Railway Shoulder
| Specification Category | Details |
|---|---|
| Product Name | Railway Shoulder (Also called Track Shoulder, Sleeper Shoulder, or Rail Fastener Shoulder) |
| Core Function | - Provide lateral support for rails to prevent sideward displacement (critical for curved tracks or high-speed lines) - Serve as a mounting base for rail fasteners (e.g., clips, anchors, or bolts) to secure rails to sleepers - Maintain consistent rail gauge (distance between two parallel rails) under dynamic loads (train passing, vibration) - Protect sleeper edges from wear caused by fastener friction or environmental erosion |
| Key Structural Features | - Shape: Rectangular, trapezoidal, or curved (matches sleeper top profile; curved designs enhance rail ) - Mounting Interface: Pre-drilled holes (for bolted fasteners) or integrated slots (for snap-on clips like Pandrol E-Clips) - Height: 25–60 mm (varies by rail height and fastener type; ensures fasteners fully clamp rail base) - Width: 30–80 mm (sufficient to bear lateral loads without sleeper cracking) - Chamfers: 2–5 mm radius on edges (prevents stress concentration and damage during installation) |
Material & Surface Treatment
| - Base Material | - Concrete (for integral shoulders): C50/C60 pre-stressed concrete (compressive strength ≥ 50 MPa) - Metal (for separate shoulders): Carbon steel (Q235, Q345), stainless steel (304 for corrosion resistance) - Composite: Glass fiber-reinforced plastic (GFRP), nylon 66 with glass fiber (GF30) - Wood: Hardwood (oak, beech; moisture content ≤ 18%) |
| - Surface Treatment | - Metal shoulders: Hot-dip galvanizing (≥ 60 μm thickness; salt-spray resistance ≥ 300 hours), powder coating (epoxy resin; for aesthetic and corrosion protection) - Composite shoulders: UV-stabilized coating (prevents aging from sunlight) - Concrete shoulders: Smooth finish (Ra ≤ 6.3 μm; reduces friction with fasteners) |
