For the KG930-type open-air down-the-hole drill carriage, hydraulic system, drill boom parts and carriage parts are optimize and upgraded based on KY130-type open-air down-the-hole drill carriage, so as to make hole drilling angle more proper, rotary speed and advance rate faster, service life of motor longer and the reliability better.

KG series is revised on the basis of KY series, which maintains the simple structure and stable performance of KY series and upgrades the hydraulic system, travelling unit, gyrator, power, gas path system, drill arm component and rack unit, enjoying increased power, stronger climbing ability, more reasonable drilling angle, faster rotation and advancement speed, longer-term motor service life and better reliability. This drill is widely used in blasthole drilling of large- and medium-sized open-air mining, water conservancy, power station and road paving projects. Applicable rock hardness: F=6-20, drilling diameter: 80-165mm, economic drilling depth: 12-25m.
