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 Process

Raw Material Testing: Before producing Rail Shoulder, we check and test raw materials, requiring production batch numbers, chemical composition, and mechanical properties.

Batch Inspection: Quality control inspectors perform sample sampling and batch testing post-manufacturing, providing material certificates for testing process control.

Physical & Chemical Analysis: Corresponding physical and chemical tests are conducted based on specific requirements. Materials are only accepted if they meet strict standards.

Technical Guidance: We organize quality control coordination meetings and provide technical advice to ensure that qualified products are delivered prior to shipment.

Frequently Asked Questions

1. What is the primary function of a rail shoulder?

A rail shoulder is embedded in concrete ties during casting to effectively grip elastic rail clips and provide essential lateral support to the rail tracks.
