LiuGong E-Series Excavators Keep Forging Ahead

At the triennial bauma construction show to be held in Munich later this year, LiuGong will put its full Tier IV E-series excavator range on display. It will include the 915EIV, 925EIV, 933EIV, 939EIV – all of which are fully compliant with European emissions regulations, demonstrating LiuGong’s commitment to the continuous development of its machines. The 9035EIIIA, 922EIIIB and 950EIIIA will also be exhibited to round off this product line. 

Excellent efficiency and low fuel consumption
Customer costs are reduced through a combination of low fuel consumption and reliable machine performance. Every E-series excavator comes equipped with a fuel efficient, world-class Cummins engine that is further complemented by a Cummins-patented turbocharger. This varies airflow to precisely match engine and load demand, resulting in optimal performance.

These low speed, high output torque engines are specially designed for the E-series excavator to ensure their efficient operation. Proven negative flow hydraulics optimise the main control valve, improving the speed of the cylinders’ front end while decreasing the hydraulic system’s damper loss, leading to enhanced working efficiency. The pilot valves match up with the main control valve to offer more precise control.

The E-series also makes use of the Advanced IPC (Intelligent Power Control) system – LiuGong’s own new-generation, computer-aided power control system. Not only does it maximise the engine’s low oil consumption, it also integrates the mechanical, electrical and hydraulic systems, thus achieving high all-round efficiency, economical fuel consumption and improved control.

The E-series machines feature six selectable working modes - Power, Economy, Fine, Lifting, Breaker, and Attachment – to optimise performance and fuel consumption in every situation. Moreover, the automatic speed reduction in neutral gear reduces fuel consumption and noise.

Reliable and sustainable structures
For added durability, the E-series excavators are constructed with thick plates of high tensile strength steel, as well as internal baffle and stress-relieved plates. The boom and arm support structures are designed with large cross-sectional areas and one-piece steel castings to guarantee their long-term durability and high resistance to bending and torsional stress. Standard rock guard plates and vertical guards protect the arm in rocky digging conditions or other similarly rough environments. Finally, ultrasound inspections are carried out to reduce defects and ensure the quality and reliability of these machines.

An H-beam structure is used in the high cross section of the main platform, which is also welded to the collision protection structure to improve its strength, rigidity and service life. The undercarriages of the E-series excavators are built with the mature technology of the X-type reinforced walking frames. They also use the long track beam and crawler system, which provides greater stability and reliability. All these design elements contribute significantly to the excavators’ outstanding stability and durability.

User-friendly working environment
In comparison with the D-series, the cab space of the E-series has been increased by 8.5%, the skylight area by 28.5%, height of vision by 15% and the area of glass on the right-hand side by 10%. These modifications come together to produce a large cab with a wide skylight and broad field of vision.

The E-series excavators also feature a reinforced bridge frame that increases the overall strength of the machine, as well as its impact resistance. ROPS (Roll Over Protective Structure) cabs meet the ISO 12117-2 safety standard, which means that they are fully prepared to handle the unlikely event of a machine roll-over.

The pressurized cabin has been adopted to prevent dust from entering the cab. When the air conditioning (external air import) is in use, customers can increase the internal pressure to prevent the entry of dirt and other irritants.

Optimal maintenance features
The engine oil and fuel filters are integrated at the right rear side of the machines, while the pilot hydraulic filter is located beside the hydraulic tank, providing easy access and maintenance for customers. In addition, both the interior and exterior portions of the air filters can be conveniently removed for cleaning at ground level.

This new generation of E-series excavators were built with the brand DNA of LiuGong. They not only retain the reliability, serviceability and safety of their predecessors, but also function with higher efficiency and lower fuel consumption. With the full range of Tier IV E-series excavators, LiuGong can better meet the requirements of European markets.
