Product Description:

Performance  

●High-performance hydraulic  system and control system in cooperation with Tianjin University CNC Hydraulic  Institute of Technology, which can realize the machine efficient construction  and real-time monitor;

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



■Imported CAT329D chassis,  with skilled technology ,reliable and stable performance;

■Optimized structure of  luffing mechanism and mast can extend structural components’ service life  greatly;

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

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

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

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

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

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

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

■The innovative design of  luminous hot wheel can ensure construction in night more safe.

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

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