1. The drill head rotation is realized with four hydraulic pumps
driven by five diesel engines; this also makes the feeding
hydraulic cylinder system realize its full stroke feeding in both
higher and lower speed.
2. The rig is adopted fission style in design, including power
unit, hydraulic oil tank, manipulation platform and operation
mechanism, i.e. the drilling section. So they are in light weight
and can be carried by man power or animal power. The rig can be
applied and performed in narrow space for drilling of hole at
45°-90° with stronger adaptability.
3. Besides diamond drilling with wire line coring tech, DF-H-2 core
drilling rig is applicable for drilling and feeding requirement of
any other stratum.
4. It is suitable to use in plains, hills, high temperature as well
as low temperature places.5. It is wire-line coring, and at the same time has the unique top
drive function, which will be much more suitable for large diameter
drilling in coal bed methane, hydrology and water well.
6. Excellent in performance,high in working efficiency, easy for
operation and keep the operators from dangers.
