1、 Main features:

1. The top drive power head adopts foreign technology, with a structure of dual motors and mechanical gear shifting, with a large speed range and high torque at the low-speed end. It is equipped with different motors, and the maximum end torque can reach 11000NM, which is suitable for different drilling methods and meets various construction methods.

2. The power head has high rotational accuracy and smooth operation, which can better demonstrate its advantages during deep hole drilling.

3. The maximum speed of the drilling rig is 1020rpm, with a torque of 670NM. The high-speed end has a large torque, making it suitable for deep hole drilling.

4. The lifting system adopts a hydraulic cylinder chain doubling mechanism, which provides a long process and facilitates long core extraction operations.

5. The power head adopts an automatic opening method, combined with a clamp and a release device, which can easily and quickly complete the rope core taking operation, eliminating the traditional secondary platform operation. It has a high degree of automation and is easy to operate.

6. The drilling rig has a fast lifting speed, saving a lot of auxiliary time. When fully drilling, it is easy to clean the hole and improve drilling efficiency.

7. The main tower guide rail adopts a V-shaped structure, and the connection between the power head and the main tower has high rigidity, smooth high-speed rotation, and high core extraction rate.

8. The main winch adopts imported products to improve stability and reliable braking.

9. The hollow drum rope speed of the rope core taking winch reaches 205m/min, reducing auxiliary time.

10. The drilling rig is equipped with clamps and shackles, making it easy and fast to disassemble the drill rod, reducing labor intensity.

11. The drilling rig is equipped with a power head tachometer and a drilling scale, making it convenient for users to select parameters.

12. The drilling rig adopts backup pressure balance for feeding, which can easily understand the pressure value at the bottom of the hole and improve the life of the drill bit.

13. The hydraulic system of the drilling rig is reliable, and the mud pump is controlled by hydraulic pressure. Various operations of the drilling rig are centralized, making it easy to handle various underground accidents.
