On March 23, at the construction site of the catalytic cracking (RTC) unit in the Maoming Petrochemical upgrading project, which is being carried out by Sinopec Fourth Construction Company’s South China branch, the lifting of three spin-type end caps and two major components belonging to the third section of the reaction settler was successfully completed in a single day, providing strong momentum for the construction of this unit. Faced with the severe challenges of lifting heavy equipment such as the three-spin head (approximately 285 tons, diameter 18 meters) and the third section of the reaction settler (260 tons, diameter 11 meters), strict safety requirements were implemented and the work processes were optimized; through high-standard construction practices, both pieces of equipment were accurately installed within a single day. The successful installation of both cranes on the same day demonstrates fully the spirit of determination, hard work, and responsibility shown by all Party members involved in the construction.

The difficult part isn’t lifting the heavy components; it’s the initial phase of getting the large crawler cranes in place for assembly, as well as the need to turn the tank heads 180° after lining them.
