50 Ton Large Crawler Excavator
The bucket capacity excavation force is as high as 246KN, achieving a significant improvement compared to models of the same tonnage. The maximum excavation force reaches up to 290KN, ensuring efficient and powerful excavation performance. The equipment features flexible rotary performance with a rotational speed of 9.3r/min, effectively reducing the time per operation cycle and enhancing continuous operation efficiency. Equipped with a 650L large-capacity fuel tank and featuring excellent fuel-saving technology, it can extend the operation time by 20%, meeting the demands of high-intensity continuous construction.
Product Description:
The 50-ton large crawler excavator is equipped with an advanced electro-hydraulic control system and a 5.7-inch high-resolution LCD liquid crystal display screen. The picture brightness and resolution effect have been significantly improved, and it supports dynamic image display, making the overall operation information of the machine more comprehensive and intuitive. Key data is refreshed in real time, enabling continuous and precise monitoring of equipment status.
The engine ECU of this model communicates with the controller in real time via the CAN-BUS bus, achieving more precise power control and comprehensive and efficient data acquisition, significantly enhancing the overall operational efficiency of the machine. With advanced manufacturing techniques, the product features outstanding protective performance and can maintain stable and reliable operation even under harsh working conditions.
In addition, the SH500-9 model also adopts a telescopic track chassis design, which is not only convenient for transportation and transfer but also can flexibly adapt to various complex working scenarios.

The 50-ton large crawler excavator builds an intelligent fuzzy control system with the multi-neural adaptive PDI algorithm as the core. This algorithm can automatically shield the integration effect when the systematic error is large, and intelligently introduce integration control when the error is small. It not only effectively suppresses the integration saturation phenomenon but also significantly accelerates the dynamic response speed. While enhancing the adaptive regulation capability, the system also optimizes the steady-state accuracy, thereby comprehensively improving the static and dynamic performance indicators of the entire machine, and ultimately achieving online energy-saving intelligent control of excavators.
