Zoomlion has set a new record! QUY650 and ZCC5200S completed the hoisting of the heaviest steel casting of cable-stayed bridge in China!

June 6, 2023，It is contracted by Sinohydro Bureau 7 Co., Ltd.、Hoisting in place of large steel castings of Chengdu Bridge across Jiangxi River undertaken by China Railway Heavy Industry Southwest Branch，Set a record for hoisting steel castings of the heaviest multi-directional cable-stayed bridge in China！This hoisting is carried out by Sichuan Xinlu Equipment Hoisting Engineering Co., Ltd.QUY650、ZCC5200SDone together。

The North First Line Bridge across Jiangxi River is located in Chengdu High-tech Aviation Economic Zone.，By GermanysbpSchleich Engineering Design Consulting Co., Ltd.。The span of the bridge is 147 meters.，It is a five-span single-side cable-stayed bridge.，Longitudinal and transverse beam structure system is adopted for the bridge deck.，The pylon and girder consolidation section and the bridge pylon are curved structures with nine deformed sections.，Back cable adopts 350tTon castings，The requirements for installation accuracy and welding quality are very high。

This hoisting is the most important 350 of this project.tTon castings，Sichuan Xinlu Equipment Hoisting Engineering Co., Ltd.QUY650、ZCC5200SDone together。

To ensure the successful completion of box girder erection，The project department is fully deployed、Check at all levels，Relevant experts are invited to organize a special meeting to compare and demonstrate the scheme.，Careful calculation of site bearing capacity、Crane load performance、Stress condition of steel wire rope and snap ring；Detailed disclosure shall be made to the site construction personnel and operation team.，Clear quality、Specific requirements for safety and civilized construction，At the same time, through the way of hoisting drill.，Investigate construction risk points。

The strong bear the burden，QUY650、ZCC5200STwo giant arms were lifted smoothly under the attention of leaders and colleagues at all levels of the project department.、Turn around、Landing，Finally, he was firmly in place，Lifting into the specified position with perfect fit。The successful hoisting of this major casting，Get the owner、Party a、Supervisor、The unanimous praise of monitoring and other units，It has laid a solid foundation for the subsequent beam erection construction.。

It is understood that，This bridge has high technology content.，Including welding of dissimilar steel and steel for bridge、Construction of Inclined Pylon with Arc-shaped Nine-sided Curved Surface by Vertical Rotation、350tCasting aerial millimeter-level hinge construction and other construction methods and processes。At the same time, the overall structure is elegant and slender.。Like a harp in the river.，Both classical aesthetics and modern science and technology，It will become the most important traffic in the main venue of the 2024 Chengdu World Horticultural Exposition.、The most shining bridge。
