Cmj2 18 Coal Mine Track Double Booms Hydraulic Drilling Rig - China
price: contact company for price
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.
