Material & Manufacturing
Manufactured from high-quality malleable cast iron, these rail shoulders undergo precision casting processes to ensure dimensional accuracy and structural reliability. The material composition provides exceptional strength and durability to withstand heavy railway loads.
Installation & Application
During railway construction, the pre-embedded iron base is positioned within the concrete sleeper during pouring. Once the concrete sets, it creates a stable platform for attaching elastic fasteners that secure rails to sleepers, maintaining proper track alignment and preventing derailments.
Safety & Performance Features
- Maintains track stability and prevents rail movement
- High tensile strength (400-500 MPa) for heavy load applications
- Controlled hardness (130-230 HB) for optimal wear resistance
- Precision manufacturing ensures reliable performance
- Essential for railway safety and accident prevention
