1600 ton crawler crane Guangxi Petrochemical Project full-density polyethylene plant successfully put in place product degassing silo!

On December 27, the hoisting team of CPECC First Construction Company successfully hoisted the important full-density polyethylene device - product degassing silo in the full-density polyethylene plant area of PetroChina Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project. The successful completion of this hoisting marks the perfect end of the hoisting work of large-scale equipment in the installation area, laying a solid foundation for the subsequent construction of the project.

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

The product degassing chamber plays a central role in the production process, efficiently removing gaseous impurities from the product, greatly improving the purity and quality of the product, and making it meet high standards. In addition, it can optimize the production process, improve production efficiency, and reduce production costs.

According to reports, the equipment specifications of the degassing chamber of this product are Φ3700mm/Φ6900mm×51061mm, the weight is 312.4t, and the lifting 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 cooperation. The main crane is selected under SY4-HDB working conditions, and the length of the main boom is up to 144m; The tail lifting crane selects SDB working conditions, the length of the main arm is 84m, and the two work together and cooperate tacitly, and finally realize the successful hoisting of the product degassing silo in place.

Throughout the process, the project team carefully prepared and worked closely together, fully considering various possible problems and formulating detailed and comprehensive response plans. Technicians accurately calculate various parameters, effectively ensuring the safety and stability of the lifting process. The operator uses superb technology to ensure that the product degassing chamber is placed smoothly and precisely.
