Abstract (en)

[origin: EP0340409A1] Portable bridge, in particular for military purposes, consisting of a plurality of interconnectable bridge elements (B), including deck slabs (F), bottom flanges (U) and diagonal struts (D). According to the invention, the bridge is higher in its centre than at its ends, this being achievable by means of length-adjustable component parts (F, U, D). This design reduces the weight in such a way that even long bridges can be transported on a single vehicle. <IMAGE>
