Product Detail

Modular Long Span Bridge/ Assembling Steel Panel Bridge ADVANTAGES

It is easy to install. Each part of the Bailey bridge is a standard machine made piece and is interchangeable among spans. Inmost cases, no heavy equipment is required to assemble or launch a Bailey bridge; only basic pioneer skills and equipment are needed.

It is highly mobile. All parts of the bridge can be transported to and from the bridge site by 5-ton dump trucks and trailers.

It is versatile. Standard parts can be used to assemble seven standard truss designs for efficient single spans up to 210 feet long and to build panel crib piers sup porting longer bridges. With minor non standard modifications, the expedient uses of bridge parts are limited only by the users imagination.
