Product Description
Rail shoulder, also called rail iron shoulder, is mainly used to be casted in the concrete ties to fixate elastic rail clips. According to the shape, it can be classified into Single Stem Rail Iron Shoulder and Twin Stems Rail Iron Shoulder. Besides, according to the manufacturing ways, rail shoulder can be divided into 3 types: casting rail shoulder, weld-on rail shoulder and hot forging rail shoulder.
The rail shoulder is embedded in concrete at the time of casting, it's used to grips the clip effectively and provides lateral support to rail.
The Rail shoulder is semi-embedded part cast in the concrete rail ties to fix the elastic rail clip to the base plate. There are two common types of rail shoulders available: Cast-in Shoulder and Weld-on Shoulder, both of which are used for the fixing of elastic rail clips. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties.
Quality Control System
All processes are in accordance with the requirements of ISO quality management system. From supplier quality control to finished products, strict standard procedures are followed:
1
Raw Material Inspection: Before production, raw materials are checked for chemical composition, mechanical properties, and production batch numbers.
2
Batch Testing: Inspectors conduct sample sampling and batch testing throughout the manufacturing process to maintain control standards.
3
Physical & Chemical Testing: Depending on requirements, specific testing is conducted. Materials that do not meet standards are strictly refused.
4
Technical Guidance: We organize quality coordination meetings and provide technical advice for semi-finished products to ensure qualified delivery.
Frequently Asked Questions (FAQ)
What is the primary function of a rail shoulder?
It is embedded in concrete ties to effectively grip elastic rail clips and provide essential lateral support to the rail tracks.
What are the different types of rail shoulders by manufacturing method?
Rail shoulders are generally classified into three types: casting rail shoulders, weld-on rail shoulders, and hot forging rail shoulders.
What is the difference between Single Stem and Twin Stem shoulders?
Single Stem Iron Shoulders are typically used in pre-stressed concrete ties, while Twin Stem Iron Shoulders are designed for Bi-Block or Twin Block concrete ties.
How is the quality of the raw materials ensured?
Suppliers must provide production batch numbers, chemical composition reports, and mechanical property indicators before the material is accepted for production.
Is the production process certified?
Yes, all manufacturing and quality control processes are conducted in strict accordance with ISO 9001 management system requirements.
