Soar to the top，The Yellow River is surging

Above the natural moat，An arch flies across

Recently，At the project site of the Yellow River Bridge on Gaoshang Expressway，The main arch of the 3425-meter-long Yellow River Bridge is like a beautiful rainbow.，Winding over the rolling waves of the Yellow River，And three XCMG super cranesXCA500 standing on the bridge，It is particularly noticeable。

The Yellow River Bridge isThe largest through concrete-filled steel tubular tied arch bridge in China at present，As a set upMain arch ring of arch bridge“Skeleton”——Arch RibThe main force，How is the XCMG crane erected?“Rainbow”What about？

General Manager Li, who is in charge of on-site hoisting, gave the answer.：

“The hoisting scheme is the first 500-ton crane bridge project in China.。Before hoisting，It is necessary to hoist the basket in place first.，The arch ribs are then hoisted to the deck.，Welding of butt bolts，Finally, adjust the arch。”

“The maximum arch length of the bridge is 9 meters.，5 meters high，Width 2.8 meters，It weighs 53 tons，Up to 65 meters。This is for the crane.Stability、HandlingThe requirements are very high，XCMG 500 tons performed very well。Because it is a cross-Yellow River operation.，There is no shelter around，There is a lot of wind resistance，Lifting through the aperture，Transportation of arch ribs to the deck，Air docking is carried out with the tacit cooperation of workers.。”

It is reported that，The arch rib has to be hoisted and spliced more than 200 times.，In order to form a complete arch on the bridge.，These three XCMG super cranesXCA500 will be stationed in the project for one year。

After the completion of the project，The Yellow River Bridge will becomeThe Largest Through CFST Tied Arch Bridge in China，To improve regional traffic conditions，It is of great significance to promote the high-quality development of the Yellow River Basin.。
