Main Types of Railway Elastic Clips
| Model | Standard | Rail Type | Installation Force (kN) | Deflection (mm) | Key Features | Applications |
|---|---|---|---|---|---|---|
| Type I Clip | TB/T 1495.2 | 50kg/m | 8-10 | ≥10 | Triple-arm elastic design | Conventional lines, sidings |
| Type II Clip | TB/T 3065 | 60kg/m | 10-12 | ≥12 | Enhanced clamping force | Mainlines, heavy-haul |
| Type III Clip | TB/T 3395 | 60kg/m | 9-11 | ≥11 | Boltless fastening | Passenger lines (200km/h) |
| W-type Clip | Q/CR 563 | 60kg/m | 7-9 | ≥8 | Cost-effective triple-support | Freight yards |
| FC Damped Clip | Q/CR 749 | 60kg/m | 6-8 | ≥7 | Rubber composite layer (15dB damping) | Urban transit vibration zones |
Application of Rail Clips
When working, the spring clip fastener utilizes the bending deformation performance of the material and the torsional deformation performance of the material (especially the circular cross-section spring clip), so the elasticity is generally good, and there is basically no cross-sectional weakening, so the material utilization rate is high. On conventional lines, it is generally hoped that the fastener has a large buckling force and good elasticity. In this respect, the spring clip fastener has obvious advantages.
