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. The base frame supports both each lower chord of launching support section and each lower chord of track support in a mounting manner. A height-adjustable feed drive is provided for driving the launching support after one of the bridge sections has been pushed …
