LIUGONG 921E Crawler Excavator

Adopting a new generation of sub-pump system, the two pumps are independently controlled according to different working conditions, keeping the efficiency of the original system equivalent;

Reduce energy loss, improve operability, reduce overall fuel consumption by 5% to 13%, operate more smoothly, and move more precisely; standard 1.1m³ earth bucket, bucket shape and double side teeth are optimized, easy to cut, higher loading efficiency, more applicable Earthmoving conditions;

Economy gear consumes 14.2~38.5% less fuel than competing products, and the fuel efficiency is 11.8%~21.3% higher than competing products. Structural parts adopt a large-section structure design, and the boom and stick supports are made of integral steel castings to reduce stress and are completed by robots. Welding to improve the strength and reliability of structural parts
