ABSTRACT:
Assembled track sections are replaced with a mobile apparatus moving along the track and having an elongated overhead girder extending above a transport vehicle or vehicles and projecting beyond an end thereof. A guide track extends in a transport plane along the girder and a trolley is mounted on the guide track for movement therealong, the trolley including a vertically adjustable hoist for lifting and lowering a respective track section and for conveying it along the guide track in the transport plane. Gantry supports for the girder project laterally beyond the longitudinally extending sides of the vehicle(s) for leaving therebetween a transverse space for permitting the passage of an assembled track switch section therethrough, the gantry supports including supports mounting the girder on the vehicle(s) and vertically adjustably supporting the projecting part of the girder on the ballast bed. The gantry supports are laterally adjustable transversely to the elongation of the girder and in a plane substantially parallel to the transport plane.
