21T Horizontal Directional Drilling Machine HDD Electric Design

Main Performance Characteristics:

1. The rotation and thrust is equipped with USA Sauer cloded-circuit system, which is efficient, stable and reliable,

Rotation motor is originally imported French Poclain brand which is famous all over the world. and push pull

motor is Germany Rexroth ehich increses work efficiency more than-20%, and totally save about 20% energy

compared with traditional system.

2. Hydraulic control is adopted for rotation and push&pull, reducing the faults resulted from the aging of electrial

components, realizing more stable and reliable control and quicker response.

3. It is equipped with Cummins engine specialized in engineering machinery with strong power.

4. Driving head reserves reinforced power (push&pull force), which can be incresed to 1200KN, which ensures

the safety of the large diameter pipe construction.

5. Four bar linkage luffing structure is adopt for main girder , which highly increases entry angle range and

ensures the large angle and rig tracks are not off ground,improving the safety performance.

6. Wireless control walking system ensures the safety for walk and transfer.

7. Full lifted is is convenient for loading and unloading drill rod. which can greatly reduce the workers labor

intensity and improve work efficiency.

8. With φ102×4500mm drill rod, the machine fits medium field area, meeting the requirement for high

efficiency construction in small downtown district.

9. Main hydraulic components are from the global first class hydraulic manufacturers, which greatly improved

the reliability of product ferformance and safety.

10. Electric design is reasonable with low failure rate, which is easy to maintain.

11. Push&pull contains rack and pinion push-pull system, which is good for high efficiency, long lifespan, stable

work and maintainance is also convinient.

12. Steel track with rubber plate can be loaded heavily and walk on all kinds of roads as well.
