KG920B Overground Down The Hole Drill Rig
KG920B is one type machine improved from KY125 . It works in open air.
On KY125 base , KG920B optimize and upgrade the hydraumatic system , the part of drill boom and part walking so on . It has better function than KY125 , 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 .
