Cold joints straightening unit ÓÏÑÕ-01
Description
The cold joints straightening unit (ÓÏÑÕ-01) is designed for straightening cold rail joints to meet the required geometry of the rolling surface and of the rail head. The unit straightens the rail in horizontal and vertical planes along standard length of 1300 mm, checking rail bending along 750 mm length by laser sensors.
The unit can pass through insulating rail joints with combined metal-composite fishplates.
The unit is used in moderately-cold conditions, location category 4 as per GOST 15150-69.
