Product Overview
Rail shoulders are critical components in modern rail fastening systems that provide lateral restraint and maintain gauge stability. These precision-engineered elements transfer horizontal forces from the rail to the sleeper while allowing controlled vertical movement.
Types of Rail Shoulders
Standard Shoulder Types
| Type | Material | Load Capacity | Applications |
|---|---|---|---|
| Cast Iron | EN-GJS-400 | 25kN | Conventional tracks |
| Composite | Glass-fiber reinforced polyamide | 18kN | Insulated tracks |
| Forged Steel | 42CrMo4 | 35kN | Heavy haul lines |
| Elastomeric | CR/NR blend | 12kN | Vibration-sensitive areas |
Specialized Variants
Adjustable Shoulders: For track geometry correction
Insulated Shoulders: Signalized track sections
Wide-Face Shoulders: Curved track applications
Low-Profile Shoulders: Ballastless track systems
Key Functions
Lateral Rail Restraint - Maintains track gauge within ±2mm
Load Distribution - Reduces sleeper contact pressures by 40%
Vibration Damping - Attenuates high-frequency vibrations
Electrical Isolation - Critical for signaling circuits (composite types)
