The Rail Stressor TR75 has been designed for the stress relief or replacement of continuous welded rails (CWRs). It is used during maintenance works to stretch long welded rails before aluminothermic welding and to secure the tensioned rail while cutting. It is capable of joining and maintaining a constant gap between the two rail ends.
Fitted with a hydraulic power unit and an integrated hand pump, the Rail Stressor TR75 is flexible enough for use in any rail setting, including tunnels and urban areas. It has gained SNCF homologation (Nr DEO 19280).
