Abstract
The present application shows a trolley system for providing electrical power to a vehicle, the trolley system comprising: a trolley line that is at least one out of: a flexible structure to be loosely positioned on a ground surface; and a sealed structure with an insulating housing comprising a sealing arrangement for sealing an opening extending along the trolley line, and a current collector assembly mounted on the vehicle for establishing a sliding electrical contact with a conductor of the trolley line.
Claims22
A trolley system for providing electrical power to a vehicle, the trolley system comprising:
- a trolley line comprising an insulating housing enclosing a conductor, wherein the trolley line is:
- a flexible structure to be loosely positioned on a ground surface;
- and
- a current collector assembly mounted on the vehicle for establishing a sliding electrical contact with the conductor of the trolley line,
- wherein the trolley system is configured such that the current collector assembly raises the trolley line from the ground surface for establishing the sliding electrical contact.
A trolley line for providing electrical power to a vehicle, the trolley line comprising an insulating housing enclosing a conductor, the trolley line being a flexible structure to be loosely positioned on a ground surface and configured to be raised from the ground surface by a current collector assembly for establishing a sliding electrical contact with the conductor.
A method of providing electrical power to a vehicle, the method comprising:
- engaging with a current collector assembly of the vehicle a trolley line that is positioned on a ground surface;
- travelling the vehicle along the trolley line, with the current collector assembly raising a section of the trolley line from the ground surface, and
- the current collector assembly establishing a sliding electrical contact with a conductor of the trolley line, the sliding electrical contact being established in the section of the trolley line raised from the ground surface.
