Recently, the main steel girder of the Padma Bridge in Bangladesh, which was constructed by China Railway Group, was successfully closed, crossing the Padma River in Dhaka, the capital of Bangladesh, nurturing thousands of people along the route, but it also severely hindered cross-strait exchanges and development. In order to realize Bangladesh’s dream of “a bridge flying north and south, the sky becomes a thoroughfare”, the construction of China Railway Group came here with original technology and super equipment made in China.

The Padma Bridge has a total length of 7.7 kilometers. It is a double-deck road-rail bridge with a two-way four-lane highway on the upper layer and a single-track railway on the lower layer. It is the most difficult bridge project in the global geological environment. It was constructed overseas by Chinese companies. The largest single bridge project.

Bangladesh has a subtropical monsoon climate with a maximum temperature of about 48º in summer. The strong convective wind season is from March to May, and the rainy season is from June to September. Strong convective weather and flood disasters occur frequently. In addition, the geological environment of Padma River is complex, and the construction process is unfavorable for hurricanes, floods, and navigation channels. Conditions have brought great challenges to the erection of steel beams, which put forward higher requirements for the stability, accuracy, and corrosion resistance of the lifting equipment.

Here, Sany Crane has not only withstood the harsh high-standard inspections of the international supervision team composed of experts from the United States, South Korea, Holland, France, and other countries and the Bangladeshi military but also withstood the test of harsh construction environments such as high-temperature grilling and rain erosion. Become the main force in project construction.

Despite the difficulties, with its excellent product performance and ultra-low failure rate, Sany Crane successfully completed thousands of times of lifting and splicing of the Padma Bridge, laying a solid foundation for the closure of the Padma Bridge.
