Muti-span Steel Truss Bridge Construction Working Bridge Heavy Load
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.
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
Prefabricated Steel Bridge (PSB), as we know, is popularly called
Compact 100 (CB100/321) and Compact 200 (HD200/CB200) bridges in
international market. Such bridge is mostly used as temporary
purpose, such as to strengthen existing bridge, launch emergency
bridge, facilitate remote area transport, and extend highway etc.
Bridge types: SS, SSR, DS, DSR, DD, DDR, TS, TSR, TD, TDR, QS, QSR,
There are 3 main pieces for Bailey bridge:
A. Panels: when assembled, they formed the 2 sides of the bridge.
Each of these panels was 10feet (3.048m) long.
B. Transom: linking the panels 2 by 2 in order to “lock” the two
side walls together.
C. Deck: made of steel pieces and put on the transoms. Decking
width is 800mm or 1000mm.
There are two sizes of truss panels available in China,, namely
3m*1.5m and 3m *2.2m. It can be assembled into 3.15m, 4.2m and
7.35m width single-lane and two-lane bridges. Bridge type shall be
decided as per customer’s requirement, especially the span, width
and load etc. factors.
