With the addition of Cummins Tier 4 Final engines, LiuGong has launched an update to its E-Series excavators. The new emissions-compliant machines include the 915E, 922E, 925E, 930E and 936E. At 30 metric tons, the 930E represents a new size class for LiuGong.
The new excavators also feature quick couplers and auxiliary hydraulics with one or two pump flows. “Excavators are no longer just for digging dirt,” says Michael Watt, excavator product manager. “Customers want to be able to do demolition and put grapples and hammers on them.”
The booms on the new models were beefed up to reduce flexing and increase longevity. Extra steel was also added under the slew bearing to improve durability and reduce the need for extra counterweight bulk, says Watt. The LiuGong excavators also have some of the longest roller frames in the industry, says Watt, which helps with stability.
LiuGong redesigned the cabs, making them ROPS certified and increasing the glass and visibility by 7 percent. The cabs also sport a new, multi-function monitor and extra legroom. A rear-view camera comes on whenever the excavator is traveling and can be manually activated anytime the operator wants.
An auto-idle speed function and Intelligent Power Control help conserve fuel. Operators can choose either ISO or SAE style control patterns by turning a valve in the engine compartment. Access to the fuse boxes, relays and cabin air filter are located on the outside of the machine for easy access and to keep the inside of the cab cleaner during service work.
