Zhenjiang Tongkai Mechanical Engineering Co., Ltd.
Bailey Bridge is a standard bridge equipment, adopted extensively and the most popular in the world
Advantage of Bailey Suspension Bridge
Possessing the features of simple structure.
convenient transport, speedy erection
easy disassembling.
heavy loading capacity,
great stability and long fatigue life
being capable of an alternative span, loading capacity
Temporary Construction Bridge Features
1. High strength and big stiffness , relative to the concrete bridge can be reduced trabecular high and self-respect
2. Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make steel bridge in the working condition and calculation compared with the assumption
3. Bailey Temporary Construction Bridge generally USES factory, site splicing, the construction period is short, processing convenient and not affected bv seasonal effect.
4. Steel bridge is suitable for industrialized manufacture and very convenient to transport.
5. Steel Bailey Suspension Bridge is easy to repair and replace, long lifetime, material can be recycled.
Mixture form to erect all kinds of
Temporary Bridges, Emergency Bridges and Fixed Bridges Using the bridge equipment, the suspension bridges of varied span can be erected The bridge has the advantages of few components, light weight and low cost .Bailey Bridge requires no special tools or heavy equipment for construction, the bridge elementsare sma enouch to be carried in , and the bridge is strond enouch to carrv , it is considered a oreat example of militarvengineering.
The compact 200 panel bridge: The compact 200 panel bridge is similar to the compact 100 panel bridge from their appearance. The difference is its increased panel heicht to 2.134m. lt employed the method of alternating joints between Reinforcement Chords and the joints between panels. This method can decrease in elastic 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 sleeve- fixing method to increase accuracy of connections. Shear is created in thesleeves and tension is developed in bolts, which increase the usace 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 overastability of panel bridges.
Competitive Advantage:
Heavy loading capacity
Used as permanent bridge
Great stability
Large span
Long service life
Beautiful appearance

Product Performance:
It is a type of bridge which can be used as a permanent or semi-permanent bridge over wide rivers, bays, canyons and mountainous areas, it can also be used as temporary construction bridge.
Application
Suspension bridges are often used to cross rivers, valleys, bays, as well as valleys, cliffs, and other mountainous areas with complex terrain. It is often used as a permanent or semi-permanent steel bridge, and can also be used as a temporary multi-purpose steel bridge. The design height of the suspension bridge can be increased as required to allow surface ships to pass under the bridge. The construction of the Bailey suspension bridge does not require the construction of temporary piers.
