Abstract: Boom of a laying mechanism of a bridge laying vehicle, the laying mechanism being composed of a placement arm and the boom. The boom includes a base member that can be fixedly secured to the vehicle by at least one securement device. A jib, especially with locking elements for locking a bridge element in place, is moveable relative to the base member. A pivot member is pivotably disposed on the base member, and the jib is pivotably disposed on the pivot member. Pursuant to the method for moving the boom into a vehicle transport position, the jib is pivoted about a pivot axis in the forward direction of travel by raising the pivot axis of the jib.

Abstract: A device for assembling and laying track support bridge sections displaceable at right angles to their longitudinal axis, with launching support structures, which are arranged between the track supports and are likewise transversely displaceable, into a bridge support structure. The device includes a base frame with a plurality of telescoping props, base frame being built up on a vehicle. A laying arm is provided pivotable around a horizontal axis at one end of the base frame. A front arm is provided pivotable around a horizontal axis at another end of the base frame. Both the laying arm and the front arm are adjustable by hydraulic cylinders. A displacing device is provided for pushing the bridge sections apart and together. The displacement device includes track support and launching support sections arranged between the front arm and the laying arm on the base frame in a transverse direction in relation to the base frame.
