Crawler-type layout, the feeding and lifting of rotator are drive by series motor with gear and chain with a long stroke, 3.5m stroke. The rotation of spindle is driven by a singel engine. It has four mechanical shifts, and it speed could be adjusted by hydraulic pressure with stepless speed change. The mast has the function of sliding and touching ground; the spindle lifted and lowered with oil cylinder; it could be folded for transportation and storing. The spindle has a big diameter hole. The spindle has high-precision structure.  

    This type of drill rig can take the place of imported products and be applied in the fields of geology, metallurgy, coal mines, petroleum, natural gas and underground water exploration.

    Rotary Reamer is designed for various reams in drilling operation. HCR-8 is suitable to use in plains, hills, high temperature as well as low temperature places. The main machine is integrated in structure, which consists of self-propelled chassis, power, mud pump and hoist, etc. It is wire-line coring, and at the same time has the unique top drive function. The Maximum torque is 7200N.m (5307lbf.ft), wihch will be much more suitable for large dia.drilling in coal bed methane, hydrology and water well.
