System W 14
Rail fastening systems for concrete sleepers;)
All the fastening components can be manually or automatically pre-assembled in the sleeper factory. The rail is applied at the construction site. Fastening components can be lost neither during transport nor during track laying.
Assembly
The sleeper screw is loosened by 2-3 turns. The tension clamp is pushed on the rail foot and tightened with torque of approx. 250 Nm. A simple work step which requires no special training. Assembly can be carried out using simple commercially available screwing machines or automatic screwing aggregates.
Exchangeability
All components are exchangeable.
Protection against tilting
Any uplifting or tilting of the rail which occurs during tamping of the track or when running through narrow track curves is absorbed by the middle bend after it has overcome the small air gap (between the middle bend of the tensioning clamp and rail base). Permanent deformation of the outer spring arms is therefore excluded.
Different rail sections on the same sleeper
Different rail sections, e.g. UIC 60, UIC 54 and S 49, can be used on the same sleeper with the same track gauge through simple exchange of the angled guide plates.
Track adjustment
A track adjustment of ± 10 mm in steps of 2.5 millimetres is available as standard.
Electrical insulation
The rail fastening system W 14 is completely electrically insulated. No additional insulating components are required between the clamping element and the rail base.
Track maintenance
The Vossloh rail fastening system requires no regular maintenance.
Neutralisation
No fastening elements have to be removed from the sleeper with continuous welding of the rail (CWR). The sleeper screws merely have to be loosened but not disassembled.
Height adjustment
The Vossloh rail fastening system W 14 can be adjusted in height by using height regulation plates. This is also referred to as anti-frost wedge fastening in many countries.
