On April 28, another success was achieved at the Nantong Blue Sea New Materials project, operated by the fifth branch of Jilin Chemical Construction: the key equipment in the full-density polyethylene extrusion and granulation area, namely the low-pressure separator, was successfully installed in place. It is reported that the low-pressure separator being lifted this time weighs 129.1 tons per unit; it has a diameter of 5.4 meters and a total length of 21 meters, featuring a gourd-shaped structure, and belongs to large-scale custom special equipment. This equipment is large in size and has a complex center of gravity. Moreover, the area designated for extrusion granulation is compactly laid out with numerous structures in the surrounding area, which demands high precision in controlling the lifting path and the positioning accuracy; this makes it a challenging task during construction in this area. In response to the various challenges associated with this project, such as high difficulty in lifting, strict precision requirements, and limited working space, the project team planned ahead and made thorough arrangements, continuously optimizing the specialized lifting plan. The work utilizes a 750-ton crawler crane as the main lifting equipment, with the assistance of a 450-ton truck crane. From lifting the equipment to placing it in position with precision, the entire process took only 2 hours.
