77 seconds｜China largest single-lifting crawler crane successfully completed the task of lifting the passenger overpass of Weifang Railway Station

At about 11:30 pm on 10th,Sep,2020, the heaviest and longest section of the steel truss structure of the new passenger flyover project at Weifang Railway Station was successfully hoisted and connected. The entire project was hoisted by a 2000-ton crawler crane 5 times within 5 days. The hoisting span is the longest in the country on existing railway lines.

At the construction site of the new passenger flyover project at Weifang Railway Station, a 2000-ton crawler crane developed by my country is steadily hoisting a steel truss structure to a predetermined position and completing the rotating connection.

According to Du Yun, the project manager of the new passenger flyover project at the Weifang Station of the China Railway Erju Group Shenzhen Company, this is the fourth and penultimate section of hoisting. The length is 40.25 meters and the weight is more than 220 tons. During the entire 5 hoisting process , This paragraph is the longest and the heaviest.

It is understood that the passenger flyover of Weifang Railway Station mainly connects the existing North Station Building and the newly built South Station Building. It is 135.5 meters long, 12 meters wide, 6.59 meters high, and weighs about 650 tons. It spans Weifang Railway Station. 12 lanes on 4 platforms. As the passenger flyover is built on the existing line, the construction can only be carried out by using the "window period" when the night train is out of service. The lifting time is very tight, and the construction accuracy requirements are also very high. After repeated demonstrations, the project department finally decided to use the 2000-ton crawler crane, The crane completed the steel truss structure hoisting task five times within five days. This is also the first time that a large-tonnage crane of 2,000 tons and above is used in the construction of a railway station in China.

Mr. Zeng Hongquan, deputy general manager of the Shenzhen Branch of China Railway Erju Group, told reporters that after the technical team combined with the actual situation on the site and various technical parameters, it was finally decided to use the more advanced 2,000-ton crawler crane in the country to ensure that the specified tasks were completed within the specified time. , The engineering construction did not cause any interference to the trains entering and leaving the Weifang Station, while ensuring the accuracy of the project, which can be fully completed within the prescribed 90 minutes.

It is reported that on the evening of 11th, Sep, the last steel truss structure of the new passenger flyover project at Weifang Railway Station was also hoisted and connected, and the main part of the project was completed. The completion of the project will promote the transformation of the railway hub industry characterized by second-class industries and logistics services. The upgrade and the rise of new urban areas have opened a new page for the construction of the entire Zhannan Square area in Weifang.
