Abstract
A device for receiving, from a fixed electric connection, adapting to length, and holding conductors for the electric current supply of movable consumers. The electric conductors are moved by way of at least one carriage in conformity with the movement of the consumer along a guiding path, especially for rotatable superstructures. The carriage which may be similar to a trolley is equipped with at least one spool box having at least one rotatably mounted and easily exchangeable winding mandrel which is provided with a slot extending transverse to the longitudinal axis of the mandrel for passing therethrough a flat cable adapted to wind itself up. When the pre-load of the flat cable is reduced, a tensioning force can be exerted by way of remote control upon the winding mandrel. The consumer connection is provided with entraining mechanism which serves as cable carrier and is guided in the manner of a carriage or trolley. The spool box is provided with a plurality of guiding rollers for the flat cable, and the entraining mechanism has guiding strips bent off at the ends thereof while outside the spool box and the entraining mechanism there is provided a roller path serving as guiding and holding portion for the flat cable sections between the fixed electric connection and the spool box and between the latter and the entraining mechanism.
