Elegant appearance CB100 Bailey steel bridge Easy installation Firm and Stable

Bailey Bridge Introduction

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.

321 Steel Truss Bridge is a kind of Assembly Bridge down supporting, mainly used for medium spans.

The Bailey bridge is a type of portable, pre-fabricated ,modular truss bridge.

The bridge deck is concrete used as permanent bridge.

The surface protection can be paint or hot-dip galvanized.

Bridge load capacity, width can be designed according to user's requirements.

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.

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 Bailey Bailey.
