【Haichuan Expands Horizons】Whole relocation and lifting of a 1,000-cubic-meter liquid ammonia sphere tank

This liquid ammonia sphere tank is 15 meters in height, 12 meters in diameter, weighs 230 tons, and has a volume of 1,000 cubic meters. The Thirteen Construction Machinery Branch, which is responsible for carrying out this lifting operation, uses a Zoomlion 650-ton crawler crane, with a 420-ton counterweight used for lifting. Since this lifting operation takes place within the ammonia tank area in the production zone, a high-risk area, all parties involved attach great importance to it. Before the lifting operation, the project department developed a detailed lifting plan, ensuring proper coordination of various details such as the lifting methods, lifting equipment, foundation treatment, emergency response plans, and safety measures. This approach reduced the risks associated with the lifting process and ensured its smooth execution.

Aren’t large spherical tanks usually welded on-site? Why isn’t this one?

It has already been completed, and due to project requirements, it needs to be moved to a new location. There are two methods: one is to lift and relocate the entire structure, and the other is to cut it apart before reinstalling it

For the overall relocation of the spherical tank, a mesh sling should be used; it should not be lifted from point A of the tank.

The lifting points are directly on the legs; in fact, each leg bears little weight

Do you mean to create a ring-shaped hanging beam?
