The chain-free conveying device for persons according to the invention has directly driven step bodies (11) which run forwards in one direction one after the other and run back more quickly thereunder. Each step body (11) runs on rollers (12, 12', 13, 13'), of which two (12, 12') are each driven by a respective electric motor (14. 14'). Each step body (11) includes a device for current supply. Moreover, each step body (11) has four sensors (15, 15', 16, 16') for determining the spacing from the next step body (11). A control electronic system (18) controls the electric motors (14, 14') in dependence on the signal of the sensors (15, 15', 16, 16'), so that the step bodies (11) run directly one after the other in the region (1) for the transport of persons. A respective tipping station (3, 4) for inclining the step bodies (11) is provided at each of the ends of the conveying device for persons. In a preferred form of embodiment the step bodies are directly driven by a friction wheel drive or, however, by means of additional toothed wheels.
