Product Overview

A rail shoulder is a pre-inserted item in concrete sleepers, available for both single stem and twin stem types. It is designed to secure elastic rail clips, primarily e-clips, within the rail fastening system. We specialize in two primary types of rail shoulders: cast-in shoulders and weld-on shoulders.

Casting Rail Shoulders

Cast-in shoulders are manufactured using iron casting. These are pre-embedded into concrete sleepers and work alongside elastic clips to provide robust rail fastening. Available materials include M.C.I. (Malleable Cast Iron) and S.G.C.I. (Spheroid Graphite Cast Iron). Other specialized grades like QT600-3, QT700-2, ZG25, ZG35, and ZG45 are also available.

Weld-on & Special Shoulders

Weld-on shoulders are produced via hot forging. They are ideal for locations where standard sleepers cannot be used, allowing the shoulders to be welded onto flat steel base plates. Special forged shoulders are also used with rail clip bolts for specific fastening requirements.

Frequently Asked Questions

Q1: What materials are used for cast-in rail shoulders? A: We typically use Malleable Cast Iron (M.C.I.) and Spheroid Graphite Cast Iron (S.G.C.I.), with grades such as QT500, QT600-3, and QT700-2 depending on the project requirements.

Q2: When should I choose a weld-on shoulder over a cast-in shoulder? A: Weld-on shoulders are used when standard concrete sleepers are not feasible. They are welded directly onto flat steel base plates or steel ties, often following AREMA standards.

Q3: Which international standards do your railway products comply with? A: Our products meet various global standards including BS EN 1563, UIC 813, TB/T 1718, EN 13260, and JIS E4504.

Q4: Can you provide customized forged shoulders? A: Yes, we can produce special shoulders via hot forging using low or mid-carbon steel to match specific rail clip bolts and fastening systems.

Q5: What is the typical production capacity for rail shoulders? A: Our facility has a production capacity of approximately 500,000 pieces per year, ensuring steady supply for large-scale railway projects.

Q6: Are the wheelsets available for different types of railway vehicles? A: Yes, our wheelsets are designed for use on freight wagons, locomotives, and passenger cars, with configurations tailored to specific bogie performance parameters.
