Product Description

Product Description

The introduction of GWD-Type truss prefabricated bridge stems from the technical barriers and deficiencies of Bailey Bridge. As is known to all, Bailey Bridge is a common prefabricated steel bridge structure, which is the upper and lower bearing bridge beam with the single pin connecting truss unit as the main beam of the bridge span structure, which has the advantages of simple structure, strong adaptability and good interchangeability. But even if the load is not large, it can only reach 60 meters per single span.

Therefore, Great Wall Heavy Industry launched the GWD-Type bridge. Although the truss adopts larger steel, the structure is simpler, which not only has the advantage of strong adaptability of prefabricated Bailey steel bridge, but also makes up for the limit of span, improves the length of single span and saves the cost of bridge pier.
