Accessible assembly station, in particular assembly platform, and method for operating the same

An assembly station through which a workpiece arranged on a transport device can be moved on a defined transport path in a transport direction, the assembly station comprising:

• a first, second and third accessible platform, wherein the third platform is arranged between the first platform and the second platform;
• a first conveying slot, which is formed between the first and third platforms, and a second conveying slot which is formed between the second and third platforms, wherein the longitudinal directions of the conveying slots define the transport path;
• and
• a plurality of holding devices which are each configured to be able to assume a holding position in which they for example cross one of the conveying slots and hold the third platform in position in relation to the first or second platform,
• wherein the holding devices are configured to be moved into a release position in which they enable the transport device together with the workpiece to move through the assembly station or expose or do not cross the conveying slot which they cross in their respective holding position.
