Vossloh Fastening Systems - Track Fastening Systems

Vossloh Fastening Systems is a global leader in the production of track fastening systems. High-speed, heavy-haul, urban transport or standard lines are all equipped with our cutting-edge products. Standing for extreme resilience, top quality, maximum safety and cost-effectiveness, our solutions make a key contribution to keeping people and freight mobile.

High-speed rail fastening systems

The Skl 21 high-speed tension clamp permanently clamps the rail to the concrete sleeper by means of the outer spring arms.

This high-speed tension clamp has fatigue strength of 2.5mm for five million load cycles. Therefore it is possible to use rail pads with a static stiffness greater or equal to 30kN/mm.

During tamping and lining of the rails or when passing through tight curves, a lift or tilt of the rail is compensated by the middle bend of the tension clamp, which projects above the rail foot (steep curve of the spring characteristic). Overloading of the spring arms and consequently plastic deformation is thereby excluded.

The highly elastic rail pad is protected from over-stress by means of a small nose in the front of the angled guide plate, which provides additional protection against rail tilting.

Rail fastening system for slab tracks

Slab tracks meet all the requirements for combined high speed and heavy load traffic.

The 300 rail fastening system for slab tracks, which can be pre-assembled, is suitable for all methods of slab track installation. The highly elastic intermediate plate substitutes for the elasticity of the ballast bed. A steel pressure distribution pad, which supports the rail through the interposition of conventional rail pads, is used to improve the load distribution on the intermediate plate.

The rail is held laterally in position by plastic, angled guide plates. The rail is permanently tensioned by spring-actuation as a result of the long elastic spring deflection of the Skl 15 tension clamp.

The rail fastening system 300 can be adjusted by 30mm in height and by 20mm in track gauge.
