Rail vehicles operating in northern climates such as Northern Europe, Canada, and the northern United States face extremely demanding winter conditions. Temperatures can plunge well below –40 °C, snow can accumulate deep inside bogie structures, and salt, moisture, and debris continuously attack exposed mechanical components throughout the winter season. Under these conditions, the shock absorber is working as a safety-critical device that stabilizes the vehicle, protects the bogie, and ensures predictable dynamic behavior year-round.
For rolling-stock manufacturers delivering vehicles to these regions, SV-SHOCKS provides a proven and certified solution: dampers engineered and tested specifically for reliable performance in freezing temperatures and rapidly changing climatic conditions.
Designed and Tested for Extreme Cold
SV-SHOCKS dampers are developed to remain fully functional even in temperatures reaching –60 °C. Our damper testing includes temperature testing up to -60°C. Due to its Northern location, SV-SHOCKS is very familiar with the demanding conditions that shock absorbers face when the weather is freezing cold.
Dampers Protected Against Snow, Ice, Salt, and Debris
- Corrosion-resistant materials and coating
- Mechanical robustness for depris impact
- Solutions for snow and ice accumulation
SV-SHOCKS dampers are built to withstand the harsh environmental stresses of winter rail operations. Corrosion-resistant materials and advanced coatings protect the components from salt spray, moisture, and other contaminants, ensuring long-term structural integrity even in coastal or heavily salted regions. Their reinforced housings and pistons provide the mechanical strength needed to resist impacts from ballast stones, ice, and other debris without performance loss. In addition, the dampers are engineered to function reliably even when snow or ice accumulates in the bogie, maintaining full stroke, preventing blockage, and avoiding stick-slip behavior under frozen conditions.
Reliable Dampers for All Winter Track Conditions
Our dampers are known for delivering stable, predictable performance regardless of load condition, track geometry, or temperature. SV-SHOCKS dampers are optimized for:
- High-speed passenger rail where stability and comfort are essential
- Trams and LRVs exposed to urban salt, snow, and extreme thermal cycling
- Special vehicles operating in remote, high-latitude regions
