January 11，The first hook of Hainan Changjiang Nuclear Power Unit 3 in the first year——Ring beam and ring rail hoisting，In ZoomlionZCC3200NPPrecise positioning under stable hoisting of crawler crane，Take the New Year“A good start”，It is also ready for the No.3 nuclear island to enter the capping stage.。

The total assembly weight of ring beam and ring rail is about 150 tons.，Wherein the ring beam is of a box-shaped structures，It is divided into 9 sections.，Total 15 sections at the beginning of ring rail，Finally, it is welded into 5 sections and hoisted to the upper part of the ring beam and fixed with a pressure plate.，And the ring beam and ring rail assembly of Unit 3 adopts“Ground assembled into a ring、Hoisting in place at one time”Installation method，Very high requirements for installation accuracy。

The volume of the hoisting equipment is huge.、The weight is heavy、The operation site is limited，To ensure the safety of hoisting、Reliability and lifting efficiency，The project side selected the 3200-ton crawler crane of Zoomlion, which has made outstanding achievements in the field of nuclear power hoisting.，And the optimal route is designed through refinement.、The best station location、Minimum hours，Always keep the load factor at 57.6％Following。Hoisting lasts about 3 hours.，After trial lifting、Promote、Luffing、Rotate counterclockwise、Precise positioning after a series of actions such as walking with load，The whole construction process is smooth.、Safe、Fluent、The quality is controllable。

 

It is understood that，In order to ensure the safe and smooth hoisting in place of the first crane of the ring bearing beam and ring rail,，Huaneng Hainan Changjiang Nuclear Power Co., Ltd. joins hands with all participating units，Carefully organized、Scientific planning，Optimize the overall construction logic，Analyze and eliminate constraints in advance，Overcome all kinds of difficulties and challenges in the process of installation and hoisting，It lays a solid foundation for the successful realization of ring crane girder hoisting and subsequent dome hoisting nodes.。

 

According to introduction，ZoomlionZCC3200NPCrawler crane is not only the first 3000-ton super-large tonnage crawler crane in China.，Yeah, tooAt present, the only simultaneous application in the world is in the second、Three、3000-ton crawler crane for fourth-generation nuclear power hoisting，It is specially developed to ensure the safety of nuclear power construction in China.。Its maximum lifting capacity is 3200 tons.，The maximum lifting moment reaches t/m 82000.，It is one of the crawler cranes with the best lifting capacity and technical level in the world.。

Since going offline，ZCC3200NPTianwan Nuclear Power Station in Jiangsu、Shandong Shidaowan Nuclear Power Station、“Linglong No.1”On large-scale nuclear power construction projects in many countries.“Show off your skills”，And three times as“Hualong One”Success“Crowned”，It is called nuclear power construction.“Best partner”。
