Product Description:
50 tons large crawler excavator has an advanced electro-hydraulic system. Excavator adopts 5.7 inch large-screen LCD LCD display, the machine information display is more comprehensive and intuitive, improves lumen and screen resolution, and provides dynamic images. Real-time display of important information to achieve real-time monitoring of machine running status. 50 tons large crawler excavator engine ECU uses CAN-BUS to communicate with the controller, making the power control more accurate and the data acquisition more comprehensive and timely. The working efficiency of the whole machine is greatly improved. Advanced production process to ensure that the product has a high level of protection. Ensure that the system can operate stably and reliably under harsh conditions. In addition, the SH500-9 adopts a retractable track frame, which is convenient for transportation and can also be applied to various working conditions.
50 tons large crawler excavator adopts multi-neural derived adaptive PDI algorithm as the basic fuzzy control algorithm. The algorithm eliminates the integral link when the system error is large, and introduces the integral link when the error is small, so as to quickly eliminate the error, avoid integral saturation, accelerate the adjustment process, enhance the adaptability of the system, and steady state error, so as to make the static and dynamic performance indicators of the system more ideal, and realize the online energy saving control of the excavator.
