AboutThe company was established in 1994 and is a production enterprise specializing in the research and development, production, and sales of railway line specific accessories
In the intricate dance of forces that define railway operations—where dynamic loads meet relentless vibration—elasticity is not a luxury, it’s a necessity. Enter the SKL14 Rail Clip, a precision-engineered spring component critical to maintaining constant toe load, ensuring rail stability, and absorbing energy in today’s high-performance track systems.
Why the SKL14 Clip is Non-Negotiable for Track Integrity:
Constant Toe Load Maintenance: Exerts uniform pressure on the rail foot, preventing loosening under vibration or thermal expansion.
Fatigue Resistance: Engineered for 3+ million load cycles, far exceeding conventional clips in high-stress corridors.
Vibration & Impact Absorption: Reduces force transmission to sleepers and ballast, cutting maintenance costs by ≤30%.
Corrosion Defense: Optional advanced coatings (Dacromet®, Geomet®, Zn-Ni) resist salt, abrasion, and chemical exposure.
Quick Installation/Replacement: Designed for efficient maintenance with standard clip applicators.
Engineering Excellence: What Sets the SKL14 Apart
1. Precision Material Science & Manufacturing:
Cold-Formed Spring Steel: High-carbon steel (e.g., 60Si7, EN 10270-1) cold-formed to enhance grain structure and fatigue strength.
Optimized Heat Treatment: Stress-relieving and tempering processes achieve HRC 44–50 hardness for ideal elasticity-to-strength ratio.
Surface Integrity: Shot-peened finish eliminates micro-cracks, boosting fatigue life by ≥25% vs. non-treated alternatives.
