main technical features:

1 For the first time in China, the computer integrated control electric proportional operation system is adopted. The advanced CAN-bus data bus technology is used in the system. The electronic signals of all important electronic components of the crane, such as length sensor, angle sensor, position sensor and control handle, are transmitted to the computer through the CAN-bus bus for centralized processing, and all information parameters of lifting operation are provided through the display screen, Display the working state and process of the crane, realize the automatic control of the crane, greatly improve the safety, reliability and efficiency of the crane, reduce the labor intensity of the operators, and fully reflect the people-oriented design concept

2. The single cylinder bolt type full-automatic quick telescopic system is adopted, and the man-machine dialogue is carried out through the display screen information prompt and manual keyboard operation, so as to realize the full-automatic telescopic of the boom according to the set working mode and logic program and the real-time monitoring of the telescopic state of the boom

3. For the first time in China, the fully elliptical jib is adopted, which greatly improves the anti twisting ability of the jib and can make full use of the mechanical properties of the material. The jib made of ultra-high strength structural steel can significantly reduce the weight of the jib and improve the lifting performance of the jib under a wide range of working conditions. The fully hydraulic double pin internal interlocking system of the electronically controlled jib can ensure the safe, reliable and safe lifting operation

4. The hydraulic system is a pump controlled variable system with electric proportional servo control technology, with partial power regulation and limit load regulation. It is closely combined with the computer integrated control system to greatly improve the control performance of the crane. Good fretting performance, stable action, safe and reliable

5. The independent power system is adopted for the upper carriage. If Volvo's latest water-cooled turbocharged engine is selected, it must effectively control the processing conditions within a certain range. It has the advantages of low speed, high power, high torque, small wear of parts and high work efficiency. The engine power output is automatically optimized according to the load change of the boom through the computer integrated control system and CAN-bus data bus system. The engine power loss is minimized and energy is saved. The ism440e20 EFI engine of Cummins company is used for getting off the train, with emission up to Euro II standard. It has advanced performance and powerful power, reflecting the pursuit of "environmental protection, safety, reliability and advancement"

6. The chassis is a five axle all terrain off-road type, adopting internationally advanced hydro pneumatic suspension technology and full axle steering multi axle drive control technology. The hydro pneumatic suspension system can adjust the height of the chassis from the ground to improve the trafficability of the vehicle; Good shock absorption effect, can realize all wheel steering four axle drive, small turning radius and strong off-road performance; It has the functions of automatic leveling and automatic gear shifting when driving

7. With the black box function, the computer can effectively monitor and record relevant operation status parameters in real time for fault analysis and treatment

8. Multi block combined counterweight is adopted to improve the lifting performance of medium and long boom under large range working conditions. The rotatable counterweight lifting cylinder can realize the self disassembly and assembly of the counterweight

9. Advanced design means such as parametric design, ANSYS finite element analysis and dynamic simulation assembly are adopted to optimize the design of the whole machine and structural parts such as jib, turntable and frame, which greatly optimizes the design parameters of the whole machine, significantly reduces the dead weight of the whole machine, and the running weight of the whole machine is less than 60 tons. For the first time, a major breakthrough in the configuration of five axle chassis on China's 100 ton and above wheeled cranes is realized

10. It is the first time in China to use the reversible control room, which has a wide field of vision and is especially suitable for long arm operation. Using three-dimensional modeling technology and ergonomics principle, the layout, appearance modeling and two room layout of the whole machine are completely designed, which greatly improves the comfort of operation and the maintainability of the whole machine, and reflects the people-oriented design idea

11. The slewing mechanism has controllable free sliding. The slewing mechanism adopts planetary gear reducer and normally closed brake. The external meshing slewing ring is driven by motor. The hydraulic system is equipped with buffer valve, which can realize free sliding and stable micro motion
