This machine can not only be used for repairing the broken rails of the seamless track, but also can be used for the stress relief of the seamless track and the adjustment of the track seam in sections of the ordinary track, and is suitable for various rail types. The use of this product can change the traditional method of repairing broken rails, that is, adopting rewelding without inserting short rails, which saves time and effort, expands the operating rail temperature range, and prevents the actual lock rail temperature from changing.
