REFURBISHMENT SERVICE FOR LEAF SPRINGS
Trapezoidal springs and the modern parabolic springs, made by Axtone, are well proven spring elements for freight wagons all over Europe and beyond – in many dimensions and special designs!
Refurbishment is not a simple assembly process with visual checking of broken leafs and replacement of that.
It is an essential aspect that the leafs will be heat treated after the straightening. This neutralizes the stresses of the straightening process. After the process the original characteristics of the springs are renewed.
