Modern Pedestrian Steel Bridge Across Railway Portable Steel Bailey Footbridge

Description

Pedestrian bridges can be useful for linking buildings or popular destinations (e.g. shopping centers, large schools, recreational facilities, parking garages, light rail stations). They are also useful for linking areas separated by highways of freeways, where at-grade crossing are not permitted. Pedestrian bridges, like any other bridge, must be long enough to clear the obstacle which is to be crossed and high enough not to interfere with whatever passes beneath the bridge.

Specification

Application

Pedestrian bridges can be used in three situations, including: (1) crossing interstate highways, (2) crossing natural physical obstacles like rivers, or (3) crossing railroads. At some intersections, a pedestrian bridge might be a better investment than a road-level crossing. These intersections may call for designs

Design
Design of pedestrian bridge normally follows the same principles as for other bridges. However, because they are normally significantly lighter than vehicular bridges, they are more vulnerable to vibration and therefore dynamics effects are often given more attention in design.
To ensure pedestrian bridges are accessible to disabled and other mobility-impaired people, careful consideration is nowadays also given to provision of access lifts or ramps, as required by relevant legislation.

Features
Provision of suitable access for wheelchairs and cyclists is often specified for pedestrian bridges. Access ramps must be provided and restricted to a maximum gradient. The consequent length of ramps where access is from the level of the road or rail track over which the bridge spans is generally much longer than the bridge itself. The form of construction suitable for the ramps may have a dominant influence on the final form of the bridge.

The width of a pedestrian bridge is usually quite modest, just sufficient to permit free passage in both directions for pedestrians. Occasionally the bridge will have segregated provision for pedestrians and cyclists, in which case it will need to be wider. Parapets are provided for the safety of both the pedestrians and traffic flow. Pedestrian bridgeS over railway lines are required to have higher parapets and be provided with solid panels directly over the rail tracks.

History
First bridges in history were pedestrian bridges and they were made of wood. Ancient Rome started making stone bridges in the 2nd century BC over the Tiber River. Some of these ancient stone footbridges with arches still stand today. One of them is Ponte Fabricio which was built in 62 BC and it still has some of its original materials. Today, modern footbridges are made of wood, rope, metal and concrete.

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.
