Sleeve lifting
Thread Content
Let me explain in detail: during the installation of the boiler, the upper drum has a center elevation of 8.9 meters, a length of 12 meters, and a diameter of 1.5 meters. At this time, the lifting of the boiler drum was carried out with the top floor still unfinished, and three units with a capacity of 40 MW each had to be installed at once. Is it feasible to use winches and trusses for lifting? If a crane is used for lifting, how should the temporary fixing, support, and alignment of the upper boiler drum be carried out? Urgently seeking expert advice! ! ! :'(
There are various methods that can be used for lifting; the main factors to consider are cycle time, cost, and safety. Lifting using winches or trusses is a viable option, as is using a crane. Given the specifications of the boiler drum, it isn’t considered a large-scale device, so using a crane makes the process faster and simpler. For temporary fixing of the upper drum, a bracket with fine-tuning leveling functionality can be made; the drum can then be placed on this bracket using a crane.
As the owner mentioned, the boiler drum isn’t very large; the fastest way is to lift it up using a crane first, and then construct a simple temporary gantry for alignment. ,
