Grade 4.6: Q235 Grade 5.6: 35# Grade 8.8: 45# |
Plain oiled, black oxide, galvanized, hot dip galvanized, Dacromet and sherardized |
Standard: ISO898-1, UIC864-1 and NF F500-50 |
| Plain washer | Uls7 | Q235 |
Plain oiled, black oxide, galvanized, hot dip galvanized, Dacromet and sherardized |
Standard: EN10025, EN10139 |
| Plastic dowel | For different sizes of screw spike | HDPE, Reinforced Nylon 66 (PA66) | Black, blue, yellow, green or other color | For insert into concrete sleeper |
| Guide plate | UIC54, UIC60, 50kg rail, 60kg rail, and other sizes as ordered | Reinforced Nylon 66 (PA66) | Black, blue, yellow, green or other color | Different designs are available. |
| Rail pad | UIC54,UIC60, and size as ordered | EVA, or rubber | Black, blue, yellow, green or other color | Different designs are available. |
Features:
- Skl 14 R tension clamp with 1.8 mm fatigue strength
- Rail tilting protection by middle bend of the tension clamp and special design of the angled guide plate
- Pre-assembly of all components in the sleeper factory possible
- Reduction of maintenance costs by permanent elastic tensioning of the rail with tension clamps (2 x 12 kN toe load)
- Gauge adjustment ±10 mm in 2.5 mm steps
