The 25th National \"Safety Production Month\" in 2026: Everyone should talk about safety and be able to handle emergencies; risks and hazards need to be identified and addressed. -------------------------------------------------- It is understood that this lifting operation falls under the category of high-risk construction tasks, with complex on-site conditions and extremely high technical challenges. The working area in the project’s equipment zone is narrow, resulting in extremely limited space for the placement of two machines and for the crane’s movement. At the same time, the lifting equipment in this project is of considerable size; after completing tasks such as insulating the tower and installing the pipelines attached to it, the total weight of the equipment to be lifted amounts to 92 tons, and its total height is 48.2 meters. This poses high demands on the planning of the lifting strategy, the positioning of the machinery, and the coordinated efforts of the personnel involved. To ensure the safe, high-quality, and efficient progress of the lifting operations, the project team planned in advance and made comprehensive arrangements, detailing various tasks such as the delivery of large-scale equipment, preliminary prefabrication, and preparations for lifting. The main body of the T-2305 benzene recovery tower was successfully delivered to the site on June 13; the following day, the pipelines attached to the tower as well as the associated materials were also delivered, creating favorable conditions for subsequent concentrated construction work. To address the challenges posed by limited space and restricted movement capabilities at the construction site, the project team scientifically optimized the construction plan. They ultimately decided to use an XCMG XCA 700-ton truck crane as the main lifting device, along with an XCA200L8 truck crane as an auxiliary device for lifting. The operating radius, rated load, and location of the crane stations were carefully calculated; many tasks that required working at heights were carried out on the ground, thereby avoiding safety risks associated with high-altitude work and effectively reducing the time needed for concurrent operations at the site. During the lifting operation, the operators of the two large cranes worked in close coordination under unified command, ensuring that the load was under control throughout and that the structure remained stable, thus enabling the precise installation of the tower to be completed successfully.
