Electric track vehicle system

Vehicles in an ETV system transport payloads up to 50 kg both vertical and horizontal in buildings and manufacturing plants.

ETV systems were primarily put on the market in the sixties by German company Telelift.

[1][better source needed] Later additional companies like Siemens[2] or Thyssen engaged in this business.

Initially, electric track vehicle systems were designed for documents transport and mail distribution in office buildings and headquarters.

E.g., the ETV system in the Bibliothèque nationale de France in Paris consists of 6.6 km tracks, 151 stations and 300 vehicles.
