Product Description

Product Description

The 321-Type panel bridge is a type of bridge system that can be dissembled and rapidly erected. It was designed according to British Compact-100 Bailey Bridge. The whole bridge is welded with high-tensile strength steel. The girder is lightweight composite panels and the panels are connected by panel connection pins. The conversion among the parts is easy and they are lightweight. It is easy to assemble or disassemble and transport them. It can also be assembled into different forms of panel bridges according to their span length and transportation requirement. So, it has been widely applied as a more developed and guaranteed panel bridges for emergency transportation.

Because the deck is thin and transom beam is light, It is suitable for that when the requested bridge span or loading are small.

As the international marketing developing, some international users insist to adopt the bridge in British dimension to match the old bridges, Great Wall can also provide the special-made bridges with panel dimension on 3.048mX1.45m (Holes center distance). In China, it is called British 321-Type Bailey Bridge.
