DF-H-2 Full Hydraulic Drill Head Core Rig is a kind of light rig designed for geological exploration in remote area difficult to enter.It is mainly suitable for diamond drilling with wire line coring 
technique.

 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.

 Established in 1970s, Zhengzhou Defy has growned into one leading drilling rig manufacturer in China, specilizing in drilling rig technology R&D, manufacturing, etc. We spark on conventional rotary drilling rig, new pneumatic drilling rig and are inventing another drilling rig with performance same as pneumatic one, but with much less investment for users.
 
Our drilling rigs are widely used for water well drilling, irrigation well drilling, geothermal hole drilling, mining blast hole drilling, construction pile work drilling, air-conditioner hole drilling, etc.
 
DEFY Brand drilling rigs have been widely exported to Chile, Russia, Australia, Malaysia, Kenya, Tansanzia, Zambia, South America, Peru, Zimbabwe, etc.
 
Every customer is very welcomed to our factory for visiting driling rig,  talking onsite and details. ^_^

 How to choose a suitable drilling rig? 

1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?
2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more. 
3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.
4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one. 
C. Mainly hard rock, like granite.
Based on the above information, DEFY experienced engineers will help you recommend suitable machine and price. If you have special demands, please tell us ahead.
