Russian APC-4 Rail Elastic Clips
APC-4 Rail Elastic Clips
The APC-4 spring is a widely used spring fastener in the railway systems of Russia and the Commonwealth of Independent States. It is a core component of the APC-type railway fastener system, mainly used to fix rails and sleepers, ensuring the stability and safety of the track structure.
APC-4 Clips Structural Design
Double-toe spring: Adopts a double-contact design to provide uniform clamping force and prevent lateral displacement of the rail.
Spring steel material: Usually made of high-strength alloy steel such as 60Si2MnA, which is heat-treated to enhance elasticity and fatigue life.
Anti-corrosion treatment: The surface is treated with electrostatic spraying (Baking Varnish) or galvanizing to adapt to harsh climatic conditions.
APC-4 Clips Advantages
High elasticity: Adapts to dynamic loads and reduces track geometric deformation.
Corrosion resistance: Surface treatment extends service life, suitable for humid, saline-alkali environments.
Convenient maintenance: Modular design enables easy replacement and reduces maintenance costs.
Russian APC-4 Rail Elastic Clips Main Application Scenarios
(1) Ordinary railway trunk lines
Suitable for passenger and freight lines (speed ≤ 160 km/h), ensuring rail stability and preventing track deformation.
(2) Heavy-haul railways
Used in coal and ore transportation lines (axle load ≥ 25 tons), with strong anti-fatigue performance, reducing maintenance needs.
(3) Low-temperature and frigid regions
Extremely cold environments such as Siberia and the Far East (-60℃), the material has undergone special treatment to avoid low-temperature brittle fracture.
(4) Electrified railways
Matched with insulated gauge blocks to prevent short circuits in track circuits, suitable for electrified sections.
