Device for collapsing bars of trolleybus current collector

摘要

The bars (2) of a trolleybus current collector are hinged to a turntable (11) forming a part of a frame (1). Both a lifting spring (4) and a tilting pressure cylinder (5) are arranged between the frame (1) and bars (2). Said pressure cylinder (5) piston rod is hinged to an arm (3) of the bar (2). Said arm (3) is hinged to the bar (2) with a stop (23) for abutting the end of a corresponding arm (3) by a region if its hinge to said pressure cylinder (5) piston rod.
