An electrical brush contact apparatus for conveying electrical power from a vehicle power source to the wheels of vehicles having dual-tandem pairs of wheels includes a brush ring positioned at the juncture between the inner and outer rims of the front pair of dual-tandem vehicle wheels and the inner and outer rims of the rear pair of dual-tandem vehicle wheels. Each of the brush rings is electrically insulated from the rims with which it is associated by a flat insulating member or an insulating extrusion. Each pair of insulating extrusions and brush ring are coupled for rotation in concert with the wheels of the vehicle. Front and rear support members having idler pulleys thereon are suspended between the inner and outer pair of dual wheels and between the front and rear pair of tandem wheels. A belt, coupled between each one of the brush rings and an adjacent one of the idler pulleys, is driven by the brush ring. A central turnbuckle is employed to adjustably couple the front and rear support members, thereby providing adjustment for the tension of the belts driven by the brush rings. Electrical power from the vehicle is connected to the front and rear support members and thence to the brush rings by way of brushes that are connected to the front and rear support members and that are also in electrical contact with the brush rings. The electrical power conveyed to the rotating brush rings may then be connected to lighting systems, sensors, etc.
