Power Core: Cummins QSM11 Engine, Guarantee of High Efficiency and Low Fuel Consumption
The large-tonnage crawler excavator is equipped with a Cummins QSM11 engine. Relying on electronically controlled high-pressure fuel injection technology, it achieves precise fuel supply, greatly reducing fuel consumption while improving the stability of power output. The engine has core advantages of reliability, high efficiency and low fuel consumption, and can easily cope with complex environments such as high altitudes and high temperatures. It provides continuous and strong power support for the heavy-duty operations of large-tonnage crawler excavators, fully meeting the core needs of global users for high-efficiency and low-fuel-consumption equipment.
Hydraulic Precision Control: Kawasaki Main Pump + Toshiba Main Valve, Precise Response to Heavy-Duty Needs
The hydraulic system adopts the golden combination of Kawasaki main pump and Toshiba main valve. The Kawasaki main pump has significant advantages of high efficiency, high response and large displacement, and also has rich control methods and high power output density. Its high self-priming capacity ensures stable power transmission, and high reliability is suitable for long-term heavy-duty operations. The Toshiba main valve is equipped with multiple intelligent control functions such as straight-line travel circuit, boom priority, swing priority, bucket confluence, boom regeneration technology and arm/boom load holding valve, enabling the large-tonnage crawler excavator to perform precise and coordinated actions in complex operations, greatly improving operation efficiency.
Structure and Operation: Heavy-Duty Optimized Design, Comfortable and Efficient Operation Experience
The crawler excavator excels in structural design. High-stress areas adopt high-strength steel plates, the shaft seat area uses forged parts, and the middle section is welded with a large-section base plate, which greatly improves the load-bearing capacity and durability of the equipment, easily coping with extreme heavy-duty working conditions such as mines. At the same time, it is equipped with a spacious and comfortable driving and operating environment, with an optimized operation layout, effectively reducing the labor intensity of operators. As the flagship large-tonnage crawler excavator of Jining Shitian Heavy Industry, the product has undergone rigorous testing from core components to detailed design, ensuring stable and reliable operation in various heavy-duty scenarios.
With the core advantages of high efficiency and low fuel consumption and the reliable performance of golden configuration, the Jining Shitian SH520-9 large-tonnage crawler excavator injects new vitality into the global heavy-duty construction field and demonstrates the strength of China's construction machinery manufacturing.
