A current collector (15) is provided for transmitting energy between a contact wire (2) and a motor coach. The current collector comprises at least one collector shoe (1) and a support arm (11) constructed and arranged to lift the collector shoe, and to apply a contact force in which the collector shoe lies below and against the contact wire. The support arm is rotatably connected to the motor coach about a horizontal axis (17) and raiseable about the axis by a lifting device (3). The lifting device includes a fast actuator (23) which is constructed and arranged to be controlled by a control device (22) in dependence on a signal (20, 21) of at least one displacement sensor, force sensor (18), or acceleration sensor (19) located on the current collector to maintain the contact force of the collector shoe against the contact wire.
A current collector for transmitting energy between an energy transmitting contact wire and a motor coach, the current collector comprising at least one collector shoe and a support arm constructed and arranged to lift the collector shoe for applying a contact force between the collector shoe and the contact wire in which the collector shoe lies below and against the contact wire, the support arm being rotatably connected to the motor coach about a horizontal axis and being constructed and arranged to be lifted about said axis by a lifting device, wherein the lifting device has an actuator controlled by a control means, said control means acting in response to a signal emitted by a sensor means positioned on the current collector, the lifting device acting upon the support arm via a traction rope, and wherein the actuator acts upon the traction rope.
