The compact 200 Bailey bridge is an upgraded steel structure prefabricated bridge based on the compact 100 Bailey bridge. The appearance is similar to the compact 100-type Bailey bridge. The height of the truss is increased from 1.448 meters to 2.134 meters, and the load-bearing capacity and strength have been increased. Therefore, it is more suitable for use under heavy load. The 200-type compact Bailey bridge supports two lanes, which greatly expands the scope of use of the bridge.
The reinforced chord design of the compact 200 Bailey bridge is divided into two types: light and heavy, which can be selected according to the load of the bridge. The compact 200 Bailey bridge adopts the staggered arrangement of the joint between the reinforced chords and the joint between the truss to reduce the inelastic deformation caused by the pinhole gap. The horizontal support frame of compact 200 Bailey bridge is fixed by straddle connection with the Bailey panel, so as to ensure that the whole bridge has no side bending. The 200-type compact Bailey bridge is mostly used in permanent and semi-permanent Bailey bridge solutions.
Compact 200 Series Prefab Bridges
AGICO’s compact 200 series fabricated steel bridges are available in a variety of models, including HZCB200, HZCB200A, HZCB250 and HZZB200. Among them, the HZZB200 steel truss bridge is a through bridge connected by a single pin truss structure girder. This series of fabricated truss steel bridges are mainly used for quickly erecting temporary bridges, ensuring heavy vehicles quickly overcome the obstacles of rivers, broken bridges, ditches, valleys, and so on. They are widely used in the field of emergency rescue and disaster relief.
| Model | Design span | Bridge truss height | Deck material | Net width of bridge deck | Sidewalk | Design load |

| CB200A | 6~60m (The bridge length can be changed by 3.048m) | 2.134m | Steel deck | 4.2m、7.35m | 1m external sidewalk | HL-93,HA,HB,Highway ClassⅠLoad, Tracked vehicle 50 tons, etc. |
| CB250 | 35~87.6m (The bridge length can be changed by 5.84m) | 2.4m | Steel deck | 4.2m、7.35m | external sidewalk | HL-93,HS20-44, HS25-44, HA,HB,Highway ClassⅠLoad, Tracked vehicle 50 tons, etc. |
| ZB200 | Single span 6.09~60.96m | / | Steel deck | 4.2m、7.56m | / | Tracked vehicle 50 tons, Wheel axial compression13 tons. |
The compact 200 series truss bridge adopts a modular design and has excellent interchangeable connectivity. Many countries around the world have purchased compact 200 prefabricated highway steel bridges as temporary or semi-permanent bridges. Its application has been expanded from pure military use to civil highway bridge fields.
Wide use: It can also be used as various construction platforms, such as suspension bridges, suspension bridges, construction trestle bridges, cast-in-place formwork supports, bridge erectors, large-tonnage gantry cranes, etc.
Performance features：Fast erection, short construction period, large span. The bridge parts can be reused many times.
Structure Classification of Compact 200 Series Truss Bridge
The compact 200 series steel bridge supports the combined design of double-layer and multi-row truss structures. According to the different span and load, the number of erection rows of compact 200 truss bridge supports the combination of 1 to 4 rows. Single-layer or double-layer can be selected. At the same time, it supports the design of two lanes. In addition, the sidewalk of 1m or 1.2m can be set outside.
The specific structural configuration of the steel bridge will also be designed according to your local environmental factors. These factors include changes in temperature, the frequency of earthquakes, inland or coastal, and the presence or absence of hurricanes. Welcome to consult our experts for free Bailey bridge design.
