In the vast Longdong area，The wind is cold and cold，Through layers of fog，Overlooking the Malian River Bridge，Jade belt embedded in the Loess Plateau，The piers standing beside the river are like roots.“Optimus Prime”，XugongS1 series tower crane is in full swing and accelerating construction，Create a Model of Bridge Construction with Passion of Struggle。

The Malian River Bridge isGKey Control Project of Xihe Highway of Line 309，The total length is 2208 meters，The main bridge is 1400 meters long.，BothThe loess area has the largest span in China、Low-pylon cable-stayed bridge with the largest number of spans，Also at presentThe tallest multi-dwarf tower at home and abroadPCGirder cable-stayed bridge。

Local Gale 、Heavy fog is in the majority，Bridge construction needs to cross complex geological conditions.Loess gully zone，The construction is difficult.。“The hills are rolling here.，The ravines crisscross，When selecting the tower crane，Security and stability are the first factors we consider.，The requirements for the operation of the tower are also relatively high.”，Zhang Zheng, Manager of General Contracting Department of Xihe Highway Project, said.。

Bad weather、Complex working conditions，In addition, the construction volume of the Malian River Bridge is large.，Box girder reinforcement、There are many guard plates，Especially2.5mHoisting of large-diameter pile pier、Hoisting of steel bars at a height of 240m，XugongXGT7026-12SFrom the erection of the tower to the construction, it has withstood many challenges.。

XugongS1 series products adopt modular design of structural parts，Application Technology of High Strength Cold-formed Steel，More reasonable stress of the whole machine。In windy weather，Even at an altitude of 240 meters，XugongXGT7026-12S1 can alsoHoisting with stable hook，The slewing operation is stable without shaking.、There is no back swing of the parking boom，And that construction safety is ensure，Tower Group Construction Helps Improve Hoisting Efficiency30%。

Except for the help of the group towers，The Malian River Bridge project also usedSix XCMGSC200/200FS1ConstructionElevator，Zero downtime、Zero failures，The performance of the whole machine is superior，ApplicationNovel high-reliability transmission mechanism and high-efficiency gear reduction motor，Achieve smooth operation，Safeguard reinforcement、Transportation safety of cement and other building materials，And that construction efficiency is improve。

XCMG will focus on customer needs，Continuous innovation，Continuous iterative upgrading of products，Improve product operation efficiency，Create more value for customers，Provide more perfect construction experience for bridge engineering construction。
