The SKL is a robust, direct-screw fastening system designed for concrete sleepers. It's simple, dependable, and safe, having been validated as a reliable solution for ballasted tracks across numerous countries.

The rail seat assembly consists of two tension clamps (SKL clips) situated on top of angled guide plates. These guide plates fit into recesses on the concrete surface, securing the rail horizontally and transmitting lateral loads to the sleeper. A pad under the rail provides cushioning for impact absorption and electrical insulation.

Product Advantages

Gauge Adjustment: Simple component swapping removes the need for different sleepers during gauge widening.
Reduced Handling: Captive fastening reduces the risk of losing components, saving time and costs.
Replaceable Components: All parts, including concrete dowels, are replaceable to limit maintenance expenses.
Variable Clamping Force: Longitudinal restraint can be adjusted for specific track areas.
Stiffness Regulation: Overall track stiffness targets can be met even as conditions change over time.
Overturning Stop: Keeps the rail secure and protects clips from overstretching or failure.
