At a significant contemporary open-pit coal mine in western China, the Shantui SE980LC big excavator has just successfully finished field adaption and application verification. The construction crew and operators have praised the machine for its great operating efficiency, dependable operation, and outstanding energy-saving performance under heavy-duty situations.
As one of the leading large-scale modern open-pit coal mines in North China, this site boasts abundant coal reserves and thick coal seams, serving as a crucial base for national energy supply guarantee all year round. The project features heavy construction workloads and tight schedules. The large-scale overburden stripping work puts forward extremely high requirements on the efficiency and stability of construction machinery. Equipped with a 7m³ large-capacity bucket, the Shantui SE980LC works well with other on-site machines, undertaking core tasks including surface soil stripping and material loading.
On-site operators speak highly of its fast movement and superior working efficiency. The air suspension seat brings a comfortable riding experience even during long-hour operation. All filter elements and regular maintenance parts are rationally arranged, which can be inspected and replaced directly on the ground. This user-friendly design greatly simplifies daily maintenance work and saves a lot of servicing time. After long-term operation, the client praises the excavator for its excellent cost performance. It stands out among peer products thanks to its stable performance under intensive working conditions and convenient maintenance. In response to the customer's feedback on fuel consumption, Shantui's professional service team optimized the electronic control program and finely adjusted the power system on site, further improving the overall working efficiency and fuel economy.
Powered by a customized Weichai 6M33 high-power engine with a rated power of 571kW, the SE980LC achieves a 30% power increase compared with other excavators of the same tonnage. Matched with HPR300 large-displacement main pump and full electronic control hydraulic system, the machine delivers high torque at low speed and quick response. It features remarkable energy efficiency, with fuel consumption about 10% lower than similar models. The well-matched combination of Weichai engine and Linde hydraulic system ensures stable continuous heavy-duty operation in mining sites. In addition, the intelligent touch screen, multiple working mode options and intelligent diagnosis system bring simpler and more convenient operation experience for operators.
Since being put into service, the SE980LC has effectively helped the client cut costs on fuel, labor and maintenance, and greatly improved the overall construction efficiency. The client stated that they will continue to purchase Shantui equipment and expand its application scope across the coal mine in the future.
The successful field application fully demonstrates the superior performance of Shantui's large-tonnage excavators and its strong adaptability to mining conditions. It also highlights Shantui's core competitiveness in building green, efficient and intelligent modern mines, providing high-quality equipment solutions for the upgrading of mining engineering machinery.
