Bailey Bridge is a steel truss structure bridge, which is mainly composed of standardized truss components and cross beams, longitudinal beams, bridge decks, bridge seats, and connectors. The main feature of bailey bridge is modularization, which is more convenient and widely used, and can be quickly assembled on the spot into a truss bridge suitable for various spans and loads.
Kaichaungxing are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Because the Bailey Bridge has the characteristics of modularity, the construction period is very short, and a temporary bridge can be quickly built at the location of a road collapse or across a mountain torrent river for the transportation of materials and the passage of people.
During the 5.12 earthquake in , a large number of Bailey bridges were used for emergency rescue and disaster relief. The Bailey bridge played a key role in the forward transportation of anti-earthquake relief materials, the evacuation of the wounded and the evacuation of the masses.
The extensive application group of Bailey Bridge is also prefabricated highway bridges, which are used for crossing rivers, crossing rivers and valleys. The components of Bailey Bridge are made of high-strength steel and built with trusses and beam structures. The main trusses can be single-row, double-row or three-row to improve the load-bearing capacity.
In addition, the fabricated steel bridge has a simple structure, good interchangeability, easy disassembly and maintenance, and is suitable for traffic engineering.
Dangerous bridge means that the main structure of the bridge is severely damaged and cannot be used without reinforcement. The modularity of Bailey Bridge allows its components to flexibly form part of the steel bridge body of different lengths or widths, which can be installed outside the old bridge or replaced with damaged parts, and finally achieve the effect of bridge reinforcement.

Bailey bridge is a modular prefabricated steel bridge, which is connected by steel Bailey panels through bolts and other fasteners. Its simple structure makes it especially suitable for scenarios requiring rapid bridge construction. Bailey Bridge, also known as a prefabricated road steel bridge, was invented by British engineer Donald Coleman Bailey in . It uses high-strength steel as a material and is manufactured into a lightweight standardized bridge unit construction, including beams, longitudinal beams, bridge decks, bridge seats, and connectors. The site can be quickly assembled into a Bailey bridge of various spans and loads with only dedicated installation equipment. The Bailey bridge was originally used in the military bridge field, and it has been widely promoted in the civilian field since the s. Common models include the compact 100 Bailey bridge and the compact 200 Bailey bridge.
Compared with Bailey bridge technology, traditional bridge-building technology occupies a large area, has high manufacturing costs, consumes more manpower, and has a long construction period. The biggest feature of Bailey bridge technology is the assembly type, which means that it can be assembled and disassembled on-site, which is convenient and flexible. The components can be production standardized in the factory in advance, which greatly improves the production efficiency of bridge building, is safe and efficient, and reduces costs. Because of standardized production, the quality is more stable and reliable.
The smallest modular unit in the Bailey bridge is the Bailey panel, which is a rectangular Bailey structure welded from steel frames. It can be used to splice and assemble Bailey bridges of different structures. According to the different types of Bailey panels, their size also changes. The Bailey beam is a truss beam composed of Bailey panels. The Bailey panels are fixed by bolts and cooperate with other structural parts for rapid bridge erection. The Bailey bridge is not only fast to erect, but also very fast and convenient to dismantle and has strong mobility. Therefore, it is often used in simple bridges and temporary constructions, as well as permanent bridges.
Bailey bridge is a technological revolution in the history of the development of bridge technology. Because the Bailey bridge has obvious advantages over traditional bridges, so it is widely used in traffic engineering, railway engineering, and water conservancy projects. The supporting structure composed of Bailey panels can also be used for construction brackets such as cast-in-place beams or crane towers.
In China, AGICO is the largest manufacturer in the Bailey bridge market, and it is on the list of high-quality suppliers for the engineering giants of state-owned enterprises. Through the cooperation with China’s most powerful engineering giants, it has continued to grow and has successively participated in the construction of many major engineering projects in China, such as the Hong Kong-Zhuhai-Macao Bridge, Nantong Yangtze River Bridge, and Fuzhou-Xiamen Railway.
In the international market, the Bailey bridge produced by AGICO has successively settled in Africa, South America, Indonesia, Malaysia, Thailand, and other Southeast Asian markets. Last year, AGICO successively received orders from customers in Pakistan, Panama, Colombia, and other countries.
