FIELD: pipeline transportation.
SUBSTANCE: support-centering device contains a U-shaped bracket, in which a sliding support is fixed on the central shelf along the axis. The side shelves of the bracket are made in two stages along the length. On each of the two steps of greater height, one spring is fixed at one end. At the other end of each of the springs, an eyelet is rigidly fixed, with the ability to move together with the spring in a vertical plane. Sliding bearings are installed in both eyelets, in the central holes of which there is a shaft on which the rolling support is fixed.
EFFECT: improving the manufacturability and reliability of the process of constructing pipeline crossings.
