What kind of loadings can I expect to take across my Railspan® bridge?
For planning purposes, we will generalize by saying that most of our Railspan® bridges utilizing two matched units placed in use side-by-side for spans up to 80 feet have been successfully calculated to support HS20-44 loadings (a legally loaded highway semi-truck). All typical concrete mixers and rural fire engines fall into a bridge loading category that is less than HS20-44. Many factors play a role in determining the amount of weight that your Railspan® bridge will support, such as the length of clear-span, the axle configuration of the vehicular traffic crossing the bridge, and the speed of the traffic to name just a few.
