The Vossloh SKL-12 fasteners are ballastless railroad fasteners and are separate fasteners for sleeper track panels without concrete shoulders. Its main structural features are as follows:

  1. Separate screw holes are respectively arranged at both ends of the ribbed substrate, and are connected with the sleeper/track plate by ballast bolts.
  2. A T-bolt insertion seat and a rail shoulder are provided on the ribbed substrate, and the elastic rail clip is fastened by tightening the nut of the T-bolt.
  3. Horizontal lateral adjustments are made using eccentric tapers of different sizes.
  4. The height of the steel rail can be adjusted by inserting the heightening rail pad.
