ABSTRACT:
An overhead plural conductor trolley rail and flying pickup for supplying electrical power to a vehicle includes a plastic extrusion fastened to an overhead structure housing parallel flat conductors, the exposed underside of each of the conductors being engaged by shoes carried on vehicle supported trolley units. At one end of the rail a guide structure for the trolley includes a central, side skirted or inverted channel shaped portion, flanked at either end by oppositely extending side-skirted ramps each inclined upwardly from the central portion. The approach ramp also diverges horizontally outwardly of the rail support. To accurately engage the trolley carried shoes with the rails, the operator need only insure that the trolley enters the divergent portion of the guide at its widest open end. When the trolley is advanced to the central portion of the guide by forward movement of the vehicle the shoes will be automatically horizontally aligned but vertically spaced from the rails so that further inward movement of the trolley along the inner upwardly inclined exit section insures that the shoes will rise accurately into engagement with the rails. The trolley units are biased vertically upwardly toward the guides and the rails.
