Product Description

Horizontal Directional Drilling Machine 
  
[Main Performance Characteristics]
  
1.Main hydraulic system. High pressure electric control open-circuit system, compared to closed-circuit system, there is no pressure difference loss caused by oil-adding pressure, the system is more energy-saving and environmentally friendly, and rig work ability can be further enhanced.
2. The machine is equipped with two diesel engines, and one can choose one or two engines to work according to different conditions, so energy is saved. If one of the twin engines breaks down, the other one can still be operated normally (with the same force and low speed), which can greatly improve construction safety.
3. Proportional linear stepless regulation is adopted for driving head rotation and push & pull speed.
4. Front and back clamping can be separated, and the clamping floats in the whole process.
5. It is equipped with φ127×9600mm, φ140×9600mm or φ168×9600mm drill pipe. Floating spindle can further protect the drill pipe thread.
6. Floating girder is good for loading, unloading, climbing and transportation, which is convenient for adjusting entry angle, and the power head length can reach 11 meters, which can effectively protect clamps.
7. Wide steel walking track is convenient for loading and unloading directly in position without taking apart.
8. Two seats are in operation cab, spacious and comfortable, and can be lifted, rotated, with open field of vision.
9. Drill pipe bracket in the middle increases the accuracy of drill pipe loading and unloading, which can highly improve working efficiency.
10.Main control valve. The main switch valve is independently designed according to rig construction conditions, with patent protection. The simple and reliable structure can ensure smooth operation. Big drift diameter design is characterized with smaller throttling loss, smaller heating power, more energy saving, compact shape etc. More reasonable power system structure can improve push-pull speed on the condition of not affecting rig torque and push-pull force, hence meeting speed demands in different construction conditions.
11. To enhance the executing mechanism ability, hydraulic system is designed in conformity to large flow and high pressure. Our self-designed inserting control valve group reacts fast and reduces 50% pressure loss in hydraulic system.
12. Self-designed and developed, combined electronic controlling system realizes its adaptive control to different working conditions and different geologic strata, improving 30% efficiency of construction.
13. Liquid crystal man and rig exchange system can monitor rig condition at any time, which can adjust rig work and alarm parameter, making operation simpler and more comfortable.
14. Rational and effective cooling system ensures safety, reliability and efficiency of system, extends motor using lifespan, and avoids motor damages.
15. System is configured with both auto-operation and man-operation. Auto-operation could timely adjust the running parameter according to the strata situation and automatically adjust the rig for rig and drill rod protection.
