This invention relates to a transport system for moving at least one automated maintenance device for large substantially perpendicular surfaces, for example ship hulls, comprising a monorail system which can be laid freely and at least one drive device which can be moved on the monorail system along a movement direction. The at least one drive device has a drive unit with at least one running wheel, and the running wheel can be driven via at least one drive, preferably an electric drive. At least one pressing unit, is provided which is connected to the drive unit). The at least one pressing unit has at least one loading roller which can be pressed onto the monorail system via at least one spring element, and/or a fixing device is arranged on the drive unit, wherein a fixing roller is provided which interacts with the monorail system.

A solution is provided for the problem of holding an apparatus against a metallic hull of a vessel or an offshore unit. Described is a holding means, comprising: at least one magnetic means for exerting a pushing force on the apparatus to-wards the metallic surface; and a moving means for moving the apparatus on the metallic surface, in which the moving means is arranged to bear the pushing force from the at least one magnetic means, on the metallic surface. Also disclosed, is an apparatus including such a holding means. The holding means allows to bear the pushing force from the magnetic means, on the metallic surface, at the same time it allows the apparatus to move on it.

The robotic device conducts an action on a curved ferromagnetic surface. The robotic device includes a chassis platform and at least one magnetic side drive module. The chassis platform rolls on the curved ferromagnetic surface and is maintained thereon by virtue of the curved ferromagnetic surface being ferromagnetic. The at least one magnetic side drive module is pivotally attached to the chassis platform and is for conducting the action on the curved ferromagnetic surface as the chassis platform rolls on the curved ferromagnetic surface.
