Compact-200 Bailey Bridge is similar to the 321-Type bailey bridge from their appearance. The difference is its increased panel height to 2.134m. For some bridge with longer spans, It employed the method of alternating joints between Reinforcement Chords and the joints between panels. This method can decrease inelastic deformation caused by the oversized pinholes. Pre-arch method is used to additionally cut down mid-span and vertical deflection to a larger degree. Bolt-connected components use the orienting sleeve- fixing method to increase accuracy of connections. Shear is created in orienting sleeves and tension is developed in bolts, which increase the usage life of the bolts and ensure the safety of panel bridges. Wind resistant brace is made to be composite type and is connected to transom/girders to improve overall stability of panel bridges. The part between braced frame and panels is fixed through bridging so as to prevent the whole bridge from side bending. After the erection, there will be a pre-arched degree over the span of the bridge. Besides it can be assembled into single-lane bridges. The compact 200 bailey bridge can also be assembled into double lane bridge, hence it broadens its application range. It is suitable for the load designs of HS-15, HS-20, HS-25 ,HL-93 and pedrail-50 etc.
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.
