Recently，Nanchang South Railway Station Steel Truss Overpass Successfully Hoisted in Place，Nanchang South Railway Station(Henggang station）The completion of the reconstruction on schedule laid a solid foundation.，The 650-ton crawler crane of Zoomlion completed the hoisting task.。

Four in the morning，Night is falling，It's time for a good dream.，Nanchang South Railway Station（Henggang station）Lights were blazing outside，Zoomlion cranes and on-site construction personnel are standing by.。With“In position”Give the order，It lasted two hours.，The 650-ton crawler crane of Zoomlion successfully placed the 106-ton steel truss overpass over four railway operating lines.。

The overall hoisting operation of the overpass needs to use the skylight point construction on the existing high-speed railway line.，The length of the overpass from platform 2 to platform 3 is 29.3 meters、It weighs 106 tons，Short time、The precision is high，It is difficult to coordinate the lifting of super-large components across the existing railway。To ensure the construction safety management requirements，The participating units of the project organized experts to study and demonstrate the construction scheme of overpass hoisting for many times.，Use professional software to simulate the lifting process.，Organize trial lifting operation，Continuously optimize the scheme，Finally, the construction method of on-site assembly and integral hoisting is adopted.。

During construction operation，The 650-ton crawler crane of Zoomlion first lifted the overpass to 14.7 meters，The crane rotates 149 degrees to the upper part of the overpass support.，Adjust the direction and position of the overpass through the traction rope，Fall slowly，Achieve precise alignment by using overpass limit plate，Smooth lowering, welding and fixing。The whole hoisting seems easy.，In fact, it is quite difficult.。This is because the overall hoisting of the steel truss overpass is risky.、Difficult control project；Hoisting at night，It also increases the difficulty of homework.。However, the 650-ton crawler crane of Zoomlion has always maintained high accuracy and stability.，It has won the unanimous praise of the engineering side.。

It is understood that，Nanchang South Railway Station(Henggang station）It is an important passenger station on the Beijing-Hong Kong high-speed railway and the Beijing-Kowloon railway.，Have“South Gate of Nanchang”Known as，The hoisting of the overpass was completed.，To ensure the formation of Nanchang South Railway Station by the end of the year(Henggang station）New station shape，To meet the needs of Spring Festival Transport。Newly reconstructed Nanchang South Railway Station(Henggang station），It will become a new window for Nanchang to open to the outside world.，It is connected with the Shanghai-Kunming high-speed railway through the connecting line.，Constitute the development of Nanchang、Modern、Complete transportation network，Accelerating the Economic Integration of the Yangtze River，Promote the rapid development of local economy。
