Double ladder side long-span bridge is a kind of stepped cable bridge. The load of double ladder side long-span bridge is much larger than that of ordinary cable bridge. Because the stepped cable bridge depends on the stress and bearing of ladder side, the stress point and stress area of double ladder side increase, so the load also increases accordingly.

The double ladder side long-span cable bridge not only has strong bearing capacity, but also is strong and durable and easy to install. It is assembled from pultruded FRP profiles. Its specific gravity is much lighter than that of carbon steel. There is no need for hot work during construction, which is safe and environmentally friendly.
