Abstract: This invention comprises a detector arrangement, said arrangement is related to a system (“S”), adapted for driving a vehicle (1) driven electrically and by one or several batteries, along a stretch of roadway, comprising “a” one or more over an individual electric motor or motors driveable vehicle (1), and “b” a plurality of road sections (2a1, 2a) subdividing the stretch of the roadway, each one being allotted one or more electric stations (s1, III) for charging the set of batteries (“B”) of the vehicle (1) and/or for supplying the necessary power and energy for driving the vehicle forward. Said vehicle (1) is on its underneath side provided with a displaceably disposed contact means as a current collector (41a, 41b; 42a, 42b), movable up and down and displaceable sideways, counted in the direction of transportation.

Abstract: 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).

Abstract: This invention comprises an arrangement for metal detection and said arrangement is related to a system (“S”) adapted for driving a vehicle (1) electrically and by one or more batteries along a stretch of roadway, comprising “a” one or more over one or more electric motors propellable vehicles (1), with the respective vehicles (1) exhibiting a control circuit (100, “R1”) and “b” a plurality of roadway sections (2a1, 2a) dividing the stretch of roadway, each roadway section being allotted one or more electric stations (“s1, “III”). Said vehicle (1) is on its bottom side provided with a up and down and sideways, counted in the direction of transportation, displaceably positioned contact means or current collector ((4)). Said roadway section (2a1) exhibits, counted in the normal direction of transportation of the vehicle (1), elongated tracks (51) having rails (4a, 4b) positioned below the roadway and being capable of having current supply and being placed under voltage.
