On August 23, 2022, CNNC successfully completed the hoisting of the inner dome of Zhangzhou Nuclear Power Unit 2. This dome was successfully hoisted ahead of schedule, setting the shortest construction period for the hoisting of a single unit of Hualong 1 from the FCD to the inner dome under the premise of the implementation of the open-roof method. new record. The hoisting was completed by Zoomlion ZCC3200NP 3200-ton crawler crane.

The dome of Unit 2 is large in size and heavy in weight. When it is in place, it needs to accurately fall into the guide groove with a width of only 10mm at the narrowest part of the top of the nuclear island, which requires high hoisting accuracy and hoisting stability of the crane. The hoisting was officially lifted at 6:80 and was in place at 9:28, with a total duration of 3:20. The inner dome of Unit 2 is a ribbed hemispherical shell with an outer diameter of 46.8 meters, a height of 23.4 meters, and a total hoisting weight of about 522 tons. In the face of such a challenging hoisting operation, Zoomlion ZCC3200NP seems to be able to handle the hoisting work successfully.

In October 2021, ZCC3200NP successfully completed the hoisting of the dome of Zhangzhou Nuclear Power Hualong No. 1 Unit 1. In the hoisting of several projects, China Nuclear Machinery has used Zoomlion ZCC3200NP crawler cranes for operation, which is highly recognized by customers for Zoomlion's products.

Compared with the dome hoisting of Unit 1, this operation has a larger hoisting radius. In order to improve the hoisting safety, the connection method of the slings has been improved, and the hoisting safety distance has been lengthened. Before hoisting, CNNC repeatedly checked the crane assembly and test, rigging, dome simulated trial hoisting and trial hoisting adjustment and other preparations to ensure that the hoisting was foolproof.

With its super high hoisting performance, ZCC3200NP has successfully completed the hoisting tasks of Hualong No. 1 unit dome and steel lining modules in Fuqing, Zhangzhou, Changjiang and other places, and is known as the best partner for nuclear power construction. In the future, this great power weapon, which has repeatedly made extraordinary achievements in my country's energy construction, will continue to shoulder the heavy responsibility of building a strong country.Editor/Zhao E
