Zoomlion Crawler Crane Helps Hualong 1 Successfully Hoist the World's First Three-Layer Ring Section Combined Steel Lining Module
November 16, 2022
Recently，The third steel lining module of Hainan Changjiang Nuclear Power Unit 4, which was jointly constructed by China Nuclear Power 22 and China Nuclear Machinery Engineering, was successfully hoisted.，This is the first successful hoisting of the three-layer ring section combined steel lining module of Hualong 1 in the world.。It was Zoomlion that undertook the hoisting task.ZCC32000 Crawler Crane。

The steel lining module III hoisted this time is assembled by three layers of cylinder walls.，Inner diameter 46.8 meters，Overall height 14.94 meters，Total weight about 176 tons，Three-layer steel lining cylinder wall is creatively adopted.（4 sections of cylinder wall、Paragraph 5、6 paragraphs）Assemble at one time、Hoisting，It is the first time in the world that it has been applied and implemented in Hualong 1 reactor.，It breaks through the traditional sectional mode of two-layer cylinder wall steel lining.，It directly spans the construction period of one layer of steel lining.，Reduces high-altitude hoisting、Welding and other workload，The safety and quality level of steel lining construction has been greatly improved.。

In the early morning of November 5th，Night is falling，The construction site of Hainan Changjiang Nuclear Power Plant is brightly lit.，All personnel on site、The equipment is ready。After the last check.，The site commander in chief ordered to start hoisting.。ZCCThe 32000 starts slowly，The huge steel-lined module slowly leaves the ground as the crane boom rises.。After lifting、Luffing、Walk、In the middle、Descend，Realize precise docking with module 2，This marks that the construction of the inner shell of the reactor building of Unit 4 has entered more layers of continuous construction.，To organize construction more efficiently、And favorable condition are created for bet guaranteeing that construction quality of the cylinder concrete.。
