Trolley pole – Wikipedia

Origins. When the bow collector was first conceived by German inventor Ernst Werner von Siemens in the late 1880s, American inventor Frank J. Sprague of Virginia had just patented his trolley pole system of current collection from an overhead wire.To avoid contravening this patent, the Siemens company was forced to design its own, unique form of current collection, namely the bow collector.

The current collection device (trolley pole or pantograph) presses against the underside of the lowest wire of an overhead line system, which is called a contact wire. The current collectors are electrically conductive, and allow current to the train or tram, and back to the feeder station via the steel wheels and one or both running rails of the track.

70A Current Collector Trolley for fully insulated body with Copper Collector Shoes for DSL Enclosed type Busbar Wheels are equipped with ball bearings. For current rating over 70A, connect more trolleys on parallel. Replacement Current Collectors are supplied for Giovenzana, GG, TR65, TR85 Conductor Rails.

The pantograph was an improvement on the simple trolley pole, which prevailed up to that time, primarily because the pantograph allows an electric-rail vehicle to travel at much higher speeds without losing contact with the overhead lines, e.g. due to dewirement of the trolley pole. Notwithstanding this, trolley pole current collection was used
