Abstract: The invention relates to a shoe (10) on an electrical power supply track for an electric railway vehicle, the shoe (10) comprising: a power supply flange (12) movable between a retracted position and a deployed position; an actuator (11) able to move the flange between the retracted and deployed positions; and a mechanical system (13) connecting the flange to the actuator; characterized in that the actuator (11): has a movement speed such that it is able to move the flange (12) between its retracted and deployed positions in a time period shorter than or equal to 1 second, and preferably shorter than or equal to 0.5 seconds; and has a number of operating cycles before failure greater than or equal to 2,500,000.

Abstract: A cantilever supports a catenary to supply energy to a vehicle. The cantilever includes a cross-member adapted to be attached to a support structure, the cross-member extending along a longitudinal axis (X-X), and at least one attachment connected to the cross-member. The cross-member includes an outer surface, the outer surface including at least a first side having a non-circular shape in a section plane (II-II) that is orthogonal to the longitudinal axis (X-X). The attachment includes at least one collar encircling the cross-member, and the collar includes at least one contact face in contact with the at least first side.
