The main technical level of Down-Hole Drilling Rig, with nine patents, has remain the international advanced level.

The main technical level of Down-Hole  Drilling Rig, with nine patents, has remain the international advanced level. The notable features are as follows:

1. Integration of drilling mechanism, air-compressed supplying system and power group provide improved maneuverability, energy saving and high efficiency.

2. Parts worldwide procurement, chose from well-known brands, actualize the higher efficiency and reliability.

 

3. Pilot handles control all the machine operations, the various movements and speeds can be adjusted at any time. All of above make sure the machine operate normally and accurately.

4. High reliable crawler traveling system, hydraulic motor driving drilling rod ,and hydraulic cylinder supported sliding rack optimize working efficiency and machine adaptability.

5. Hydraulic disassembly mechanism for impact ,drilling system ,drilling bit.

6. High effective dust collection device and the anti-hoisting device, which is the original patent at home and abroad, improve the working environment effectively.

7. High effective dust collection device and the anti-hoisting device, which is the original patent at home and abroad, improve the working environment effectively.

8. The domestic unique auto block-prevention mechanism can lift the drill stem automatically when the stem got stuck, making the stoppage much less than before.

9. The patent technology self-adaptive control to the force on the drilling process, cooperating with the auto-sensing control to various rock conditions and decrease the block faults.
