The 1600-ton crawler crane Guangxi Petrochemical Project full-density polyethylene plant was successfully put in place for the product degassing chamber!

On December 27, the hoisting team of CPECC No. 1 Construction Company successfully hoisted the product degassing chamber, an important device of full-density polyethylene, in the full-density polyethylene plant area of PetroChina Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project. The successful completion of the hoisting marks the perfect conclusion of the large-scale equipment hoisting work in the installation area, and lays a solid foundation for the subsequent construction of the project.

It is understood that the hoisting operation is facing many challenges. There are many construction units on site, limited space, and difficult vehicle transfers, especially unfavorable conditions such as vehicle assembly and narrow lifting sites, which add significant difficulties to the hoisting.

Product degassing chambers play a central role in the production process, efficiently removing gaseous impurities from the product, significantly improving the purity and quality of the product to meet high standards. In addition, it is possible to optimize production processes, improve production efficiency, and reduce production costs.

According to reports, the equipment specifications of the degassing chamber of the product are Φ3700mm/Φ6900mm×51061mm, the weight is 312.4t, and the hoisting height is 111311mm. In order to achieve this arduous task, the "single host lifting and delivery" method was adopted on site, and one was activatedTrinity SCC19800TMType 1600t trackcraneAs the main force of the main crane, an LR1400-2 400t crawler crane is responsible for tail lifting and coordination. The main crane is made of SY4-HDB working conditions, and the length of the main boom is up to 144m; The tail lifting and matching crane is selected under SDB working conditions and the length of the main boom is 84m, and the two work together and cooperate tacitly, and finally realize the successful hoisting of the product degassing chamber in place.

Throughout the process, the project team carefully prepared and worked closely together, fully considering all kinds of possible problems and formulating detailed and comprehensive response plans. The technicians accurately calculate the parameters to effectively ensure the safety and stability of the hoisting process. With superb technology, the operator makes the product degassing chamber complete smoothly and accurately in place.
