Turnout or crossover piece for electrical pipe systems.

As far as "for contact line systems for electric vehicles jElollen- and (rleitschuh-StromaTDnehmer are used, are to Afczwei- and! crossing points turnouts- Tsezw. Chalking pieces like that to incorporate »that an unhindered passage of the StromaTjnehnierß is possible. As a rule, the current is drawn along the length of the Contact wire in such a way that the contact wire in the role "respectively Grinding piece of the shoe slides. This immediate «contact Tone contact wire and pantograph are called the base run. In the area of the turnout or crossing piece, however, the pantograph runs on the Eänder of the EoIle respectively. on the bar of the contact strip and is guided through a middle bar. This yor ~ gang is called edge or web run. In the latter case, there was a considerable disadvantage in previous designs due to the ! It is a fact that when using gunmetal or malleable cast iron a Considerable weight expenditure and when made of light metal

Yortoil of the "invention basically consists in the fact that the turnout and crossing pieces are extremely light and have a long service life. The strength is significantly increased by an insert, in particular a steel insert", so that the other parts are out of the body thin-walled cast, in particular made of non-ferrous metal cast, or made of pressed material. Because the insert, which also serves as a support surface, is made of hard metal, there is particularly little wear and tear.
