The worn-out first track component is loaded onto the further rail vehicle or the at least one rail car by means of the portal lifting devices and then transported away on the track.
  • a method according to claim 36 ensures simple, quick and safe maintenance. Rail components and / or switch components are long and heavy and can be replaced easily, quickly and safely for maintenance with the method according to the invention.
  • a method according to claim 37 ensures simple, quick and safe maintenance. Maintenance work in a tunnel is particularly difficult because the maintenance work must be carried out in an extremely cramped work space. Because unloading and / or the portal lifting devices are loaded by means of the gripping device at one end of the rail vehicle and the portal lifting devices are in a compact transport state during unloading and / or loading, the unloading and / or charging only requires a comparatively small working space. By moving the at least one extension beam and moving at least one support on the crossmember and the height adjustment of the supports, the portal lifting devices can be adapted in the operating state in the desired manner to the available work space. Since the track components to be replaced are handled by the lifting units between the supports of the respective portal lifting device, the working space occupied by the portal lifting devices is sufficient to replace the track component.

Les moyens de levage portique (P1 à P6) peuvent être transportés, chargés et déchargés de manière simple, rapide et fiable, au moyen du dispositif de chargement (8). Un moyen de préhension (16) est utilisé pour le chargement et le déchargement. Les moyens de levage portique (P1 à P6) comprennent chacun une barre transversale (42) et des montants (43, 43') qui y sont disposés, lesquels moyens de levage portique peuvent être amenés de manière simple, rapide et fiable, d'un état de transport à un état de fonctionnement. Les moyens de levage portique (P1 à P6) comprennent chacun un mécanisme de levage (44) pour la manipulation de composants de voie ferrée.
