On the morning of October 23, the opening ceremony of the Hong Kong-Zhuhai-Macao Bridge was held in Zhuhai, Guangdong. This historic moment is very encouraging.


The Hong Kong-Zhuhai-Macao Bridge, which is known as the world's longest cross-sea bridge, was officially opened. The Zhongshan people are proud that more than 70% of the bridges are built by Zhongshan. The information provided by the Zhongshan Maritime Safety Administration, which is responsible for the escort of the large-scale components of the bridge, shows that the project involves nearly 800 voyages of large-scale component water transport operations, of which 615 voyages were shipped from the Zhongshan base, accounting for more than 70%.


Imported steel, manufactured in Zhongshan and installed in Hong Kong, is a typical feature of the construction of the Hong Kong-Zhuhai-Macao Bridge. The site of the China Second Navigation Bureau, located in Linhai Industrial Park, Cuiheng New District, Zhongshan City, was the busiest during the construction of the Hong Kong-Zhuhai-Macao Bridge. The bridge from the Guangdong-Hong Kong boundary line in the Yan yang to the Hong Kong airport is known as the Hong Kong-Zhuhai-Macao Bridge "Hong Kong Wiring Viaduct Project" proposal, which was built by the famous bridge builder, the China Second Navigation Bureau.


Zhongshan is the largest prefabricated component production base in the Pearl River Delta region. All steel box girder of Hong Kong-Zhuhai-Macao Bridge Hong Kong wiring viaduct project is produced here, using advanced overall manufacturing and hoisting construction technology to minimize the risk of offshore construction.


Before the bridge was completed, the hoisting of three Dolphin steel towers was one of the key points and difficulties in the construction of the bridge. After the hoisting of the first two Dolphin Towers, the hoisting of the third Dolphin Tower has been plagued by the Hong Kong-Zhuhai-Macao Bridge Bureau. This means that the Dolphin Tower will have to turn over 180 degrees. The Dolphin Tower weighs 2,560 tons, equivalent to 11 empty A380 aircraft, with a height of 105 meters, which is equivalent to 35 stories. There is no precedent for the large-scale steel tower of this size to turn around in the world.


In the end, this task fell to the China Railway South Engineering Equipment Co., Ltd. in the Cuiheng New District. The "Hercules" that implemented the turn-around was the company's two 2000-ton gantry cranes, which is currently the world's largest lifting crane. Mobile gantry crane. The turn-around of the Dolphin Tower in Zhongshan was called "the world's first turn".
