The selection of on-site sling operation and lifting method should be combined with actual conditions

Petrochemical large equipment lifting is an important construction procedure in the petrochemical industry. According to the parameters of the volume and quality of the equipment to be hoisted, the hoisting items are divided into tower, container, slender, thin shell and other types, and the characteristics of each type of equipment and its requirements for hoisting operations are summarized. Split lifting and integral lifting are the two main branches of lifting technology.

The split hoisting technology has low requirements for space and lifting equipment. It can divide large equipment into multiple parts for hoisting to complete the lifting task, but the split hoisting design and construction are complicated, requiring relevant personnel with high professional quality; overall hoisting Compared with split hoisting, the overall operation of hoisting articles has high construction efficiency and relatively simple operation. However, the overall hoisting technology requires higher lifting equipment and working space, which requires large lifting equipment and sufficient vertical and Horizontal working space.

In the field construction, the lifting equipment such as lifting ears and cranes should be reasonably selected according to the type of lifting items and the characteristics of the slings and lifting equipment. The two hoisting technologies should learn from each other and complement each other's advantages. Under the premise of ensuring safe and smooth production, the maximum economic benefits can be obtained with the minimum investment.
