What are the specifications of Pandrol e-clips?
Pandrol e-clips are railway fastening systems made from high-strength spring steel, available in different diameters (e.g., Ø18 for tram and Ø20 for train). Key specifications include a hardness of 44-48 HRC, static stiffness of over 50 kN/mm, and a clamping force greater than 16 kN. The e-clip system includes the clips, shoulders, pads, and insulators, designed for use on ballasted track with concrete or wooden sleepers.
Clip specifications
- Material: Spring steel, with common types including 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7.
- Diameter: Ø18 mm for tram applications and Ø20 mm for train track applications.
- Hardness: 44 to 48 HRC.
- Fatigue life: Dependent on diameter; for example, a Ø20 mm clip can have a fatigue life of 5 million cycles without breaking.
