Description of Steel Suspension Bridge
A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. The main load-bearing member of the suspension bridge is a suspension cable, which is mainly subjected to tensile force and is generally made of steel (steel wire, steel cable, etc.) with high tensile strength. Because the suspension bridge can make full use of the strength of the material, and has the characteristics of saving materials and light weight, the suspension bridge has the largest spanning ability in various system bridges, and the span can reach more than 1000 meters.
Specification of Steel Suspension Bridge
|Product Name||Specification of Compact 321-type Bailey bridge|
|Maximum span||64meter single span|
|Bridge deck||Steel composit panel|
|Loading capacity||20ton, 40ton truck etc, or HS20-44, HS25-44/Truck 20|
|Advantages||Price effective and technical full analysis and supports|
The suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into a tension in these main cables. The main cables continue beyond the pillars to deck-level supports, and further continue to connections with anchors in the ground.
The first wire-cable suspension bridge was the Spider Bridge at Falls of Schuylkill (1816), a modest and temporary footbridge built following the collapse of James Finley's nearby Chain Bridge at Falls of Schuylkill (1808). The footbridge's span was 124 m, although its deck was only 0.45 m wide.
Development of wire-cable suspension bridges dates to the temporary simple suspension bridge at Annonay built by Marc Seguin and his brothers in 1822. It spanned only 18 m. The first permanent wire cable suspension bridge was Guillaume Henri Dufour's Saint Antoine Bridge in Geneva of 1823, with two 40 m spans. The first with cables assembled in mid-air in the modern method was Joseph Chaley's Grand Pont Suspendu in Fribourg, in 1834.
In the United States, the first major wire-cable suspension bridge was the Wire Bridge at Fairmount in Philadelphia, Pennsylvania. Designed by Charles Ellet, Jr. and completed in 1842, it had a span of 109 m. Ellet's Niagara Falls Suspension Bridge (1847–48) was abandoned before completion. It was used as scaffolding for John A. Roebling's double decker railroad and carriage bridge (1855).
The Otto Beit Bridge (1938–39) was the first modern suspension bridge outside the United States built with parallel wire cables.
Spans from 60m to 300m and more - for highways, railways, pathways, bicycle racks, landscaping, etc
Standardized designs - as per Indian BIS a. RC standards and codes
Heavy live loads with high overfills - capable of supporting heavy freighter aircraft and mining haulers
Smooth approaches - from earth embankments due to soil overfill, does not require any approach slab
Low life cycle costs - traffic runs on overfill and not over an exposed bridge deck
Aesthetic structures - the true arch form is accentuated.
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
Longer main spans are achievable than with any other type of bridge
Less material may be required than other bridge types, even at spans they can achieve, leading to a reduced construction cost
Except for installation of the initial temporary cables, little or no access from below is required during construction, for example allowing a waterway to remain open while the bridge is built above
May be better able to withstand earthquake movements than heavier and more rigid bridges
Bridge decks can have deck sections replaced in order to widen traffic lanes for larger vehicles or add additions width for separated cycling/pedestrian paths.
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.
