In the railway construction project in Malaysia, Shantui SE350 excavator equipped with reinforced buckets are involved in foundation excavation and site leveling on both sides of the railway. Equipped with Weichai engines and Linde hydraulic components, the equipment optimizes control strategies, reduces back pressure, and increases bucket capacity design. This ensures that the fuel consumption is controlled within 22L/h for SE350 and 35L/h for SE500 while meeting construction speed and force requirements. The structural components are reinforced, with the boom pin support area increased and the swing motor mounting seat adopting curved welds to ensure heavy-load reliability. The cab is equipped with an air-suspended seat, providing a wide view, and intelligent configurations such as a 10.1-inch smart touch screen and rear camera, making operation convenient and comfortable. With the advantages of strong power, low fuel consumption, and good stability, customers have successively purchased multiple Shantui excavators and recommended other customers to purchase them.
