Rail shoulder is cast in the concrete rail ties to fix the elastic rail clips. There are two types of rail shoulders available, the cast-in shoulder and the weld-on rail shoulder, both of which are used for the fixing of elastic rail clips.
Material and Manufacturing Process The Pre-embedded Iron Base is usually made of high-quality cast iron or steel, which provides the necessary strength and durability to withstand the forces exerted by trains and maintain the integrity of the railway system. The manufacturing process involves precision casting or forging techniques to ensure the accuracy and reliability of the product.
Installation and Application During railway construction, the Pre-embedded Iron Base is installed in the designated position within the concrete sleeper, usually during the pouring of the concrete. Once the concrete has set, the base provides a stable platform for attaching elastic fasteners, which in turn secure the rail to the sleeper. This ensures that the track remains aligned and stable, preventing any potential derailments or accidents.
Importance in Railway Safety The Pre-embedded Iron Base plays a vital role in maintaining the safety and reliability of railway transportation. By providing a secure and stable foundation for the rail, it helps to prevent track movements and deformations, which can lead to serious accidents. Therefore, it is crucial to use high-quality materials and manufacturing techniques to ensure the durability and performance of the Pre-embedded Iron Base.
