Galvanized 321 Type Double Row Single Layer Modular Steel Bailey Bridge New Zealand Standard

Galvanized 321 Type Double Row Single Layer Modular Steel Bailey Bridge New Zealand Standard

Description

The 321-type Steel Bailey Bridge is a rapid assembly bridge developed on the basis of the original British Bailey truss bridge and combined with China's national conditions and actual conditions. It was finalized in 1965 and has been greatly developed in China. It is widely used in national defense, Traffic engineering and municipal water conservancy engineering are the most widely used assembled bridges in China. It has the characteristics of simple structure, convenient transportation, fast erection, large load capacity, good interchangeability and strong adaptability.

Specification

Three normal width bridges are as following:
3.15m width (model CB100/321): light weight and load, mostly used over middle or small span rivers.
4.2m (model HD200) width: marked both in metric and inch dimension, mostly used in International market over middle and large span rivers.
7.35m width (model HD200): two-lane bridge, widely used over various rivers.

Application

1. Standard Single Lane: Bridge deck width: 3.15m; Span length: 9.14-60.96m
2. Extra Single Lane: Bridge deck width: 4.2m; Span length: 9.14-60.96m
3. Standard Double Lanes: Bridge deck width: 7.35m; Span length: 9.14-51.816m
4. Panel Dimension: 3048MM*2134MM

Features and Benefits

Modern versions of classic “Bailey Bridge” design
Quick ship and install
Permanent or temporary application
Excellent detour bridge solution
Short-term or long-term rental options
Able to cantilever-launch from one side
Optional internal or cantilevered sidewalk

Advantage

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,which has long lifetime. Material can be recycled components, with light weight and low cost.

Installation

It is easy to mounting Bailey bridges without any help of cranes or hoists. One bridge installation can be finished only by hands of human power, using complete launching tools including roller, flat roller, roller frame, wrench and jack.
We’ll designate our professional installation team to install, or designate technical experts to guide the installation, according to customer's requirement.

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made.

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
