50 Ton Large Hydraulic Excavator
This 50-ton large hydraulic excavator delivers powerful and efficient performance with exceptional economy. Its short-arm bucket provides industry-leading digging force in its class, enabling it to tackle tough materials with ease. Combined with faster swing speed, it significantly reduces each digging cycle time. Paired with a large-capacity fuel tank and outstanding fuel-saving design, a single refueling extends continuous operation by approximately 20%, directly lowering your operating costs and enhancing project profitability.
Product Description:
SH500-9 large hydraulic excavator using Cummins engine, with reliable, efficient, low fuel consumption advantages.
Engine power :280Kw, speed: 1850rpm
The electronic control of high pressure fuel injection is used to optimize fuel injection and reduce fuel consumption. Reduce fuel consumption and noise by reducing excess engine rotation in light operations with synchronous control.

Advanced electro-hydraulic system
With 5.7 inch large screen LCD LCD display, the machine information display is more comprehensive and intuitive, improve lumen and screen resolution, and provide dynamic images. Important information is displayed in real time, and the running status of the machine can be monitored in real time.
The engine ECU and the controller adopt CAN-BUS communication, the power control is more accurate, the data acquisition is 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 the system can run stably and reliably under harsh working conditions.
The multi-neural derived adaptive PDI algorithm is adopted as the basic algorithm of fuzzy control. When the system error is large, the integral link is cancelled, and when the error is small, the integral link is introduced, which can quickly eliminate the error, avoid integral saturation, speed up the adjustment process, strengthen the system adaptability, and steady-state error, so that the static and dynamic performance indicators of the system are ideal, and the online energy saving control of the excavator is realized.
