Feature

1. The whole machine performs well in all parameters: high speed, large torque, fast push and pull, good controllability, energy saving and high efficiency, smart and convenient.

2. The power is Dongfeng Cummins electronic injection diesel engine, which has strong power, reliable performance, high power, low noise, low fuel consumption and other characteristics. All hydraulic parts adopt top international products, with reliable performance, high efficiency and small size.

3. The main shaft rotation and push-pull adopt closed systems, and the mud and auxiliary systems adopt load-sensitive systems. All systems used are volumetric speed control systems, which have high transmission efficiency, low heat generation, and low oil temperature, reducing power loss, saving energy and reducing emissions.

4. The rotation and push-pull are driven by four Danfoss closed pumps respectively, with high output speed and power, and high construction efficiency. The feed speed is fast, the fastest can reach 40 meters/minute, the position of the power head is displayed in real time, and the automatic deceleration buffer is in place. The hosting efficiency is high, and the speed of adding drill pipe is fast.

5. Both rotation and push-pull use low-speed and high-torque motors, with large starting torque and strong impact resistance. One-button control in the cab allows quick and power-assisted opening without external operation, making it convenient and reliable. The push-pull system is equipped with international leading technology: free wheel system, one-button intelligent control of push-pull force and speed, intelligent switching between high, medium and low speed, minimizing system power loss and improving construction efficiency.

6. The rotation and push-pull pressure of the power head are infinitely adjustable and can be adjusted according to different strata. The operation is convenient and quick, and can effectively protect the drill pipe and drilling tools.

7. It adopts Danfoss original imported controller and seven-inch color LCD display, with intelligent switching of work interface modes. The system has fast response time, high efficiency, safety and reliability. The host has complete parameters, a friendly human-machine interface, a high level of intelligence, and the construction is more scientific and efficient. According to different working conditions, the power of each action is automatically allocated to maximize construction efficiency. Double operator cab, comfortable operation and wide field of view.

8. The rotating system is equipped with anti-impact overload protection and an external flushing integrated system, as well as an active oil replenishment system to improve system safety and reduce construction failure rates.

9. Large chassis design, large climbing angle and high construction stability.

10. The power head is equipped with a self-floating mechanism of the involute spline of the shackle spindle, which cooperates with the middle drill pipe bracket and has good neutrality, making it easy to unscrew the drill pipe and reduce wear on the drill pipe thread.

11. Remote wired walking remote control, proportional control of walking speed, high and low speed adjustment, remote control of tower lifting and outriggers, convenient for getting on and off the vehicle, safe and reliable.

12. The central holder is equipped with a bracket system that automatically adjusts the center of the drill pipe. Keep the drill pipe and the spindle coaxial, reduce the impact of the drill pipe vibration on the spindle, and avoid the breakage of the spindle.

13. Cabled or cableless steering instruments can be used for guided drilling, which is suitable for various working conditions.
