Elastic Rail Fastening System SKL

Elastic rail fastening plates with SKL rail clamps. Fastening on concrete bearers in ballast track.

Elastic rail fastening plates with SKL rail clamps

Ripped baseplates, “Skl” tension clamps, rail pads and under baseplate pads are used to fasten turnout parts on concrete bearers. The tension clamps ensure a permanently elastic clamping. The creep resistance and twisting resistance achieved meet the requirements placed on a continuously welded track. The baseplates are mounted on the concrete bearers by four coach screws.

Technical description:

  • Meets EN13481 standard for fastening categories A, B, C, D, E
  • Pre-assembly possible
  • Spring force about 12 kN/clamp

Benefits:

  • Permanently elastic fastening
  • Good creep- and torsion resistance for use in the continuously welded track
  • High tilting stability by middle bend
  • Long service life
  • Low space required
  • Baseplate fastening can be selected, e.g.: coach screws, push-through bolts, angled guide plates
  • The stiffness of the elastic rail pads can be chosen
  • Delivered with or without corrosion protection according to environmental conditions

Elastic rail fastening

The proven plate superstructure with Skl tension clamps ensures a permanent and secure fastening on bearers in ballast track. The tension clamps can be used with or without elastic pads between the turnout components and the plates. The defined mounting position ensures the full tensioning force of the tension clamps for different rail profiles and for pads of different sizes. A plastic deformation of the spring arms is not possible. The tension clamp is fastened on the ribbed baseplate with T-bolt, washer and nut. At the beginning of the tension, both torsion spring arms rest on the rail foot. When the T-bolt is tightened, the middle bend is lead to the rail foot. The optimal mounting condition is reached when the middle bend is close to the rail foot.

Material:

  • Plate: Structural steel / GJS ductile iron / Cast steel
  • Tension clamp: Spring steel
  • Rail pads / Under baseplate pads: according to requirements
  • Corrosion protection: according to requirements

Highly-elastic rail fastening plates with SKL - Fastening for ballastless track

Plates, highly-elastic plate pads as well as “Skl” rail clamps are used to attach turnout parts on a ballastless tracks. The rail clamps ensure a permanent resilient tension. The creep resistance and twisting resistance achieved meet the requirements placed on a continuously welded track. The plates are mounted on the base plate via four or two anchors and pre-tensioned coil springs. Rigidity range 15 - 100 kN/mm. 

Technical description:

  • Meets EN13481 standard for fastening categories A, B, C, D
  • Pre-assembly possible
  • Spring force about 12 kN/clamp

Benefits:

  • Continuously elastic mounting
  • Reduction of ripple and slip wave formation
  • Low maintenance required
  • Long service life
  • Plate fastening can be selected, e.g.: Anchor bolts, screw anchor
  • Height and lateral adjustability possible
  • Top down / bottom up installation is possible
  • Delivered with or without corrosion protection according to environmental conditions

Highly-elastic rail fastening

The proven plate superstructure with, for example, 4 anchor bolts M27 / 2 anchor bolts M33 and Skl rail clamps ensures a permanent and secure mounting on a ballastless trackway in local transport. The dynamic forces of the railway traffic are dissipated into the ground by the elastic components of the fastening. The plate with the rail clamp fastening allows for a uniform deflection and limits the tilting of the rail. The elasticity of the components is adjusted to the axle loads and the driving speeds with the aim of achieving the most uniform deflection of the rails and sleeper components. The elasticity reduces the wheel contact forces and therefore the wear on the track, the substructure and the vehicles as well as the resulting airborne and structure-borne noise.

Material:

  • Plate: Structural steel / GJS ductile iron / cast steel
  • Rail clamp: Spring steel
  • Intermediate rail plates / plate pads: according to requirements
  • Corrosion protection: according to requirements

 

Cooperation with Getzner Werkstoffe

voestalpine and Getzner Werkstoffe, the world’s leading specialist for vibration protection, founded a worldwide cooperation for elastic solutions in the railway sector. The cooperation agreement includes the development, manufacture, and marketing of vibration isolating products and systems to improve the quality of railway tracks.

The integration of elastic solutions in the railway superstructure protects against vibration and reduces track stress.
