{{ Reparatur }}

Additional to own brand production, RFT is specialized in repairing storm brakes / rail clamps of other brands due to in-house production flexibility.

Rail clamps show wear due to the fact that they are in use over many years, which means they no longer have the neccessary safety levels required.

  • Functional analysis oft he rail clamp / storm brake
  • Renewal of the clamping jaws
  • Renewal of the bushes
  • Renewal of the axis
  • Renewal of the wheels
  • New painting
  • In case of extreme steel wear the construction will be overhauled and restored into the original condition
  • High-grade 2-component paint

In specific situations, the RFT can provide a storm brake as a ring exchange.Therefore the Intralogistics and safety operates smoothly and is undisturbed.

Please indicate your existing rail clamp type.
