The grand super project of a major nation has been flawlessly completed and successfully put into operation! With the final steel box girder smoothly lifted and accurately positioned, the main bridge of the Bengbu Yan’an Road Huai River Bridge\u2014the largest-span cable-stayed bridge in the Huai River Basin\u2014has been successfully closed, achieving seamless connectivity between the north and south bridge decks.
After over a hundred days of day-and-night\u575a\u5b88, from the initial suspension to the final closure, the cantilever assembly and alignment of all 29 steel box girders of the bridge were meticulously executed under the guidance of the SHW360t bridge deck lifting and stabilization system, developed and customized by Henan Shenghua Heavy Machinery Co., Ltd., ensuring the super-engineering project’s flawless completion to the highest standards.<\/p>\n\n\n\n

The Yan’an Road Huaihe River Bridge in Bengbu has a main span of 420 meters and a main tower height of 141 meters, making it the largest cable-stayed bridge in the Huaihe River Basin. The characteristics of ultra large span and high-altitude operations near water face multiple rigorous tests throughout the entire process:
The wind conditions on the river are complex: turbulent high-altitude airflow can easily cause heavy steel box girders to sway and shift;
The construction window period is extremely short: steel box girders are sensitive to temperature, and precise closure operations can only be carried out in low temperature environments at night;
The lifting tonnage is large and the precision is extremely high: the first steel box girder weighs 248.6 tons, and the assembly of the entire bridge requires strict control of millimeter level errors.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In response to the pain points of large-span cable-stayed bridge construction, Shenghua Group has developed the SHW360t dedicated bridge deck crane, which is suitable for the construction needs of this project with super large tonnage, ultra-high precision, and high safety factor. The four core performance indicators have become the key to ensuring the quality and quantity of the project:<\/p>\n\n\n\n

01 Stable
80+180 ton double trolley symmetrical design, with a rated lifting capacity of 360 tons for the entire machine. Double car synchronization, uniform force distribution, no deformation or deviation during lifting.
02 Accurate
Equipped with a high-precision sensing system, the beam section posture is dynamically adjusted in real time, and the first lift alignment accuracy is controlled within \u00b1 2 millimeters, achieving a true millimeter level bridge construction standard.
03 Safety
Full scene high-definition monitoring with full coverage, traceable throughout the operation, warning of abnormalities, and controllable safety for high-altitude water facing construction.
04 Light
Finite element structural optimization design, lightweight and weight reduction while ensuring equipment strength and stiffness, effectively reducing the load pressure on the unfinished bridge body.<\/p>\n\n\n\n

From the successful hoisting of the first steel box girder to the perfect closure of the main bridge in September, the Shenghua SHW360t bridge deck crane operated stably throughout the entire process, efficiently completing the 29 section steel box girder suspension assembly and multi wheel precise alignment tasks. With equipment strength and professional technical services, it overcame the key and difficult points of large-span bridge construction.
After the bridge is opened, it will completely break through the traffic bottleneck on both sides of the Huai River in Bengbu, optimize the urban road network, and empower regional economic development.<\/p>\n\n\n\n
