Bailey Bridge is a standard bridge equipment, adopted extensively and the most popular in the world

Bailey Bridge Introduction

The Bailey bridge is a type of portable, pre-fabricated ,modular truss bridge. It was developed by the British during World War II by Donald Coleman Bailey for military use and saw extensive use by both British and the American military engineering units.During 1980s,it was introduced to China From UK.

Bailey bridge is standard bridge equipment,adopted extensively and the most popular in the world,possessing the features of simple structure,convenient transport,speedy erection and easy disassembling.While having the advantage of heavy loading capacity,great stability and long fatigue life being capable of an alternative span,long capacity and mixture form to erect all kinds and usage of temporary bridges,emergency bridges and fixed bridges.The bridge has the advantages of few components,light weight and low cost.

We have two producing lines to manufacture Compact-100( 321-Type) and Compact-200(200-type)

The surface disposal is painting,galvanized or anti-skid wearing such as a polyurethane bonded bauxite chip system or similar according to the requirement.

Advantages

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


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. Steel bridge generally USES factory, site splicing, the construction period is short, processing convenient and not affected by seasonal effect.
4. Steel bridge is suitable for industrialized manufacture and very convenient to transport.
5. Steel bridge is easy to repair and replace,long lifetime,material can be recycled.


Application

Beam bridge,arch bridge,rapid frame bridge,cable-stayed bridge,suspension bridge. passenger foot-bridge


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 elements
are small enough to be carried in , and the bridge is strong enough to carry . It is considered a great example of military engineering.

Compact-100 Bailey Bridge Specification and Typical Configuration

Compact-100 Bailey Bridge
Model Alias:100-Type; China 321-Type
Model Derived: CB100,Compact-100,British 321-Type
Bridge deck net width: 4m
Maximum Free Span length: 51M
Panel Dimension:3000MMX1400MM(Holes center distance)

The 321-Type panel bridge is a type of bridge system that can be dissembled and rapidly erected. It was designed according to British Compact-100 Bailey Bridge. The whole bridge is welded with high-tensile strength steel. The girder is light weight composite panels and the panels are connected by panel connection pins. The conversion between the parts is easy and they are lightweight. It is easy to assemble or disassemble and transport them. It can also be assembled into different forms of panel bridges according to their span length and transportation requirement. So, it has been widely applied as a more developed and guaranteed panel bridges for emergency transportation.
Because the deck is thin and transom beam is light, It is suitable for that when the requested bridge span or loading are small.
As the international marketing developing, some international users insist to adopt the bridge in British dimension to match the old bridges, Great Wall can also provide the special-made bridges with panel dimension on 3.048m X 1.45m (Holes center distance). It is called CB100 or Compact-100 Bailey Bridge, In China, it is called British 321-Type BaileyBridge.

Span-Load Table Configuration

ZhengJiang Great Wall Heavy Industry Technology Co.ltd (here and after called Great Wall ) is locacted at Zhengjiang city, South of Yangtze River, belonging to Yangtze River Delta economic zone, owning railway station of Shanghai-Nanjing and Shanghai-Beijing High-speed raillways; 30 kilometers away from Zhenjiang seaport, 50 kilometers away from Changzhou airport, 70 kilometers away from Nanjing airport,and YangzhouTaizhou airport; Great Wall has passed ISO Quality Management System Certificate; its WPS and welders have passed BV certification; the raw material and finished products are accepted by International Third Testing Institute such as SGS,CCIC,CNAS etc; In addition,Great Wall has several independent R & D patents

321-Type（British Compact-100） prefabricated highway steel bridge and 200-Type prefabricated highway steel bridge ( Bailey bridge) are main products of Great Wall, which has a full set of components production line for complete bailey bridge set. More than this, Great Wall has developed a kind of large span prefabricated D-Type bridge whose single span can be up to 91 meters, and has completed the load test already and engineering application of the whole bridge.

Great Wall has the surface treatment process of sand blasting, dip coating, spray painting, hot dip galvanizing, zinc aluminum alloy coating,etc with the annual output of more than 10000 tons.

Great Wall has good cooperation relationships with China Communication Group, China Railway Group, Powerchina Corporation, GEZHOUBA Group, CNOOC etc huge state-owned Key Enterprises in railway, road, international government procurement projects, and is also enthusiastic about the public welfare, such like supporting Hongkong Wu Zhi Qiao (Bridge to China) Charitable Foundation, building up all the footbridges for them and supporting China Shanxi TV building Charity Bridge for remote village.

Great Wall steel bridge is not only well- known in China, but also won good reputation overseas; the bridges made by Great Wall have been used all over the world exported to Indonesia, Nepal, Republic of the Congo, Myanmar, Mongolia, Kyrgyzstan, Mexico, Chad, USA, Trinidad and Tobago, Mozambique, Tanzania，Kenya, Ecuador , Dominica etc.

Furthermore, Great Wall has developed the container movement set independently, undertakes heavy steel structure fabricating business, promotes mechanical galvanization process for fastening parts.

The container movement set is not only supplied to domestic airplane manufacturing company, but also exported to country Haiti and so on meeting the demands of moving container in airport dock. The box girder, plate girder, guard rail such steel structures made by Great Wall are also well approved by clients. Great Wall mechanical galvanizing process made up the deficit of electroplating and hot galvanizing, showed extraordinary performance in field of environmental galvanization.

Great Wall considers the quality as company’s life, always accumulates the industrial experience of production and quality, improves production technology and efficiency, follows international specifications to control the quality, improves international competition, supplies the superior products and the best service to the clients with high standard, good quality and branding strategy.
