What is a spring clip?
A rail spring clip is a vital, elastic metal fastener, usually made from forged spring steel, used in railway systems to firmly attach steel rails to sleepers (ties) and baseplates, preventing rail movement (vertical/horizontal), maintaining gauge, absorbing vibrations, and ensuring track stability and safety for trains.
Key Functions
Secures Rails: Clamps rails tightly to sleepers, stopping them from shifting.
Maintains Gauge: Keeps the correct distance (gauge) between rails.
Provides Elasticity: Absorbs shocks and vibrations from passing trains, reducing stress on the track structure.
Ensures Stability: Transfers vehicle loads and prevents rail distortion (bending, warping).
Types of rail tension clip
Rail tension clips, or elastic rail clips, secure rails to sleepers, with common types including E-type (E1609, E1809), known for durability; SKL clips (SKL1, SKL12, SKL14), often used in heavy-haul; Nabla clips, offering robust fastening; and specialized clips like Deenik, Crane Rail clips, and Russian clips, each tailored for specific track needs, all made from high-strength spring steel to absorb vibrations and maintain gauge.
- SKL Rail Clips
The SKl rail clips boast a design that guarantees a secure grip and are commonly employed in locations demanding heightened stability, like bends and junctions.
- KPO Rail Clips
Rail clips from KPO provide an efficient method for fastening rail tracks securely in place with ease of installation and upkeep for consistent performance in traditional railway environments.
- Deenik Rail Clips
Deenk rail clips stand out for their design enabling fast installation while maintaining durability intact commonly applied in scenarios requiring swift track setup or maintenance work.
- PR Rail Clips
Rail clips with a tensioned design are often employed in heavy haul railway systems to ensure track alignment remains stable even with varying loads present.
- Nabla Rail Clips
Rail clips from Nabla offer a deal of flexibility along with a powerful grip force enabling them to adjust to slight shifts in the track while ensuring a firm hold, in place.
