Abstract

Abstract A current supply arrangement for a mobile load device consists of an elongate, flexible, stringlike member of hollow-sectioned profile forming a collection line duct accommodating a flexible conductor of corresponding length and forming a single current supply pole, and a current pickup device comprising a slide carried by the collector line duct and guided in a slot therein, the slide being connected with the load device for traction thereby. A plurality of these single current supply poles are strung in side-by-side parallel relation along a required route to form a multipole current supply unit.
