Benefits for Manufacturing, Installation and Operation

  • No cracking in sleepers caused by tension in dowel hole
  • No pre-stressing loss caused by "creeping in dowels"
  • Uniform tension force on account of long lever arms (also see Pandrol)
  • Dynamic amplitudes up to 3.0 mm possible (currently 2.8 mm)
  • Simple handling / Concrete is poured via plastic ring in sleeper factory
  • Simple clip-ons without pre-loading of spring
  • Over tightening is prevented
  • No risk of insufficient tightening
  • Tension easily recognizable by visual inspection
  • Constant tension force
  • No drainage openings required
  • Assembly on track in one step instead of three
