A vehicle-related arm-shaped contact means comprising cleaning means a system ("S") for propelling an electrically propellable vehicle by one or several batteries or a set of batteries ("II", B) along a roadway comprising roadway sections (2a1, 2a), the system comprising: "a" a plurality of roadway portions (2a1, 2a) for subdividing the roadway into said roadway sections, wherein each one of the roadway sections comprises one or more elongated tracks (51, 52) having conductors (4a, 4b) introduced therein adapted to be supplied with current and put under voltage, and being connectable via a switch to one or more vehicle-external power sources ("III"), for thereby enabling charging of said set of batteries ("II", B) related to the vehicle arranged primarily for driving the vehicle along the roadway and the roadway sections (2a1, 2a), and "b" one or more vehicles propellable by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit (100, "R1 ") adapted for a necessary distribution of power, adapted for creating required power and/or speed control, wherein said vehicle is, on its underneath side, adapted to be provided with said contact means in an up and down and sideways, in relation to the direction of transportation of the vehicle, displaceable manner, and with wherein said elongated track or tracks and the conductors (4a, 4b) extend along the roadway and the roadway sections (2a1, 2a) and wherein a vehicle-related control equipment (100, 10) is adapted to co-operate with and create an adaptation of the contact means so as at least to offer a mechanical and electrical contact with said conductors (4a, 4b), wherein the contact means is formed as current collectors adapted for mechanical and electrical cooperation with respective ones of the conductors (4a, 4b) placed under voltage, wherein the cleaning means is oriented in the direction of transportation of the vehicle and comprises a forwardly directed edge portion, said edge portion comprising a point, which is connectable to to the track and the conductors, characterized in that the cleaning means is configured to rotate with the edge portion moving in an opposite direction to said direction of transportation to lift from the track when the means collides with a stationary object on said track by being rotatably fastened in its upper area around a horizontally oriented axis of rotation, wherein said axis of rotation is movably disposed in a vertical direction by using a resilient or spring shaped means. "a" a plurality of roadway portions (2a1, 2a) for subdividing the roadway into said roadway sections, wherein each one of the roadway sections comprises one or more elongated tracks (51, 52) having conductors (4a, 4b) introduced therein adapted to be supplied with current and put under voltage, and being connectable via a switch to one or more vehicle-external power sources ("III"), for thereby enabling charging of said set of batteries ("II", B) related to the vehicle arranged primarily for driving the vehicle along the roadway and the roadway sections (2a1, 2a), and "b" one or more vehicles propellable by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit (100, "R1 ") adapted for a necessary distribution of power, adapted for creating required power and/or speed control, wherein said vehicle is, on its underneath side, adapted to be provided with said contact means in an up and down and sideways, in relation to the direction of transportation of the vehicle, displaceable manner, and with wherein said elongated track or tracks and the conductors (4a, 4b) extend along the roadway and the roadway sections (2a1, 2a) and wherein a vehicle-related control equipment (100, 10) is adapted to co-operate with and create an adaptation of the contact means so as at least to offer a mechanical and electrical contact with said conductors (4a, 4b), wherein the contact means is formed as current collectors adapted for mechanical and electrical cooperation with respective ones of the conductors (4a, 4b) placed under voltage, wherein the cleaning means is oriented in the direction of transportation of the vehicle and comprises a forwardly directed edge portion, said edge portion comprising a point, which is connectable to to the track and the conductors, characterized in that the cleaning means is configured to rotate with the edge portion moving in an opposite direction to said direction of transportation to lift from the track when the means collides with a stationary object on said track by being rotatably fastened in its upper area around a horizontally oriented axis of rotation, wherein said axis of rotation is movably disposed in a vertical direction by using a resilient or spring shaped means.
