Main features:
1. The section of main lifting boom is designed to be U-type. The main boom consists of five main sections. The maximum lifting height is 43m, which shows dynamics performance of high-tension steel, which trends to be more distributing. Its performances of flex resistance and anti-rotation are improved significantly.
2. The embedded type of slider structure and the overlapping parts of front and rear section of the boom are better power distribution, to some degree, reducing stress concentration at large which improves the lifting capacity.
3. The normally closed type of slewing brake system, equipped with designed typically rotary buffer valve, which makes things come true, such as fast open or stop, stable buffer when it accelerates to stop.
4. Its H-type outriggers and the equipped fifth outrigger make 360 slewing working. Each agency could operate its speed freely. It is convenient for people to operate stably and reliably.
5. The inner container of outrigger reinforces the design by simulating, offering the optimum horizontal span of outrigger, ensuring the working stability.
6. The optimizing hydraulic system of the superstructure, sensitive and reliable, owning good micro-performance, the system of which is less overflow, is high-efficiency.
7. Electro-hydraulic proportional control system adopts pressure compensation. Load back feed protect the working speed from the influence of loading changement, working in good stability, which makes power loss of system a little
8. The advanced height limit and over-winding protection equipments, the buffer valve equipped in fully hydraulic system, which ensures slip as well as micro-motion freely and stably.
9. Self-automatic load moment limiter could control the function of overloading and also length or angle sensor function.
10. Planetary gear main and auxiliary winch makes heavy low-speed, light high-speed reachable. Besides, many choices of polarity and non-polarity speed improve the working efficiency significantly.
11. The spacious inside space, the luxurious inner decoration, the board perspective, steering wheel, the seat pedal and also operating handle, all of which could make our operate more convenient and swift.
12. The beautiful appearance and the suitable features of the operating cab, board perspective, dust tight and sound reduction, the big hydraulic display and anti-seismic pressure indicator that could show the working condition at anytime, ensuring the working safety.
