a1.hole diameter:105-152mm.
2.depth:25m
3.high air pressure
KG940A is one type machine improved from KY140. It works in open air.
On KY140base , KG940A optimize and upgrade the hydraumatic system , the part of drill boom and part walking so on . It has better function than KY140, 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 .
