The advantages of XZ680A HDD horizontal directional drilling machine

1. The rack pinion push and pull. The transmission is smooth and reliable. The power head spindle floating improve the service life of drill pipe thread;

2. The line-control proportion of walking system ensures the security of the walk;

3. The slurry flow shift stepless speed regulation system is more convenient to adjust the flow of the slurry, save the slurry and reduce the environmental pollution caused by slurry flowing;

4. The push-pull pressure shift stepless speed regulation system adjusts the push-pull pressure according to different working conditions, fast and convenient, which also can protect the drill pipe thread from being damaged.

5. 45 ° rotating cabin can be realized, which make the tractor driver in driving indoor observe the vice action more conveniently. At the meantime, it improves the interior assembly and increases the radio audio and USB port and improve operation comfort.
