en.Wedoany.com Reported - The boiler roof girders for Unit 1 of the Shaanxi Coal Miluo 2×1000 MW coal-fired power generation project in China have been successfully lifted into place. The completion of this milestone marks a breakthrough in the boiler steel structure installation, laying the foundation for the subsequent installation of the boiler roof deck and heating surfaces. As a key regional energy supply project, this project involves the simultaneous construction of two million-kilowatt ultra-supercritical units. Once completed, it will optimize the local energy supply structure and promote regional green and low-carbon development.
A total of four boiler roof girders were lifted for Unit 1 this time, among which the upper girder BL-2 was the heaviest, weighing 124.05 tons, with a top elevation of 127.76 meters after being placed into position. The construction team used a JLP3600 tower crane (with a maximum rated lifting capacity of 200 tons) for single-crane, one-time lifting, ensuring the precise placement of each girder. Faced with challenges such as large high-altitude spans, heavy component weight, high installation precision requirements, tight schedules, and extensive cross-operations, the project department planned and coordinated in advance, scientifically prepared specialized plans, rationally deployed various construction resources, repeatedly simulated the lifting process, and accurately determined the crane's positioning and travel path. Simultaneously, safety responsibilities were strictly implemented, with full safety and technical briefings conducted for all personnel before operations, full-process stand-by supervision during operations, and point-to-point closed-loop control to ensure the lifting operations proceeded smoothly and orderly.
In the next step, the project department will continue to closely monitor schedule milestones, strictly adhere to safety and quality bottom lines, and advance subsequent installation tasks as planned, striving to build a high-quality million-kilowatt thermal power project.
