YLS-900 Hydraulic Rail Tensor

It's suitable for 75kg/m and 60kg/m type rail stress relief and seamless long rail relaying.  While operatingin the feld at a certain temperature range being lower than the rail locking temperature, by employingthis machine, the length of a rail with zero-stress can be forced to stretch to a length at locking tem-perature, then re-lock the rail.
