Type 321 - Crossbeam for Bailey bridge: Installed on the lower chord pins of the Bailey bridge panels and secured with crossbeam clamps. Additionally, each section has one crossbeam connected to the ...
See DetailsThe Type HD200 Vertical Support Frame for Bailey bridges is the core vertical load-bearing component of the HD200 prefabricated steel bridge and heavy-duty truss system. Its primary function is to transfer vertical loads and prevent structural overturning and vertical deformation. By working in conjunction with horizontal support frames and strengthening chords, it forms a three-dimensional stable system, evenly transferring heavy loads (such as bridge traffic and construction loads) to the foundation. It is suitable for large-span (9.144-60.96m) and high-load (HS25 class and above) engineering scenarios. The product comes in two specifications, 730 type and 480 type, matching the corresponding spacing of the HD200 truss. It is widely used in bridge engineering, large formwork support systems, and emergency rescue operations. It is a core component for solving engineering problems such as excessive height-to-width ratios and insufficient foundation bearing capacity, forming a complete force-bearing closed loop with the strengthening chords and horizontal support frames of the same system, ensuring overall structural stability.
