Abstract: A chain-free conveying device for persons has directly driven step bodies which run forward in one direction one after the other and run back more quickly thereunder. Each step body runs on rollers, of which two may each be driven by a respective electric motor. Each step body includes a device for the supplying of electrical current to the step body. Each step body has at least one sensor for determining spacing from the adjacent step bodies. A control electronic system controls the electric motors in dependence on a signal from the sensors, so that the step bodies run directly one after the other in a person transport region. A respective tipping station for inclining the step bodies is provided at each of the ends of the conveying device. In preferred embodiments the step bodies are directly driven by a friction wheel drive or by means of toothed wheels.
