The invention relates to a system for the surface treatment of objects, comprising a treatment cabinet having an entry and an exit and a conveyor system comprising pulling or pushing means, by means of which an object can be conveyed in circulation in a transport direction through the treatment cabinet, thereby covering a transport distance. The object provides a transport length in the transport direction associated therewith, and the pulling or pushing means provide a drive distance in the transport direction. The conveyor system comprises a coupling device, by means of which the object can be coupled to the pulling or pushing means along the drive distance. The drive distance is shorter than the transport length of the object in the transport direction, and the coupling device is aligned so that the transport distance that can be covered by the object is longer than the drive distance.
