CCTV documentary《Great power construction》Tell the story of Chinese engineering with high quality development in the new era。The project reported in the first issue of the second quarter is Zoomlion.ZCC5000-Xiamen New Convention and Exhibition Center Constructed by Crawler Crane。

Xiamen，The city is on the sea，The sea is in the city。The steel structure forms a swallow-tailed ridge.，It means a wanderer in the distance.，Always come back in the spring.。Xiamen New Convention and Exhibition Center covering an area of nearly 820000 square meters，More than 180,000 tons of steel structure，Steel frame in the center+Space pipe truss structure form，Maximum truss span 81 m。Vertically and horizontally formed super-large houses in southern Fujian，In the expectation of a thousand years，Top the next hundred years。

The most difficult link in the construction is the super-large steel structure of the roof.“Swallowtail Ridge”The overall capping。The site soil is soft，Difficult to find a suitable lifting point。In response to this situation，The construction team developed a groundbreaking“Lift first、Re-weld、And finally slide in place”Construction plan。

As the most important part of the overall construction，The lifting of steel structure coincided with the landing of typhoon，Amid intense typhoon warnings and heavy rain，The dovetail steel frame should complete the air landing before the typhoon lands.。It's a race against time.。Quanzhou Hongyuan Construction Machinery Leasing Co., Ltd.ZCC5000-1 Crawler crane。

ZoomlionZCC5000-1 Rated lifting 500T，The maximum lifting moment is 6320tm。Powerful performance becomes the basis for undertaking this important task.，But more importantly,ZCC5000-1 Fretting performance and stability superior to peers。This is for this hoisting task, which requires extremely high accuracy.，It is the greatest guarantee.。ZoomlionZCC5000-1. Precise and stable hoisting，The super-large dovetail steel frame of nearly 200 tons was lifted to the roof.。After completion of hoisting and welding，After 2 hours of sliding，The dovetail steel frame flew through the wind and rain for 60 meters and landed perfectly.。
