Liugong 920e New 21.5 Ton Crawler Excavator with Hydraulic Pipeline
1. 920E hydraulic excavator is a brand new product independently developed by drawing on advanced technology from similar products at home and abroad, combined with years of professional accumulation and market experience summary. This product comprehensively overcomes multiple key core technologies of a 20 ton hydraulic excavator, with characteristics such as fast speed, low fuel consumption, good human-machine engineering, easy operation, and easy maintenance. It is widely used in agricultural water conservancy, civil engineering, municipal construction, and oil pipeline engineering. 920E also has good working conditions and environmental adaptability, which can meet different operational requirements such as excavation, loading, crushing, and shearing. It has a plateau adaptive system and is also resistant to high temperatures, which can adapt to environmental temperatures of 50 ºC.
2. The fully electronically controlled engine complying with the national three-stage emission standard is adopted, the power curve is customized, the common speed is set in the low speed and high torque area, the torque reserve is increased by 15%, and the power is sufficient. The fully electronically controlled Common rail engine technology increases the fuel utilization rate by 5%, which is more energy-saving and environmentally friendly.
3. The upgraded hydraulic negative flow system has high working pressure, low internal pressure loss, reduced throttling, easy selection, easy operation, and standard buffer valve, ensuring stable and low impact of the entire machine
4. Control system optimization, subdivided into four operation modes according to different operating conditions, P, N, B, and T, with stronger targeted working conditions and more precise control; Common gear optimization, lower fuel consumption, with the same efficiency, fuel consumption can be reduced by 5-7%.
