Df20 2bd Double Booms Track Hydraulic Rock Drilling Jumbo - China

DF20-2BD hydraulic rock jumbo 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 easy 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 14°slope.

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 can not only

drill blast hole, according to the the basis of section, it also can

drill bolt hole conveniently with our patent impeller.

The jumbo runs

with both wheels and crawler, even suit working in bad environment.
