Frequency conversion control synchronous lifting hydraulic system is used in the expansion lifting project of Huai’an section of Beijing-Shanghai Expressway

The expansion lifting project of the Huai'an section of the Beijing-Shanghai Expressway uses the Kaient variable frequency control synchronous lifting hydraulic system to jack up 16 hydraulic jacks synchronously. The Huai'an section of the Beijing-Shanghai Expressway has a total length of 106.939 kilometers. The whole line adopts the standard reconstruction and expansion of a two-way eight-lane expressway. The design speed is 120 kilometers per hour. There are 96 bridges and 8 interchanges on the whole line. The construction of the Huai'an section of the Beijing-Shanghai Expressway Reconstruction and Expansion Project is of great significance for further accelerating the construction of an important central city in Huai'an North Jiangsu, driving the development of the eastern urban area of ​​Huai'an, revitalizing the North Jiangsu economy, and strengthening foreign exchanges in North Jiangsu.
