CA 2189409
A current collector (15) is provided for transmitting energy between a contact wire (2) and a motor coach. The current collector (15) comprises at least one collector shoe (1) and a support arm (11) for lifting the collector shoe (1) and for applying a contact force with which the collector shoe (1) lies from below against the contact wire (2) in transmitting energy. The support arm (11) is connected to the motor coach rotatably about a horizontal axis (17) and raisable about said axis (17) by a lifting device (3). The lifting device (3) is associated with a fast actuator (23) which is controlled by a control means (22) in dependence on the signal (20, 21) of at least one displacement sensor, force sensor (18) or acceleration sensor (19) located on the current collector (15) to keep constant the contact force of the collector shoe (1) against the contact wire (2).
