Product Types
Common types include the Type 321 steel bridge and the HD200 prefabricated highway steel bridge. The Type 321 steel bridge was developed based on the original British bailey bridge, combined with my country's national conditions and actual situation, featuring lightweight components and easy assembly and disassembly. The HD200 type increases the truss height, improving load-bearing capacity and stability.
Product Features
- Bears the main loads: The weight of vehicles and the bridge deck are ultimately converted into bending moments and shear forces acting on the bailey truss. The upper chord is under compression, the lower chord under tension, and the diagonal members under shear.
- Determines bridge span and load-bearing capacity:
Truss height (number of stories) determines bending resistance.
Truss width (number of rows) determines lateral stability.
Both together determine the width of the valley the bridge can span and the weight of vehicles it can withstand.
- Modularity and Speed: All components are standardized, connected only by pins and bolts, enabling rapid assembly and disassembly of unpowered machinery-this is its military origin and engineering value.
- High Flexibility: It can flexibly adapt to a wide range of needs, from light temporary bridges to heavy permanent bridges, through different row and layer combinations and the addition of reinforcing chords.
Application Scenarios
Bailey steel trusses are widely used in defense, war preparedness, transportation engineering, and municipal water conservancy projects. They can be used for the rapid construction of temporary bridges, meeting emergency needs in military and emergency situations, and can also be used to assemble engineering equipment such as gantry cranes, guide beams, and bridge erecting machines.
