On December 12th, with the final instrument air booster installed successfully, the installation work for the two compression heat adsorption regenerative dryers and one instrument air booster in Nantong Blue Sea New Materials’ air separation and air compression system, carried out by the Nantong Blue Sea New Materials project team of the Fifth Branch, was completed successfully. This laid a solid foundation for the subsequent system integration, testing, and commissioning of the project. The two compression heat adsorption regenerative dryers each have a volume of 8.24 m³; their inner diameter is 2.1 m and their length is 3.33 m. Each of them weighs 12 tons, and they serve as the \"lungs for purification\" in the air preprocessing system” ； The instrument air booster, with a length of 8.2 meters, a width of 2.8 meters, and a weight of 18 tons, represents a major challenge in terms of lifting; its accurate positioning is directly related to the stable operation of the subsequent gas delivery system. What makes things more challenging is that all equipment must be lifted inside the already installed steel structure factory building; the working radius is strictly limited, which imposes high demands on the positioning of the cranes, the routes for transporting the equipment, and the control of the lifting posture. To address the challenge of lifting skid-mounted equipment in confined spaces, the project team formed a task force that, after multiple rounds of on-site inspections and simulation studies, developed a tailored lifting plan. The 200t folding arm crane selected for this purpose, thanks to its ultra-high-strength alloy frame, four-leg structure with a large span for support, and high-precision intelligent control system, is capable of dynamically adjusting the lifting parameters in real time ； Its flexible amplitude adjustment capability and ultra-high rated load allow it to move precisely among densely packed components. In addition, the project team designed high-strength specialized balance beams and professional lifting equipment, employing a distributed load optimization approach to distribute the lifting load evenly across the equipment’s lifting points, thereby effectively preventing damage to the integrated components due to excessive local stress.
