The moat becomes a thoroughfare! Look at the Sany tower crane on the Yellow River hardcore bridge

With the first rays of sunshine in the morning, service engineer Yu Jinlong quickly climbed the nearly 40-meter-high tower crane along the steel ladder on the side of the bridge pier and started the busy inspection work again.

Through the steel mesh window, he looked at the Sany tower cranes, like soldiers going to the battlefield, lined up in a neat line, across the banks of the Yellow River, mighty and majestic. The password of the "hanging basket cantilever pouring" construction of the box girder kept coming to his ears, and his heart was full of excitement and pride.

Here is the Xinxiang Kaifeng Yellow River Bridge and connecting line project, is the "National Highway Network Planning" in the 230 National Highway across the Yellow River throat project, but also Henan Province 11 vertical and 11 horizontal highway main skeleton in a vertical and important part. The total investment of the project is 4.9 billion yuan, and the total length of the bridge is 24.196 kilometers, which is designed in accordance with the standard of two-way six-lane first-class highway.

At the construction site, thousands of construction personnel stuck to their posts, sweated like rain, and worked hard to promote the construction of the project. Yu Jinlong introduced: "Since March this year, after the pier of the main bridge across the river came out of the water, the project has successively entered the site with 14 Sany SFT125 (T6016-8C5) flat-top tower cranes, which play an obvious role in the construction of the pile foundation of the approach bridge in the embankment, the lifting of steel box girders across the embankment, and the thin-walled piers of the main bridge. ”

Xu Xiangguang of Hebei Yanhuan Construction Machinery Co., Ltd. is responsible for the management of the on-site tower crane, he introduced: "The construction, SFT125 (T6016-8C5) flat-top tower crane has a maximum lifting weight of 7.5 tons and a slewing radius of not less than 50 meters, which well meets the construction needs and effectively solves the problems of narrow construction sites across the river and inconvenient material transportation. ”

"It is convenient and fast, safe and stable in operation, and has a series of intelligent technologies such as calibration-free, anti-collision, and intelligent control, which has pressed the accelerator button for construction. At present, the project has realized the erection of a single width of the bridge across the embankment and the approach bridge plate outside the embankment, and is about to enter a new stage of bridge deck series construction. Next month, we will erect 3 more Sany tower cranes, and the main bridge construction section will be increased to 17 units, and at that time, a new construction climax may be set off again. For Sany tower crane, Xu Xiangguang is full of confidence.

In June, the sun was scorching and the machinery roared, and the Xinxiang Kaifeng Yellow River Bridge and connecting line project was one step closer to completion. After it is completed and opened to traffic, it will open up the national highway and open up the national transportation channel, improve the transportation conditions of the masses on both sides of the Yellow River, and at the same time, it is of great significance to strengthen the inter-city connection in the Zhengzhou metropolitan area and accelerate the construction of the Central Plains urban agglomeration.
