Significantly increasing passenger numbers and a consistent shift of freight traffic to environmentally friendly rail will inevitably lead to acute strains on the rail infrastructure. In order to make the rail infrastructure more durable and resistant, Vossloh has introduced its new M-Generation tension clamps.

With the development of the M-Generation, Vossloh AG is presenting rail customers worldwide with two major innovations. Firstly, guaranteed safety on all tracks despite increasing demands and greater load levels, and secondly, an improved carbon footprint over the entire service life.

Compact in design, the outwardly curved spring arms are the most striking feature of the new tension clamps. Their geometry, which resembles an ‘M’ in cursive, provides both a larger contact area to the rail base and reduced contact stress. Increased fatigue strengths are achieved by accommodating the three dimensional stress directions in a unique geometry. 

Vossloh points out that the high natural frequency – two to three times higher than previous tension clamps in the respective application area – strengthens the robustness of the new type of tension clamps against external influences. This lowers lifecycle costs on a comparative basis and allows the use of more elastic rail fastening systems to further reduce vibrations. This is because, thanks to their excellent load and deflection characteristics, M-Generation tension clamps maintain rail stability over a long period of time, even under extreme conditions.

Vossloh has also enhanced the material used, with a micro-steel alloy optimising the tried and tested properties. A low stress bending process and an improved hardening process are used in production, so that CO₂ emissions can be significantly reduced in conjunction with the compact product design. Ready for use in all areas of application, the clamp is available in M3, M7 and M9 variants.
