Abstract: A non-rail-bound vehicle, in particular a truck, includes a current collector for supplying electric energy from a two-pole overhead conductor. A rocker can be vertically lifted or lowered by a rocking movement of a support extension arm about horizontal tilting axes of lower hinge assemblies and can be laterally displaced by a tilting movement of a support extension arm about vertical pivot axes of the lower hinge assemblies. The lower hinge assemblies are supported on a lifting device which is connected to a vehicle frame of the vehicle and through which the current collector can be vertically moved between a lower parked position and an upper operating position. In this manner, overhead conductors with an extended height range can be contacted without the current collector influencing the entire length of the vehicle.

Abstract: A trolleybus current collector system which enables trolleybuses to pass or overtake one another while still remaining on the same one way supply line. The trolleybus current collector system described herein comprises a trolley pole, which is attached movably with its bottom part to the trolleybus, while its top part is connected to the outer end, with respect to the direction of driving, of an insulating carrier, onto which there are arranged current collector slide blocks. The pole is connected to the carrier by means of a compression body. The outer current collector slide block is mounted rigidly to the carrier. The inner current collector slide block is mounted movably in longitudinal direction with respect to the carrier. To each current collector slide block there is mounted, by means of respective internally diagonal deflectors, a current-carrying bridge. The compression body is fastened to pole parallel to the supply line.
