On the morning of February 17th，Zhangzhou Nuclear Power Station in Fujian，The 3200-ton crane of Zoomlion has been successfully hoisted.“Hualong One”Outer dome of the first unit in the batch construction phase，This marks the completion of the main structure of the unit.，Lay a solid foundation for subsequent grid-connected power generation。CCTV Live News Focus，CCTV News Channel《Live news room》The column focuses on reporting。

6:38 a.m，As the wind speed measurement meets the standard，Zoomlion's 3,200-ton crane slowly lifted the outer dome, which weighs about 420 tons, off the ground.，Through luffing、Lifting Hook、Walk and translate、A series of high-precision actions such as adjustment，Put the hook in place stably on the outer containment shell of the reactor building.，The hoisting was successfully completed at 9:30.。This is“Hualong One”Hoisting of the outer dome of the first nuclear power unit after mass construction。

The steel lining of the outer dome to be lifted this time is the main steel structure.，Located at the top of the nuclear island，It's about 55 meters in diameter.、Multi-curved composite shell with a height of about 13 meters，It is composed of 89 prefabricated unit components in five layers.，Its main function is to act as a concrete formwork on the top of the outer dome.。Lifting of the outer dome requires a one-time success.，And the deformation within 1 meter shall not exceed 1 mm.，In the face of such high precision、Difficult lifting task，Zoomlion 3,200-ton crane still efficient、Precise、Stable、The construction was completed safely.，To ensure the smooth progress of follow-up work.。

On the air，Wu Min, General Manager of Zhangzhou Nuclear Power Project Department of China Nuclear Industry 24 Construction Co., Ltd., sighed.：“China's manufacturing industry has also undergone rapid changes in the past decade.，In the past, foreign technology and cranes may have been used to hang the dome.，But in the past ten years, the domestic equipment manufacturing has been ahead of the world.。”Development in the past ten years，So that our country has 3200 tons of crane such independent research and development of lifting equipment.，It can be efficient、High standards、Safe、Stable、Easily carry out dome hoisting construction。

It is understood that，“Hualong One”It is the only three-generation nuclear power first reactor project completed and put into operation on schedule in the world.，The first four units were completed and put into operation.，It marks that China's nuclear power technology level has ranked in the forefront of the world.。At“Hualong One”During the construction of the project，Zoomlion has successfully completed the hoisting task of 3200 tons for many times，It is called nuclear power construction.“Best partner”。
