KG series semi-hydraulic open-air crawler rig
KG920B semi-hydraulic medium wind pressure open-air crawler drilling rig

KG920B type open-air drill rig on the basis of KY125 drilling rig, optimize and upgrade the hydraulic system, drill arm parts, walking components, Increase power (YC4D80) climbing ability is stronger, more reasonable drilling angle,faster rotation speed and advancing speed,longer motor service life,better reliability.
