Finish the last piece of the puzzle! Zoomlion Crane Successfully Hoisted the Outer Dome of "Linglong No.1"

Recently，The world's first onshore commercial small modular nuclear reactor“Linglong No.1”The outer dome was successfully hoisted by a 3,200-ton Crawler Crane of Zoomlion in Changjiang, Hainan， Success “Finish spelling”The final piece of the reactor building puzzle。This marks“Linglong No.1”The reactor building is in a state of full closeout，It laid the foundation for the subsequent capping of the reactor building.。

The total hoisting weight of the outer dome is about 550 tons.，Yes, at present“Linglong No.1”The item with the largest lifting capacity in the small reactor science and technology demonstration project。The construction of the outer dome also pioneered the construction method of integral hoisting of steel roof and steel bars.，Assemble the dome on the ground and bind the steel bars on the dome.，Then, the 3200-ton Crawler Crane of Zoomlion is used for integral hoisting.。This reduces the workload and operation difficulty of high-altitude steel bar transportation.，The construction period of the site is saved.。

The scene of the day，As the wind speed measurement meets the standard，Zoomlion's 3,200-ton crawler crane slowly lifted the outer dome off the ground.，Through luffing、Lifting Hook、Walk and translate、A series of actions such as adjustment，Put the hook in place stably on the outer containment shell of the reactor building.，Lasting 1 hour and 38 minutes。The successful hoisting successfully verified the nuclear island.“Steel roof+Rebar”Feasibility of integral module hoisting，It also provides experience for the subsequent modular development of nuclear power.。

In recent years，Nuclear Power Construction in China，In particular“Hualong One”And“Linglong No.1”In the process of construction，Zoomlion's crane equipment gives full play to its performance and technical advantages，Successfully completed many major hoisting tasks of nuclear power construction，It has made great contributions and responsibilities for China's nuclear power construction.。Future，Zoomlion will continue to give full play to its strength in technology research and development and product manufacturing.，To provide equipment guarantee for the construction of major projects in China。
