SKL Clip Models & Specifications
SKL clips are differentiated by their type number and wire diameter, which determine their clamping force and the specific rail section they are designed to secure.
| Model / Type Number | Wire Diameter (mm) | Applicable Rail Type | Key Characteristics & Application |
|---|---|---|---|
| SKL 1 | 16 | S49 / UIC54 / 50 kg/m | Standard duty clip for mainline applications. |
| SKL 3 | 18 | UIC60 / 60 kg/m | Heavy-duty. Provides higher clamping force for high-stress sections like high-speed or heavy-haul lines. |
| SKL 4 | 16 | R65 (Crane Rail) | Designed for crane rails and other special rail profiles. |
| SKL 12 | 13 | Light Rail / Tram | Light-duty clip for tram systems and very light rail. |
Main Types and Specifications
- SKL1: The diameter is 13 mm, the weight is 0.48 kg, the hardness is HRC 42 - 47, and the toe load is 8.0 - 12 kN.
- SKL3: The diameter is 13 mm, and the weight is 0.48 kg.
- SKL14: The diameter is 13 mm, the weight is 0.53 kg, the hardness is HRC 42 - 47. When the clip spring deflection reaches 9.1 mm and the swing deflection is 1.42 mm, the fatigue life can reach 5 million cycles without breaking.
