W30 Fastening System
The W30 rail fastening system is widely used on ballasted tracks and concrete sleepers. It operates reliably with minimal wear and requires minimal maintenance.
Basic Parameters
- Axle load: ≤ 35 t
- Speed: ≤ 160 km/h
- Curve radius: ≥ 400 m
- Height adjustment: optional
- Gauge adjustment: ± 10 mm
Its rail clips can withstand high loads, dynamic fatigue, and creep resistance, offering a highly elastic solution for conventional and heavy-duty rails. Its components are easy to handle and replace, which reduces downtime and maintenance costs, making it a cost-effective solution for railway operators.
We use TPU material for the rail pad, which can endure harsh weather conditions, adapting to a wide temperature range from -60°C to 50°C. This makes it an ideal material for coping with extreme temperature fluctuations. Even under extreme weather conditions and high atmospheric humidity, it ensures a safe ride every time.
The complete W30 fastening system for each sleeper consists of the following components
- 4 pcs Screw spike Ss35-161
- 4 pcs Flat washer UIs7
- 4 pcs Rail clip SKL30
- 4pcs Guide plate Wfp30K-12hh
- 4 pcs Plastic dowel SDU25
- 2 pcs Rail pad Zw148/175/7
