KG930A Overground Down The Hole Drill Rig

KG930A is one type machine improved from KY130. It works in open air.

On KY130base , KG930A optimize and upgrade the hydraumatic system , the part of drill boom and

part walking so on . It has better function than KY130, for example : more motor , stronger

gradeability ,more reasonable drilling angle , faster rotation and propulsion speed and so on . Its

horse power life is longer and reliability is better .
