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 a 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

As an ISO 9001 certified provider, all processes are in accordance with the requirements of the quality management system. From supplier quality control to finished products, we follow strict standard procedures:

Raw Material Inspection: Before producing Rail Shoulder, we check and test the raw materials, requiring suppliers to provide production batch numbers, chemical composition, and mechanical properties.

Process Monitoring: Quality control inspectors perform sample sampling and batch testing after manufacturing, providing raw material certificates to control the testing process.

Physical & Chemical Testing: We conduct specific physical and chemical inspections. Materials are only accepted if they meet rigorous internal standards.

Technical Guidance: We organize quality control coordination meetings and provide technical guidance to ensure qualified products are delivered.

Frequently Asked Questions

What is the primary function of a rail shoulder?

The rail shoulder is used to fix elastic rail clips to the base plate or concrete ties, providing essential lateral support to the rail and ensuring the clips grip effectively.

What are the different types of rail shoulders by manufacturing method?

Rail shoulders are primarily manufactured through three methods: casting, welding (weld-on), and hot forging.

Where is the Single Stem Rail Iron Shoulder typically used?

Single Stem Iron Shoulders are commonly used in pre-stressed concrete ties to secure the fastening system.

How is quality maintained during the production of rail shoulders?

Quality is maintained through an ISO 9001 certified system which includes testing raw material chemical composition, mechanical properties, and batch sampling after manufacturing.

Can rail shoulders be used with Bi-Block concrete ties?

Yes, Twin Stem Iron Shoulders are specifically designed for use in Bi-Block or Twin Block concrete ties.

What information is verified before production begins?

Before production, the batch number, chemical composition, and mechanical properties of all raw materials are strictly inspected to ensure they meet technical indicators.
