1 - Brief introductions of KQZ-70D pneumatic-electric DTH drilling rig

KQZ-70D pneumatic-electric DTH drilling rig is a new type of high efficient drilling rock equipment designed for water conservancy projects and construction sites.

It is widely used for drilling in all kinds of rock strata in open pit, water conservancy and construction slope treatment.

KQZ-70D pneumatic-electric DTH drilling rig is a percussive rotary drilling rig.
