Main Rental Models and Applications of Bailey Bridges

Bailey bridges are primarily categorized into two major types: Prefabricated Highway Steel Bridge (Type 321) and Prefabricated Highway Steel Bridge (Type 200), with the latter offering greater load-bearing capacity.

A comparison of common models is as follows:

Model / Alias Truss Unit Dimensions (Height x Length) Characteristics and Typical Applications
Type 321 (Standard) 1.4 meters x 3 meters The most common model with strong versatility. Suitable for construction access bridges, temporary bridges, overpass bridges, and support platforms with medium load requirements.
Type 200 (Reinforced) 2 meters x 3 meters Features increased truss height, providing greater load-bearing capacity and stiffness. Suitable for heavy-duty access bridges, support for large equipment, and long-span temporary structures.
