Hoisting the heaviest single steel beam in China, Zoomlion crawler crane wins the difficult project

Lifting the equivalent weight of 92 adult elephants，Wearing Aurora green, it can easily do it.。April 20th, 1:00 a.m.，With the help of Zoomlion kiloton Crawler Crane，Completion of Steel Beam Hoisting Construction of Fengcun Bridge across Hanyuan Railway in Shanxi Section of Jidayuan High-speed Railway，Zoomlion Crane Successfully Lifted Weight of 276.4 ton steel beam，Set a record of the heaviest hoisting of a single steel beam in China。

It is understood that，Jidayuan High-speed Railway is a high-speed railway in China.“Eight vertical and eight horizontal”It is an important part of the high-speed railway network in Hunan.。Fengcun Hanyuan Railway Bridge, constructed by the 17th Bureau of China Railway, is located in Huairen City, Shuozhou, Shanxi Province.，Total length 16.2 km，504 spans in total、498 box girder，The hoisting construction of six steel beams needs to cross the important channel of coal transportation in Shanxi Province.——Hanyuan Railway。Hanyuan Railway Passenger Gathering、Freight transportation is integrated，And there are EMU trains running.，There are three trains passing every hour during rush hour.，In addition, the bearing platform of the bridge frame pier is close to the edge of the railway.，The closest distance to the catenary is only 1.2 meters，The alignment accuracy must be controlled within 5 mm.，The construction is extremely difficult、Extremely high security risk，It can be said that“Walk a tightrope on the existing line”。

Due to Hanyuan Railway Passenger、The freight traffic is very busy，Construction can only be carried out from 11:30 p.m. to 1:30 a.m. the next day.，Lock down the construction in these two hours.。The joint expert group of the project side jointly optimizes the hoisting construction scheme of the steel beam，The 1000-ton Crawler Crane of Zoomlion, a subsidiary of Shanxi Hengxin Shuntong Construction Machinery Equipment Leasing Co., Ltd., was selected to undertake the heavy responsibility.。

In the steel beam lifted by Zoomlion crawler crane，Have a length of 33.84 meters，Width 4.58 meters，High 3.5 meters，Weighing 276.4 tons，It needs to be lifted 18 meters above the ground.，Equivalent to the height of a six-storey building，It should also land smoothly on the frame pier.，The deviation should be controlled at millimeter level.，Even the effects of wind must be calculated rigorously.，Do it“Embroidery”Just as fine。The early morning of April 20th，Zoomlion's 1000-ton crawler crane steadily lifts the beam，Rotation、Put it right、Fall、The correction is completed at one go，Construction time is less than 30 minutes.，Win high praise from the project department。

After the Jidayuan High-speed Railway Project is completed and opened to traffic，It will further improve the layout of high-speed railway network in Shanxi Province.，To speed up personnel exchanges along the line.、Promoting regional economic and social development、It is of great significance to promote the development of cultural tourism industry.。Multiple Truck_crane/ 'target='_blank' style='color:blue;'>Truck Cranes of Zoomlion、Crawler cranes are being built at the scene.，Lay a solid foundation for the next step to open the whole line of girder passage。
