Producing Prefabricated Steel Truss Vehicular & Pedestrian Bridges Since the 1950s
THE BAILEY BRIDGE SYSTEM
FEATURES
• Adaptable – Pre-engineered to match each application
• Fast – Modular stocked components facilitate quick assembly so the bridge is open to traffic in days.
• Lower Cost – An alternative to custom designed bridges
• Easy to handle, transport, assemble, install, and reuse
MATERIALS & FINISHES
Domestic steel is used throughout. Most load-bearing components use low-alloy, high-tensile steel with a yield point of 50,000 psi. Excellent corrosion resistance is achieved with an inorganic zinc silicate or polysiloxane coating. Final color is lusterless light gray. Hot dipped galvanized is also available on some components.
STANDARDIZED COMPONENTS
The key to the Bailey Bridge system is the ingenious set of precision-made, interchangeable steel components from which all Bailey structures are assembled.
MADE IN THE USA
The US M2 Bailey components supplied by Bailey Bridges, Inc. are either original US Army equipment or newly manufactured in the USA to those exacting specifications – utilizing domestic steel. It remains the current standard panel bridge of the US Army.
ASSEMBLY & INSTALLATION
Most Bailey Bridges are assembled and installed by a small crew in a matter of days. Common hand tools are utilized. All connections are pinned, bolted, or clamped – no field welding necessary. Disassembly is similarly easy, and components can be stored in minimal space until reused. Bailey Bridges are often installed by the cantilever launching method in which the assembled bridge together with a “launching nose” is rolled out across the gap without falsework or heavy equipment. The cantilever method allows bridges to be quickly erected over rivers or deep gorges. Additionally, some Bailey Bridges may be hoisted into place by crane.
VARIABLE CONFIGURATIONS
Bailey Bridge components can be assembled in seven different configurations to efficiently accommodate a wide range of span and capacity requirements. Panels, the primary Bailey components, are pinned together at the job site to make girders of any length. Various girder strengths are achieved by assembling either a single row of panels, two rows side by side, or three rows side by side. Panels may also be stacked double-story for further increased strength. For greatest strength, longer spans may be chord reinforced.
SPANS
For highway use, typical Bailey Bridges clear spans ranging from 20 ft to 200 ft. Multiple-span bridges of any length are possible by incorporating intermediate supporting piers.
- Speed construction – Pre-engineered stocked components
- Safety – Time-tested performance
- Modular – Fast installation and removal
- Versatility – 10 ft multiple bays use the same parts
- Cost effective to own and re-use in different length bridges
- Damaged parts can easily and quickly be replaced from stock.
