Rail shoulder is produced by hot forging, used together with clip bolt and special rail clip to fix the rail. The material can be low carbon steel and mid carbon steel, according to our customers' requirement.
Weld-on shoulder is used for the typical position of rail. This rail cast iron shoulder is welded on flat steel plate instead of the standard tie plate and is produced according to AREA standard. Designed for use with E style elastic rail clips, the weld on shoulder fastening allows customers to fabricate rail retaining units on both steel sleepers and steel base plates.
The rail cast iron shoulders can also be welded on to longer length steel sleeper sections or bearers for use in the 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 makes it particularly useful and cost effective in this role.
The shoulder accessories are supplied for specific rail sections with design criteria which ensure that the correct elastic clip toe loading is achieved. Certain shoulders are supplied with milled weld area faces to assist in achieving the necessary weld integrity.
