ZAT6000H "Building Blocks" in the Air, Completing 113 Tons of Steel Box Girder Hoisting Construction

In the early morning of October 12th，Dalian Guiyuan Hoisting and Installation Engineering Co., Ltd. and ZoomlionZAT6000HAll Terrain Crane，Successfully completed Guangming Road Extension Project 201 National Highway Interchange across Metro Line 3（Pier 36——Pier 35）Hoisting task of 10 sections of steel box girders on the north and south sides。

National Highway 201 Interchange is an extension project of Guangming Road.“Four bridges and one tunnel”An important part of，The main line of the bridge is about 1 km long.，Continuous overpass of Shenyang-Dalian Railway Line、Zhenxing Road、Metro Line 3 and National Highway 201。The 201 National Highway Interchange hoisted this time crosses Metro Line 3（Number 35——Span 36）The total weight of the steel box girder is about 458 tons.，The maximum weight of a single section is 113 tons.，It is the heaviest steel box girder section of the whole line.。

00 on the 12th，Subway Closed Window Arrives as Scheduled，Start hoisting of steel box girder。Zoomlion is used for bridge hoisting.ZAT6000HAll-terrain crane as main lifting equipment，Multiple lift Trucks、Coordinated operation of Vehicle/ 'target='_blank' style='color:blue;'>Transport Vehicles。Because it will be constructed across the existing Metro Line 3.，Therefore, the construction period can only be chosen in the early morning.。The hoisting weight is large、It is difficult to transport、High requirements for safety protection of the light rail below、High requirement for docking accuracy，It has become the key and difficult point of this steel box girder hoisting.。

Crane on，Several workers stood at the top of the beam section to bind the wire rope.，Check the hook、Hanging rope, etc，And then，The crane slowly lifts the steel box girder to high altitude.，Finally fixed on the beam。The person in charge of the project shall lead the shift on site.，Safe、Technicians watch the whole process，Standard control of construction personnel，Co-management personnel organize traffic guidance and safety warnings，The whole hoisting process is safe.、Orderly、Controllable。After three nights and more than 14 hours of intensive night work,，The last steel box girder across Metro Line 3 is stable.、Precise placement，It marks the crossing of Metro Line 3 on National Highway 201.（Pier 35——Pier 36）Completion of hoisting of all steel box girders，Guangming Road Overpass Steel Box Girder Hoisting Has Completed Another Important Node。

This hoisting operation，Although it is quite challenging in terms of construction difficulty and accuracy requirements.，But for Dalian Guiyuan Hoisting and ZoomlionZAT6000HThe all-terrain crane is already familiar with it.。As early as July 24.，The 201 National Highway Interchange has been completed across the existing line.（Pier 58-Pier 59）Hoisting of steel box girder。Hoisting this timeZAT6000HAll-terrain crane still performs well、Play steadily，It shows the excellent lifting performance of Zoomlion crane and the accuracy of high-altitude hoisting.。

The successful completion of this hoisting，The construction of the main structure of the 201 National Highway Interchange was accelerated.。It ensures that the hoisting task of steel box girder of Guangming Road Extension Project across Zhenxing Road can be completed on schedule with high quality.，Help Dalian's urban construction。
