Pandrol SKL is a resilient, screwed-direct fastening for concrete sleepers. Simple, reliable and safe, it is a proven solution for ballasted track in many countries.
The rail seat assembly is typically made up of two tension clamps (SKL clips) on top of angled guide plates each side of the rail. The guide plates are located in recesses on the concrete surface, securing the rail horizontally and transferring lateral loading to the sleeper. A pad under the rail provides a layer to attenuate impact and electrical resistance. Everything is held down with screws in concrete dowel inserts.
Custom configurations are possible, for example for dual gauge and turnout sleepers. Theft-resistant screw heads are also available.
