Recently, the low-temperature methanol wash unit of the second phase of the Jiangxi Xinlianxin project underwent the most crucial step: the installation of the medium-pressure flash tower equipment. Due to the complex construction environment and limited space on site, in order to ensure that the equipment installation is carried out on schedule, the Jiujiang lifting project team conducted an on-site survey at the beginning of the construction phase. They developed a detailed plan for the disassembly, transportation, and reassembly of the 1250T crawler crane, carefully planning every aspect – from on-site coordination and route planning to the disassembly and assembly of the equipment at the construction site – to ensure accuracy and perfection. It officially started at 17:00 on January 1: 13 team members took turns carrying out the tasks of disassembling and assembling the crawler crane, as well as lifting and assembling it, working overtime without any complaints. Through six days and nights of relentless effort, the 1250T crawler crane lever was successfully completed at 17:00 on January 7. At 15:00 on January 8, the lifting construction of the medium-pressure flash tank, which uses a 1250T main crane and a 300T auxiliary crane, was officially commenced. The tank weighs approximately 128T, has a diameter of 3.8m, and a height of 30m. During the lifting process, it was necessary to lift the medium-pressure flash tank 28m above the steel structure, then rotate it while changing its angle, in order to place it in position steadily. Throughout the entire construction process, the main crane operator, the auxiliary crane operator, and the on-site supervisor worked in close coordination, relying on their excellent skills and strong teamwork. After 1.5 hours, the equipment was accurately positioned; the lights came on, and the “first crane” in Jiujiang for 2025 was delivered safely.
