Product Description
                 Portable fully hydraulic DF-H-2 wireline diamond core drilling rig machines
Product Application
DF-H-2 Fully Hydraulic Portable Drilling Rig is a kind of light rig designed for geological explorationin 
remote area difficult  to enter.  It is mainly suitable for diamond drilling with wire line coring technique. 

Main Features
1.  Full  Hydraulic and Drill Head model 
The drill  head rotation is realized with four hydraulic pumps driven by five diesel engines(has been advanced with Two larger diesel engines); this 
also makes the feeding hydraulic cylinder system relize its full stroke feeding in both higher and lower speed.
2. In good disassemblability 
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. Strong techniques adaptability 
Besides diamond drilling  with wire line coring  technique, it is in strong techniques  adaptability.  It is applicable for the drilling and feeding requirement of any other stratum.
