Product Description:




●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.
