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.
Claims13
In combination a current contact line arrangement for current collectors of a movable electrical vehicle, comprising:
- a plurality of contact lines (5) having faces for engagement with a plurality of current collectors of said movable electric vehicle, said electric vehicle having a braking path distance;
- and
- an insulator (9) for covering at least one of said faces of at least one of said plurality of contact lines (5), said insulator (9) having a length greater than said braking path distance of said electric vehicle, whereby at least one of said plurality of collectors is removed from electrical contact with said at least one of said plurality of contact lines while said at least one of said plurality of collectors is located at said at least one of said faces of said at least one of said plurality of contact lines.
