【Haichuan Heavy-Lift Installation Case】001—500-ton Module on Top of Huizhou Petrochemical Gasification Frame
Thread Content
Recently, the module lifting at the construction site of the Huizhou petrochemical project got off to a strong start. The first module at the lifting site – Module 1 – was slowly raised; once it reached a height of over 35 meters above the top of the gasification frame, the module had completed a 90-degree rotation and was now hovering there. Thereafter, alignment, temporary reinforcement, and welding were carried out, and the module lifting was completed successfully.
Module 1 utilizes a deep prefabrication process; it is the heaviest, largest in volume, and deepest in prefabrication level module that the project team has ever constructed to date through on-site assembly followed by lifting. It consists of a two-story steel structure with 16 columns, having a total height of 12.0 m, a length of 33.0 m, and a width of 25.5 m, with a weight of 514.5 tons. On its two floors there are installed certain pipes and small equipment that have been completed. It is lifted to the 35.0-m-high frame for installation by a 1600-ton crawler crane standing tall on the north side of the vaporization frame. Module 1 has a total of 12 lifting points, which are arranged symmetrically in two areas at the top of the module; these points are connected via 12 sets of steel cables to the balance beam.
Could someone share the advantages of modular installation? ! !
The advantage is that the modules can be assembled on the ground, reducing the risks associated with working at heights and speeding up the process; the disadvantage is that it increases the risks related to large-scale lifting operations.
Thanks for clearing up the doubt! :For the handshake, non-module installation tasks that involve working at heights should also take place at the “heights” within the platform’s interior area, right?
