig) is mainly used to drill blast holes for tunneling constructions in mining, metallurgy, water and electricity, railway, highway engineering, etc. 

2.It uses all hydraulic drive, two booms work together, with high efficiency and speed which can be 0.8-2 m/min. 
3.The advanced hydraulically controlled drilling system incorporates the auto stop and anti-jamming function, auto-stop at end-point, auto-wash. 
4.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.
5.The flexible hydraulic rock drifter not only can work on the section, roof, side and floor. but drill blast hole, according to the the basis of section and drill bolt hole conveniently with our patent impeller.
