HT72 Hydraulic Jumbo Drilling Rig

HT72 Hydraulic Jumbo Drilling Rig is mainly uesd for production long hole drilling in metal or nonferrous metal mines underground, which can work in cross section 3.5m x 3.5m--4.5m x 4.5m tunnels. It is an ideal equipment for production processing on pillarless sublevel caving method and can meet special requirement on multi-positioning and production drilling in underground mines. With their reliable position system by sliding bench and rotary feeder, and has features of precision hole drilling, powerful drifer, advanced electrical hydraulic control technology, the jumbo is capable of ring-drilling parallel holes at high efficiency in suitable section after it once jacked.
