Product Description

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

Casting Rail Shoulders

Cast-in Shoulders are manufactured through iron casting. These components are pre-embedded into concrete sleepers and work in conjunction with elastic clips to secure the rail. Material options include M.C.I. (malleable iron) and S.G.C.I. (spheroid graphite iron). Standard compliance includes GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, and BS EN 1563.

Weld-on Shoulders

Weld-on shoulders are produced via hot forging. These are utilized in locations where standard sleepers are not easily applied, requiring the shoulders to be welded onto flat steel base plates. This method facilitates the fabrication of rail retaining units on both steel ties and base plates, typically following AREMA standards. They are compatible with Pandrol style clips ranging from 30lbs to 113lbs.

Special Rail Shoulders

Produced by hot forging using low or mid-carbon steel, these shoulders are used alongside rail clip bolts and specialized rail clips to ensure secure rail fastening.

Technical Overview & Components

Railway wheel sets are critical components of the railway bogie, serving as the most essential spare parts in the industry. A standard wheel set comprises two wheels, one axle, and two bearings. Depending on application requirements, additional parts such as gears, brake discs, and axle boxes may be integrated.

Frequently Asked Questions

Q1: What is the primary function of a rail shoulder?

A rail shoulder is pre-embedded in concrete sleepers to provide a secure anchoring point for elastic rail clips, ensuring the rail remains fixed within the fastening system.

Q2: What materials are used in cast-in rail shoulders?

They are typically made from Malleable Cast Iron (M.C.I.) or Spheroid Graphite Cast Iron (S.G.C.I.), with material grades like QT500, QT600-3, and ZG35 also available.

Q3: When should a weld-on shoulder be used instead of a cast-in type?

Weld-on shoulders are used when standard sleepers cannot be easily applied, allowing the shoulders to be welded directly onto flat steel base plates or steel ties.

Q4: Are your railway components manufactured to international standards?

Yes, all products comply with major international standards including UIC 813, BS EN 1563, AREMA, and DIN 1693 to ensure global interoperability.

Q5: What parts are included in a full railway wheel set?

A standard set includes two wheels, one axle, and two bearings, but can be customized with gears and brake discs based on specific locomotive or wagon requirements.

Q6: Do you provide parts for freight wagon maintenance?

Yes, we provide a full range of bogie components, draft gear systems, and air brake parts specifically designed for long-term freight wagon operation and replacement.
