DF H 4 1000m Hydraulic mud rotary diamond soil investigationd drill machine core mining drilling rig

 The leading core drill rigs in the developed countries are full hydraulic operated type, which adopts the technology of wire-drawing core with a diamond tip. This type of drill rig is also the main developing trend in the field of drill rig technology and related equipment. Under the international and domestic trends, our factory has developed the DF-H-4 Full Hydraulic Operated Core Drill Rig. 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.

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

 Established in the 1970s, Zhengzhou Defy has grown into one leading drilling rig manufacturer in China, specializing in drilling rig technology R&D, manufacturing, etc. We spark on a 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, Tanzania, Zambia, South America, Peru, Zimbabwe, etc.
 
Every customer is very welcomed to our factory for visiting the drilling rig,  talking onsite and details. 

 How to choose a suitable drilling rig? 

1. What will you do using the 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 the 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 machines and prices. If you have special demands, please tell us ahead.
