The SL1 rail fastening system is an elastic fastening solution designed to secure rails to concrete sleepers, maintaining track gauge, absorbing impact vibrations, and preventing longitudinal and lateral rail movement under heavy traffic.
This system is suitable for heavy-haul freight lines, conventional passenger lines, and complex track geometries with a minimum curve radius of 150 meters. It operates reliably under conditions with maximum axle loads of up to 30 tons and train speeds of up to 250 km/h.
Main Components of SL1 rail fasteners system:
- 2 Tension clamps: Provide elastic clamping force to hold the rail firmly against the base.
- 2 Angle guide plates: Position the rail correctly and transfer lateral forces to the sleeper.
- 2 Sleeper screws with washers: Anchor the assembly into the sleeper inserts.
- 2 Plastic thread inserts: Embedded in the concrete sleeper to receive the sleeper screws.
- 1 Rail pad: Placed beneath the rail foot to reduce vibration, dampen shock, and provide electrical insulation.
