Recently, more good news came in from the site of the Shaanxi Yueneng Fine Chemicals project, which is being constructed by Shaanxi Huajian Lifting Company. After 2 hours and 12 minutes of precise operations, the 347-ton EO reactor feed heat exchanger was successfully lifted into place. This marks the successful completion of a key milestone in the construction of the ethylene oxide plant, laying a solid foundation for the subsequent installation work. It is reported that this lifting operation represents a critical milestone in the construction of the entire ethylene oxide plant. The equipment itself is quite heavy, and it needs to be installed within a steel structural framework, requiring high precision in installation. To carry out the lifting task with precision, the project’s lifting team carefully evaluated various lifting plans; ultimately, it was decided to use a 650-ton crawler crane as the main lifting device, operating in HDB 72-meter boom mode, with a 250-ton crawler crane used for assisting with the lifting process. Once lifting began, the main crane and the auxiliary crane worked together to lift the equipment, turning it from a horizontal position to an upright one. Afterwards, the 250t auxiliary crane released its hook, while the 650t crawler crane rotated clockwise; by lifting and lowering the hook, the equipment was guided through the top of the frame and placed precisely on the foundation. The Yueneng 1 million tons per year high-end chemicals and new materials project is located in the Yushen Industrial Zone, covers an area of 1,500 mu, and has a total estimated investment of 10.315 billion yuan. Once the project is completed and put into operation, it is expected to generate annual revenue of around 8 billion yuan, producing nearly 10 types of chemical products. Shaanxi Huajian Lifting Company was responsible for lifting 63 pieces of large-scale equipment for this project, with a total weight of 10,297.8 tons ； 39 oversized short-haul trucks, with a total weight of 4,686 tons. The lifting and installation of 11 units have been completed so far.
