The new E-Series of excavator includes the 922E and 925E versions – upgrades from the current 922LC and 925LC machines – and the larger, all-new 930E machine.
The smaller 922E has an operating weight of 22,000kg and a maximum digging depth of 6595mm.
The 925E has an operating weight of 25,500kg and a maximum digging depth of 6925mm.
The 930E has an operating weight of 31,300kg and a maximum digging depth of 7300mm.
“Each new E-Series excavator has been built on the values that LiuGong strives to achieve in all our machines: reliability, safety and service,” said Xiaorong Zeng, LiuGong’s excavator product marketing manager.
All are powered by a Stage IIIB Cummins 6.7 litre engine. Net power is 117kw@2000rpm for the 922E; 129kw@2000rpm for the 925E; and 147kw@1900rpm for the 930E.
Compared with the previous 922LC and 925LC machines, the 922E and 925E have reduced fuel consumption by 8% and 5% respectively, and feature increased bucket digging forces of 5% and 11.8% respectively.
Six selectable working modes are available to optimise performance and fuel consumption depending on the type of work being carried out: Power, Economy, Fine, Lifting, Breaker and Attachment. In addition, the machines have a two-speed automatic shift, enabling them to go from fast in normal conditions to slow when driving over obstacles.
Should extra power be required while excavating, a power boost control system can be activated to temporarily increase breakout force by 7% for a greater lifting capacity.
In the cab, the field of view has been widened with bigger windows and an enlarged skylight and there is a new shock absorber to reduce vibrations.
