Product Description

A rail shoulder is a pre-inserted item in concrete sleepers, whether single stem or twin stem type, used to fix elastic rail clips (primarily e-clips) within the fastening system. We specialize in producing two distinct types: cast-in shoulders and weld-on shoulders.

Casting Rail Shoulders

Cast-in shoulders are manufactured from iron casting and pre-embedded in concrete sleepers. They work in tandem with elastic clips to secure the rail. Material options include M.C.I. (malleable iron) and S.G.C.I. (spheroid graphite iron), with other grades available such as QT600-3, QT700-2, ZG25, ZG35, and ZG45.

Standards: GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, KS D 4302, GOST 7293, or BS EN 1563.

Weld-on Shoulder

Produced via hot forging, weld-on shoulders are utilized where standard sleepers are impractical. These are welded onto flat steel base plates to create rail retaining units on steel ties and base plates, typically following AREMA standards. They are compatible with Pandrol style clips ranging from 30lbs to 113lbs.

Special Rail Shoulder

Customized shoulders can also be produced through hot forging for use with rail clip bolts and specialized rail clips, utilizing low or mid-carbon steel materials.

Technical Description: Railway Wheel Sets

The wheel set is a critical component of the Railway Bogie and one of the most vital spare parts in the industry. A standard wheel set consists of two wheels, one axle, and two bearings. Depending on application requirements, additional parts like gears, brake discs, and axle boxes may be integrated.

Configurations are determined by vehicle and bogie performance parameters, suitable for wagons, locomotives, and passenger cars.

Frequently Asked Questions

1. What is the primary function of a rail shoulder? A rail shoulder is pre-embedded into concrete sleepers to provide a secure anchoring point for elastic rail clips, ensuring the rail remains fixed within the fastening system.
2. What are the main differences between cast-in and weld-on shoulders? Cast-in shoulders are embedded directly into concrete during sleeper production, while weld-on shoulders are forged and welded onto steel base plates for specialized track locations.
3. Which materials are used for casting rail shoulders? Common materials include Malleable Cast Iron (M.C.I.) and Spheroid Graphite Cast Iron (S.G.C.I.), along with QT600-3, QT700-2, and various ZG steel grades.
4. What components are included in a standard railway wheel set? A standard set includes two wheels, one axle, and two bearings. It may also include gears or brake discs depending on the locomotive or wagon type.
5. Which international standards do your products comply with? Our components meet major global standards including UIC 813 (International), EN 13260 (European), BS 5892-6 (British), and JIS E4504 (Japanese).
6. Are custom forged shoulders available for specific rail clips? Yes, special rail shoulders can be hot-forged from low or mid-carbon steel to accommodate specific bolt types and unique rail fastening requirements.
