Rail Nabla Clips Specifications
| Attribute | Description |
|---|---|
| Product Name | Rail Nabla Clips/∇-type Spring Clip |
| Shape | Resembles an inverted triangle (∇), which is different from the conventional ω-type spring clips. |
| Application | Mainly used in non-passenger-carrying low-speed sections such as the storage tracks and parking tracks of urban rail transit systems like subways and light rails. |
| Material | Usually made of high-strength spring steel, such as 60Si2MnA. |
Nabla Clip vs. Other Fasteners
| Aspect | Rail Nabla Clips (∇-type Spring Clips) | Other Spring Clips (e.g., ω-type Spring Clips) |
|---|---|---|
| Shape | Resembles an inverted triangle (∇), with a distinct triangular profile. | Typically feature an ω-shaped (omega) profile, which is curved and more rounded in appearance. |
| Application Scenarios | Primarily used in non-passenger, low-speed sections such as storage tracks and parking tracks of urban rail transit (subways, light rails). | Widely applied in main lines of various railway systems, including conventional-speed railways, high-speed railways, and mixed passenger-freight lines. |
| Clamping Force | Generally lower clamping force, suitable for low-demand, low-speed track sections. | Higher clamping force (varies by model) to withstand dynamic loads from high-speed trains and heavy freight traffic. |
| Material Hardness | Typically has a hardness range of HRC 51–55. | Hardness varies by type (e.g., Chinese Type Ⅰ/Ⅱ/Ⅲ ω-clips use 60Si2MnA steel) but often falls in a different range tailored to high-stress conditions. |
