Rail Shoulder

Rail Shoulder in Fastening System

What Types of Rail Shoulder AGICO Produce

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 from AGICO, Cast-in Shoulder and Weld-on Shoulder, both of which are used for the fixing of elastic rail clips. 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

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).

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, which varies with your specific requirements.

For the record: 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. The railway shoulder's ability to be welded in the specific position as dictated by the layout design, this makes it particularly useful and cost effective in this case.
