Hot joints straightening unit ÓÏÑ-02
Description
The hot joints straightening unit ÓÏÑ-02 is designed for straightening hot welded joints to meet the requirements of the rolling surface and the rail head geometry. The unit straightens the rail in horizontal and vertical planes along standard length of 1 700 mm. The straightness of the welded joint is checked on the rolling surface of the rail head.
The unit can pass through insulated rail joints with combined metal-composite fishplates.
The unit is used in moderately-cold conditions, location category 4 as per GOST 15150-69.
