The rail shoulders are cast on the concrete sleepers and are used to fix the elastic rail clips. There are two types of rail shoulders to choose from, pre-embedded rail shoulders and welded rail shoulders, both of which are used to hold elastic rail clips.
Kingrail Parts can produce various rail shoulders according to UIC, AREMA, GB, NF EN 1563(1997), DIN, JIS, BS and other standards.
Embedded Shoulders:
Cast shoulders as embedded parts of railway fastening systems, pressed into concrete sleepers and fastened to the rail together with E-clips. Cast shoulders are made of cast 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) .

Welding Shoulder:
Hot forging is used for the welding shoulder, which is used in places where standard sleepers cannot be easily used, and the shoulder needs to be welded on the flat steel base plate. In this way, it is possible to manufacture rail fixing units on rails and base plates, always in accordance with AREMA standards.
Welded shoulders are available for Pandrol clips ranging from 30 lbs to 113 lbs.
Special Rail Shoulders:
This type of shoulder can also be made by hot forging, with rail clamp bolts and special rail clamps to fix the rail, and the material is low carbon steel or medium carbon steel.
