On May 17, 2026, at the construction site of the Yan’an Road Huaihe River Bridge in Bengbu City, Anhui Province, the SHW360t bridge deck crane independently developed and manufactured by Henan Shenghua Heavy Crane Co., Ltd. accurately completed the first 248.6 ton steel box girder lifting operation, marking the key stage of the steel box girder suspension and assembly construction of the largest cable-stayed bridge in the Huaihe River Basin.
The Yan’an Road Huaihe River Bridge has a main span of 420 meters and is the largest cable-stayed bridge in the Huaihe River Basin. The entire bridge consists of 29 steel box girders constructed by suspension assembly, with a maximum lifting capacity of 248.6 tons per section. The core construction challenge lies in the high-altitude lifting of steel box girders, which requires operations under large tonnage, millimeter level docking accuracy, and complex wind conditions, with extremely strict requirements for lifting equipment. After the completion of the bridge, it will alleviate the north-south traffic pressure in the central urban area and significantly enhance the level of connectivity between the two banks of the Huai River.
The SHW360t bridge deck crane put into use this time is a specialized equipment tailored by Shenghua Group for the construction characteristics of large-span cable-stayed bridge steel box girder suspension assembly, with four core advantages:
1.Double car symmetry and force balance
Adopting a symmetrical design of 180+180t double trolley, the rated lifting capacity of the whole machine is 360 tons, and the dual machine synchronous operation ensures even force distribution, effectively avoiding lifting deformation and ensuring the integrity of the steel box girder structure.
2.Accurate sensing and millimeter alignment
The lifting mechanism is equipped with high-precision longitudinal and transverse sensors, which can collect and dynamically adjust the posture of the beam segment in real time. The precision of the first lift alignment is controlled within ± 2 millimeters, meeting the high standard construction requirements of the bridge.
3.Global monitoring and controllable security
Standard full scene high-definition video surveillance, covering all work processes without blind spots. The system has an abnormal warning function to identify and handle security risks in advance.
4.Lightweight design, reduced load and increased efficiency
The overall structure has been optimized through finite element analysis, ensuring strength and stiffness while minimizing self weight, reducing the impact of load on unformed bridges, and improving construction safety.
The “steel giant” built by Shenghua not only has excellent construction performance, but also has a full cycle value advantage that surpasses traditional equipment:
Predictive operation and maintenance, zero downtime guarantee
Based on equipment operation data and fault models, achieve a leap from “post maintenance” to “pre prevention”, providing uninterrupted support for construction.
Energy efficiency optimization and full cycle cost reduction
By adopting an efficient transmission system and intelligent energy management, we aim to reduce long-term operational energy consumption and wear and tear of vulnerable parts, thereby improving the overall input-output ratio of the project.
Module architecture and asset continuity
Adopting standardized modular design, supporting functional expansion and performance upgrades under different operating conditions, and achieving cross project reuse of equipment.
Under complex wind conditions over the Huai River, two Shenghua SHW360t bridge deck cranes operated smoothly and accurately, achieving zero error positioning of steel box girders. The project department of China Railway Fourth Bureau stated on site that the equipment performance is stable and reliable, and the operation is convenient and efficient, providing strong guarantees for the safe and efficient promotion of the project.
As a professional heavy lifting equipment manufacturer in China, this service to the Yan’an Road Huaihe River Bridge in Bengbu is another successful practice of Shenghua in the field of bridge specific equipment. In the future, Shenghua will continue to innovate in technology, provide reliable support for major national infrastructure projects with excellent products and professional services, and contribute solid strength to the construction of major national projects.
