<p>Contact means (4) related to a vehicle are adapted to comprise an elongated arm (50), one end portion (50a) of which is rotatably attached to the underside (bottom)of the vehicle (1) and the other end portion (50b) of which is adapted to support said contact means (4). One or more sensors (151a, 151b) are disposed at the vehicle (1) and are intended to be able to sense the presence of and the orientation of a track or groove (51) and transfer sensed information to a power control circuit(100), which is adapted to comprise a control circuit (100b), which when sensing the existence of and a sensed orientation of at rack or groove (51), within a covered and restricted area, is to be adapted to actuate means (7) adapted to a sidewise movement and/or a lowering (or raising) movement at the contact means (4).</p> |
