Recently, the embankment construction of the upper reservoir dam at the Xingcheng Pumped Storage Power Station in Liaoning Province has successfully advanced to the critical elevation of 410 meters, marking a major milestone for this key national project under the 14th Five-Year Plan. Throughout the construction process, SHANTUI SD34-G bulldozers and SR26-G rollers have operated continuously and efficiently, participating in the entire dam embankment construction. They have provided reliable equipment support for the safe and high-quality progress of the project.

With a total installed capacity of 1,200 MW, the Xingcheng Pumped Storage Power Station is projected to generate approximately 1.204 billion kWh annually upon completion. This project holds significant strategic importance for optimizing the Northeast China power grid structure and enhancing renewable energy integration capacity. The project's reservoir dam is an asphalt concrete-faced rockfill dam with a maximum height of 106 meters and a total embankment volume of approximately 5.63 million cubic meters. It involves large-scale construction, complex processes, and stringent quality control requirements.

Since the commencement of dam filling operations, the project site has faced persistent challenges including complex material sourcing conditions, limited construction areas, and severe cold temperatures. SHANTUI equipment, leveraging its stable and reliable performance along with outstanding adaptability to working conditions, has undertaken critical tasks in key filling and compaction processes, ensuring stable and controllable construction progress and engineering quality.

During high-intensity dam material pushing and shaping operations, the SD34-G hydraulic dozer demonstrated outstanding comprehensive performance. Equipped with a Weichai WP13 electronically controlled engine, this model supports dual-power mode switching, intelligently adjusting output based on workload to ensure ample power while effectively reducing fuel consumption. Paired with an efficient hydraulic torque converter and SHANTUI's proprietary undercarriage system, the machine delivers strong traction and stable travel, meeting the demands of continuous, heavy-load construction. The spacious, comfortable cab and low-noise design also provide operators with an optimal working environment.

The matching SHANTUI SR26-G full-hydraulic single-drum roller serves as critical equipment for ensuring dam material compaction quality. Utilizing a Linde heavy-duty electronically controlled hydraulic system, it delivers smooth vibration start/stop and precise closed-loop frequency control, guaranteeing uniform compaction and density compliance across all fill layers. Its intelligent control system, comfortable cab, and extended maintenance intervals further enhance construction efficiency and equipment uptime.

Operating under complex geological conditions and harsh climatic environments, the SD34-G bulldozer and SR26-G roller maintained high availability and low failure rates, earning unanimous recognition from the construction team. From dam material transport and shaping to layered compaction, the integrated equipment demonstrated stable and continuous performance, becoming an indispensable force in the Shangshui Reservoir dam construction process.

Participating in the construction of the Liaoning Xingcheng Pumped Storage Power Station represents another instance of SHANTUI equipment deeply serving national energy strategies and green infrastructure development. Moving forward, SHANTUI will continue advancing the R&D and application of efficient, intelligent, and green construction equipment. With more reliable products and professional services, it will support the high-quality construction of major national projects and clean energy initiatives.
