Six of the world's best! There is no bridge that Trinity can't build!

Recently，In kiloton cranesSCC15000TM-Precise lifting of 1，World's Largest Span Bridge——Jiangsu Zhangjinggao Yangtze River Bridge Successfully Completed the Hoisting of Steel Box and Reinforcement Cage of South Channel Bridge，It lays a solid foundation for the overall construction of the diaphragm wall in the next step.。

6 items“The best in the world”

Zhangjinggao Yangtze River Bridge is located in the core area of the Yangtze River Delta.，Connect to Suzhou、Taizhou and Nantong，The total length of the cross-river section is 7859 meters.，It's the country“Fourteen five”Key projects，Yeah, too“China Bridge”The opening work of breaking through the 2000-meter span barrier for the first time。

The bridge created multiple“The best in the world”。Its South Channel Bridge is a super-large span suspension bridge with a main span of 2300 meters.，It is the world's largest span bridge.。The south main tower of South Channel Bridge is 350 meters high.，Tower of the world's highest suspension bridge。

TrinitySCC15000TM-1. The south anchorage of the bridge participated in the construction，Adopt the world's first composite diaphragm wall foundation with supporting and rotating structures，After completion, it will be the anchorage foundation of the world's largest diaphragm wall.。

In addition，The bridge also created the world's longest high-strength main cable.、World's largest continuous length of steel box girder、Telescopic device with lar displacement in that world6 items in total“The best in the world”。

“No drop in the chain at all.”

The south anchorage diaphragm wall of this construction is divided into 94 Phase I trench sections and 104 Phase II trench sections.，By TrinitySCC15000TM-1. Undertake the hoisting task of core steel box and reinforcement cage。

Mr. Zhu, the project manager of CCCC Second Harbor Engineering Co., Ltd., said.：“Large amount of welding for steel box manufacturing、Transport segment length，The structure is easy to collide、Hoisting is easy to deform，The hoisting equipment of the headquarters shall be strictly controlled.，Yes, transshipment、Loading、Unload、Precise measurement of lifting lug placement and other links，Make every effort to ensure the lifting operation of the diaphragm wall steel box。”

“A single steel box weighs up to 370 tons.，The equipment should not only be lifted.、Hang far，And very steady，Avoid shaking and deformation during lifting。”Operator Wang Feige introduced，SCC15000TM-1. This construction adopts 60m super-wide arm working condition.，Belt 500tHook，Span 16m，Make sure nothing goes wrong。

Wang Feige said，In the process of hoisting hundreds of steel boxes，TrinitySCC15000TM-1 Play stably，“No drop in the chain at all.”，“The successful completion of this project node，It has also accumulated a lot of experience for the hoisting of the steel box of the north anchorage diaphragm wall.”。

The Zhangjinggao Yangtze River Bridge is scheduled to open to traffic in June 2028.，After completion, it will be closer to Suzhou.、Nantong、Space-time distance of three cities in Taizhou，Promoting regional integration in the Yangtze River Delta。
