    • 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.
    • 一种桥式铺设设备,具有车辆和至少两个桥接部分,其可叠加位置可移动到其上,并且可连接到用于跨越由车辆携带的设备的障碍物的桥梁中。 桥梁包括通过横梁彼此连接的多个轨道,并且该装置在桥梁之间布置和引导,并且包括部分地嵌入铺设梁内并由布置在发射梁的两侧上的辊对支撑的发射梁 这些辊对中的一个辊子用于引导和支撑铺设梁上的桥,并且辊对的另一个辊用于引导和支撑桥梁中的发射梁。 引导臂铰接到车辆,并且铺设梁通过辊子保持在其上,这使得铺设梁能够在引导臂上纵向移动。 引导臂可以通过液压缸单元绕水平轴线移动。 根据所跨越的障碍物的长度,桥梁可以放置或不使用发射梁。
