FIELD: transportation.
SUBSTANCE: method of suspending supply lines of vehicles between line supports on a railway track consists in that a self-centering system is used. The self-centering system has an internal and the external base, on which internal rotation rollers or sprockets are fixed. The number of rollers on each base is not less than three, the rollers of the external base are outside the volume V, in which the rollers of the internal base are located. The rollers of the external and the internal bases are connected in series with each other by a closed cable, chain, or belt. When the cable, the chain, or the belt is offset along its perimeter, the rotation direction of the rollers or the sprockets of the internal base is opposite to the rotation direction of the rollers or the sprockets of the external base. The number of rollers on the internal base is made odd, for example 3. A pair of rollers is connected directly by a cable section with a tension spring connected in series and arranged on top of masts.
EFFECT: reducing the load on the masts and the possibility of increasing the distance between the masts.
