ABSTRACT:
A bridge laying apparatus of the type having a vehicle and at least two bridge sections which are transportable thereon in a superimposed position and are joinable into a bridge for spanning an obstacle by devices carried by the vehicle. The bridge includes plural tracks connected to one another via crossbeams and the device is arranged and guided between the bridge tracks and includes a launching girder that is partially embedded within a laying beam and supported by roller pairs arranged on both sides of the launching girder, a respective one of the rollers of these roller pairs serving for guiding and supporting the bridge on the laying beam and the other roller of the roller pairs serving for guiding and supporting the launching girder in the bridge. A guide arm is articulated to the vehicle and the laying beam is held thereon by rollers which enable longitudinal displacement of the laying beam on the guide arm. The guide arm is shiftable about a horizontal axis by way of a hydraulic cylinder unit. The bridge can be laid in place with or without the use of the launching girder, depending upon the length of the obstacle spanned thereby.
