The Bailey System


Bailey bridges are built on site from a pre-engineered system of ready-to-assemble components. Utilizing standardized prefabricated components, Bailey bridges can be built to match a wide range of vehicular bridging applications. Because of their excellent versatility and overall value, thousands of Bailey bridges have been installed throughout the world.

Features


1? Adaptable - pre-engineered to match each application
2??Fast - modular stocked components, open to traffic in days
3? Lower Cost - an alternative to custom designed bridges
4? Easy - to handle, transport, assemble, install and reuse

Materials and Finishes

?

Most load-bearing components use low-alloy, high-tensile Q345B steel.?Excellent corrosion resistance is achieved with an inorganic zinc silicate coating. Final color is lusterless light green. Hot dipped galvanized is also available.

Standardized Components

?

The key to the Bailey system is the ingenious set of precision-made, interchangeable steel
components from which all Bailey structures are assembled.

Ease of Assembly and Installation

?

Most Bailey bridges are assembled and installed in a matter of days by a small crew. Common hand tools are utilized. All connections are pinned, bolted or clamped. No welding is 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 Configuration


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, or two or three rows side-by-side. Panels may also be stacked in double-story height for further increase strength. For greatest strength, longer spans may be chord-reinforced.

Spans


For highway use, typical Bailey bridge clear spans range from 20 ft to 200 ft. Multiple-span bridges of any length are possible by incorporating intermediate supporting piers.

The Bailey Bridge is a safe, proven answer to diverting or detouring traffic for construction. A perfect solution, a temporary Bailey Bridge detour for the contractor:

?

1. Speed construction – pre-engineered stocked components
2. Safety – time-tested performance
3. Modular – fast installation and removal
4. Versatility – 10’ multiple bays use the same parts
5. Cost effective to own and re-use in different length bridges
6. Damaged parts can be easily and quickly replaced from stock
