1. Equippedwith expert chassis, the width range of the crawler is 3500-4800mm, wheel span is 5175mm, and this highly assured the transportation convenience and improved stability during construction.
2. Optimized turning structure with high strength, reasonable layout, which is very convenient for maintaining.
3. All hydraulic operation system, high stability and reliability.
4. Integrated and intelligent control system with convenient man-machine interaction, enables the dynamic display; the display of failure information and I/O testing function ensures high reliability and safety.
5. Self-researchgrab can meet the need of complex geological conditions, the low center of gravity, long guiding distance, big grabbing force (with standard 1400kN pushing force), and equipped with 12 adjusting devices ensures the high efficiency and precision(the procession can reach 1/500).
