Abstract

A current contact line arrangement includes a plurality of energy and control current contact lines for engagement with current collectors of a movable energy consumer such as a crane, trolley carriage or the like which is not intended to pass beyond a predetermined point and is characterized by the fact that at least one of the energy or control current contact lines (5) is covered by an insulator (9) which is longer than the brake path of the movable energy consumer.
