CB100 bailey Sway Brace
It can be bended and adjust the length, easy to transport.
There is one pinhole on each end of the sway brace, with pin for hanging chains, connecting sway brace and truss by pin. There is a connecting clamp in the middle of sway brace, so as to bend the sway brace for convenience of transport. There is also turn buckle on the sway brace for adjusting the length of brace. In the turn buckle, there is length indicator collet, turning the buckle to brace end in touching with length indicator collet means the brace is in proper length. One end of the turnbuckle, there is locknut, preventing brace from releasing.
Two sway braces are set to the cross of two trusses, assuming the lateral wind-force to the bridge vertically. While installing brace, keep in proper length, tighten the nut, so as to keep the bridge straight and assume wind-force effectively.
Bailey Bridge Specification
The Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed by the British during World War II for military use and saw extensive use by both British and the American military engineering units.
A Bailey bridge had the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without requiring the use of a crane. The bridges were strong enough to carry tanks. Bailey bridges continue to be extensively used in civil engineering construction projects and to provide temporary crossings for foot and vehicle traffic.
The success of the Bailey bridge was due to its unique modular design, and the fact that one could be assembled with minimal aid from heavy equipment. Most, if not all, previous designs for military bridges required cranes to lift the pre-assembled bridge and lower it into place. The Bailey parts were made of standard steel alloys, and were simple enough that parts made at a number of different factories could be completely interchangeable. Each individual part could be carried by a small number of men, enabling army engineers to move more easily and more quickly than before, in preparing the way for troops and matériel advancing behind them. Finally, the modular design allowed engineers to build each bridge to be as long and as strong as needed, doubling or tripling up on the supportive side panels, or on the roadbed sections.
