System for displacement of a current collector relative to the contact wire

摘要

The arrangement has an electrical drive (9) coupled via an actuation element (8) to a pivot shaft (6) of the current pickup (5) pressed against the power wire by spring force. A rapid lowering unit (43) integrated into the actuation element has a biased force storage device (20). The force storage device and electric drive are coupled to a sensor (42) associated with the current pickup.
