An electric railway system’s rail trolley pole, sometimes referred to as a trolley or bow collector, is a part used to transmit electricity from an overhead wire to an electric vehicle (such a tram or streetcar).
It acts as an interface between the electrical equipment on board the vehicle and the overhead wire, allowing power to flow for propulsion and other purposes.
Typically, steel or aluminium, two lightweight yet durable materials, are used to create the tram pole. It is connected to the electrical system and put on the roof of the electric car.
The pole features a sliding or swivelling mechanism that enables it to easily travel along the above wire as it stretches vertically upward.
A metal shoe or collector head that makes contact with the overhead wire is located at the top of the tram pole. A rolling or sliding contact shoe that keeps consistent contact with the wire on the collector head is often included, guaranteeing a solid electrical connection.
To reduce wear and preserve good electrical conductivity, this contact shoe’s composition may include metal or carbon. The tram pole slides or pivots along the overhead wire, following the course of the electric vehicle as it travels down the tracks.
The electric current from the wire can enter the vehicle’s electrical system because to this constant contact between the collector head and the wire. The electrical power is then used for a variety of tasks, including propulsion.
The Global Rail Trolley pole Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Launched by Wabtec is a brand-new tram pole. The tram poles function with all global network architectures. Collectors can be used to charge batteries while in motion or to collect conventional electricity from the traction network.
Some of the main advantages are fully standardized and catalogue items that are interoperable with all global network systems.
These are very useful when an overhead wire can waver or veer off course because the sliding or swivelling mechanism enables the pole to adjust to the wire’s movement.
