🚂 Product Description

Rail shoulder is cast in the concrete rail ties to fix the elastic rail clips. There are two types of rail shoulders available, the cast-in shoulder and the weld-on shoulder, both of which are used for the fixing of elastic rail clips.

The casting shoulders as the embedded part of the rail way fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail. The cast in shoulder is made by casting from iron, such as, GB/T 1348-1988, NF EN 1563(1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293(1985) or BS EN 1563(1997).

⚙ Types of Rail Shoulder Produced

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. 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.

🔧 Cast-in Rail Shoulder Mechanical Property

Material	Tensile Strength (Mpa)	Yield Strength (Mpa)	Elongation (%)
QT400-15 (GGG40)	400	250	15
QT450-10 (GGG45)	450	310	10
QT500-7 (GGG50)	500	320	7

🚧 Weld-on Rail Shoulder

The weld-on shoulder is used at the typical position of rail where the rail shoulder is weld on flat steel plate rather than the standard tie plate. The weld-on shoulder production method is hot forging, it is fabricated according to AREA standard. The steel material type for weld-on shoulders production can be low or medium carbon steel.

The rail cast iron shoulders can be welded on to longer length steel sleeper sections or bearers, for locations where fabrication of switch and crossing layouts where vertical rail geometry is employed.

❓ Frequently Asked Questions

What are the main functions of a rail shoulder?

The rail shoulder is used to fix elastic rail clips to the base plate or concrete ties, ensuring the rail remains securely fastened within the railway fastening system.

What is the difference between cast-in and weld-on shoulders?

Cast-in shoulders are embedded directly into concrete sleepers during casting, while weld-on shoulders are welded onto flat steel plates or steel sleepers, often used in switch and crossing layouts.

Which materials are used for producing cast-in shoulders?

They are typically made from ductile iron grades such as QT400-15, QT450-10, and QT500-7, complying with international standards like ISO1038 and DIN 1693.

Can rail shoulders be customized for specific rail types?

Yes, they are compatible with various rail sections including UIC54, UIC60, 115RE, and various BS standards (80lbs, 100lbs) depending on the material grade and design.

What is the production capacity for these rail components?

The production capacity reaches up to 20,000 pieces per day, ensuring a steady supply for large-scale railway construction projects.

What standards are weld-on shoulders manufactured to?

Weld-on shoulders are generally produced using hot forging methods and fabricated according to the AREA standard using low or medium carbon steel.
