An overhead conveying device for integration in an assembly plant in order to transport components, said overhead conveying device having a supporting framework and a conveying device mounted on the supporting framework. The supporting framework and the conveying device form a conveying corridor, in which the components can be transported in a direction of the conveying corridor from an input point to an output point. The device further includes support columns supporting the support framework. A free space, which is suitable for component assembly and/or component transport and which can be walked and/or driven through, is formed beneath the supporting framework. The supporting framework is formed from at least two supporting framework modules arranged one after another in the direction of the conveying corridor.
