art ground conveyor installations are no longer necessary since the rapid stopping mechanisms assume their function the steering mechanism 20 possesses the scanning or feeler head 22 which contains five scanning or feeler elements 36 a central scanning or feeler element 36 1 which is located over the guide track a when traveling straight ahead serves the purpose after turning or deflecting the conveyor car onto the guide track of bringing about resetting of the turning or steering deflection transversely with respect to the conveying direction and to both sides of the central scanning element 36 1 there are located at a slight spacing therefrom the first scanning elements 36 2 activation of the first scanning elements 36 2 bring about only a small steering deflection or turning effect and serves to correct the conveyor car during slight deviations from the guide track at progressively larger spacing there are arranged towards the outside at both sides of the first scanning elements 36 2 the second scanning elements 36 3 which during greater deviations of the conveyor car especially when traveling in curves and at branches come into play and bring about a greater steering deflection the scanning elements 36 are operatively connected with the cam switching mechanism 28 wherein each scanning element has associated therewith a cam disk 38 the switching cams 40 of which cooperate with switching elements 42 the cam switching mechanism 28 is coupled through the intermediary of a toothed belt 44 with a steering drive 46 which is driven from a steering motor 48 likewise through the agency of a toothed belt 50 the steering drive or transmission contains a crank guide drive.
