KG940A-D06 borehole DTH hammer Drilling Rig1.drill at open air mine2.new upgraded functions3.good quality for tested
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 .
