  • MAIN PRODUCT PARAMETER

1. The leading overall transport full hydraulic rotary drilling rig, can change transport state into working state rapidly;

2. High-performance hydraulic system and control system can realize the machine efficient construction and real-time monitor;

3. High security, designed in strict accordance with European Union safety standards EN791. Meet the requirements of dynamic and static stability.

4. Unique structure of folding mast can ensure the overall transportation and reduce the transport size;

5. Advanced design of rotary angle displacement output mechanism and central rotary joint output angular displacement can get higher reliability;

6. Innovative drilling bucket depth measurement system can show higher accuracy than the average rig;

7. The function of main winch bottoming protection and priority controlling can make the operation easier;

8. The reversible use of the driving head’s chain can extend the service life;

9. Multi-stage damping technology of the driving head can ensure the whole construction more stable;

10. The technology of mast automatic verticality can make the vertical accuracy of the hole higher;

11. The innovative design of luminous hot wheel can ensure construction in night more safety;

12. The humanized design of chassis back can increase storage space efficiently;

13. New design of two-stage operating interface can make it more convenient to operate.
