The pantograph intended for picking up the current by a rail-bound traction vehicle, comprises an upper arm (5) whose end comprises at least one support (22). Two pick-up heads (20), provided with friction bands (19) which make the electrical connection with a catenary line (L), are connected to the support (22) by connecting means (23,24,25,28,30) which guide them in their movement transverse to the line and perpendicular to the plane of the track and which are adapted in order that, when one of the heads (20) undergoes a movement relative to the support (22), a force of opposite direction is exerted on the other head (20). <IMAGE> |
