The hoisting of Zoomlion crane“ Jigsaw puzzle ”Yes“Linglong No.1”Steel containment top head，It belongs to the steel containment of nuclear island plant.。“Linglong No.1”Steel containment shaped like an upright capsule，Contain the internal structure of the reactor building，Like a guarantee“The heart of Ling Long”Safe“Golden Bell Jar”，It plays a key role in ensuring the integrity and tightness of the reactor building.。

“Linglong No.1”The steel containment top head weighs about 280 tons，The total weight within the lifting load range is about 390 tons.。Its positioning means that the most difficult installation of the nuclear island's steel containment vessel has been completed.，Reactor building“ Capsule ”A protective structure has been formed.。Hoisting，Zoomlion Crane Shows Precision、Efficient、Stable heavy equipment strength。Before，“Linglong No.1”Reactor core module“The heart of Ling Long”，It is also hoisted in place by Zoomlion crane.。
