<p>The transportable bridge has two track carriers (3) as frames with a triangular cross section with a girder profile (O,U) at each corner of the triangle. Two triangle points are at the same level with the third point above them, and with diagonal struts (D). The triangular frame structures are bonded together (K) at the upper and lower girders. The lateral track carriers (5) are locked together in a force fit and lie on the frame bonding points, locked to them in a force fit. The track planks (7) lie along the bridge length, locked to the lateral carriers with a force fit. The lateral carriers are pushed wholly through the track carriers, and are locked to them in a force fit, so that the gaps are fixed between the two frame planes at the under side of a track carrier and also the two track carriers. The lateral carriers and the track planks are formed by extruded tubular profiles of compound fiber materials.</p> |
