rail stress relief and seamless long rail relaying
May 06, 2026| The machine is suitable for rail stress relief and seamless long rail relaying. While operating in the field at a certain temperature range being lower than the rail locking temperature, by employing this machine, the length of a rail with zero-stress can be forced to stretch to a length at locking temperature, then re-lock the rail.
Compared with the similar products, it possesses features of unique design, light weight, simple & convenient manipulation and powerful rail pulling force.
