Range of Application

Drilling jumbo is mainly used to drill blast holes for tunneling constructions in mining, metallurgy, water and electricity, railway, highway engineering, etc. Siton drilling jumbo can be used in small tunnel sections 2x2m Min.as well as big tunnel section 7.5x8m Max.

Main Characteristics

1.Drilling jumbo is safe and simple to operate, incorporates the auto stop and anti-jamming function, auto-stop at end-point and auto wash

2.It can not only drill blast hole, on the basis of section, with our patent impeller, but can also drill bolt hole conveniently
