The present disclosure discloses a power-taking device for a rail guide vehicle. The rail guide vehicle includes a chassis travelling mechanism and a loading mechanism including a fixing plate, a power plate, an extension plate and a shifting fork, the fixing plate is fixed to the chassis travelling mechanism, the power plate and the extension plate can be translated, and the shifting fork is coupled to, can be translated in synchronization with, and can be rotated with respect to the extension plate. The power-taking device includes: a first conductive part, fixed to the fixing plate; a second conductive part, fixed to the power plate; and a third conductive part, fixed to the extension plate. When the first, second and third conductive parts are in contact, the power-taking device is turned on.

A current transport mechanism with an elongated, electromechanical base conductor that has an electrically rigidly mechanical plug-in connection device connected thereto in an electrically-rigidly mechanical manner and which, in turn, can be electrically contacted by an electrically-rigidly mechanical mating plug-in connection device.

Electrified roadway systems include a roadway, and vehicles configured to operate on the roadway. The roadway has a base, and two electrically-conductive rails mounted on the base. One of the rails is electrically connected to a source of electric power, and the other rail is electrically connected to an electrical ground. The vehicles include non-electrically-conductive tires, and an electric motor mechanically connected to, and configured to rotate at least one of the tires to propel the vehicle along the roadway. The vehicles draw electric power from the roadway via two electrical pickups that contact the respective rails, and a retracted position at which the pickups are out of contact with the rails. A wear-resistant cover can be positioned on each of the rails. The wear resist covers can have features that maximize the contact area and the contact force between the covers and the rails.

A method and a device test whether there is contact between a current collector and a contact wire of an overhead line. The current collector is located on a motor vehicle driven by an electric motor, and the contact wire extends in a direction of travel. The current collector has two contact regions oriented transversely to the direction of travel which are arranged one behind the other in the direction of travel and on each of which an end contact element is located. A pair of end contact elements located on the same side is connected to a measuring device and an electrical state variable is detected by the measuring device. Subsequently, it is determined in accordance with the detected state variable whether the pair of end contact elements is in contact with the overhead line.
