ABSTRACT:
A bridge deploying vehicle includes a deployment arm mounted on the vehicle for pivotal motion. The deployment arm has a length dimension and a frontal end oriented toward a bridge end while the bridge is being handled by the deployment arm. A first roller assembly formed of a plurality of rollers is pivotally mounted on the deployment arm for pivotal motion relative thereto about an axis perpendicular to the length dimension of the deployment arm; and a second roller assembly formed of a plurality of rollers is pivotally mounted on the deployment arm for pivotal motion relative thereto about an axis perpendicular to the length dimension of the deployment arm. The first roller assembly is closer to the frontal end of the deployment arm than the second roller assembly. During handling of the bridge by the deployment arm, the first and second roller assemblies enter an entrance pocket at the bridge end and are guided onto a runner rail mounted on the bridge. An angle measuring device is mounted on the deployment arm for measuring an angular position of the first roller assembly relative to the length dimension of the deployment arm. There is further provided a length measuring device mounted on the deployment arm for measuring a distance between the first roller assembly situated on the runner rail and the entrance pocket.
