The rail shoulder, also known as the railway shoulder, is a pre-inserted item in the concrete sleepers, no matter for single stem type or twin stem type, used to fix the elasticrail clips, mainly e-clips, within the fastening system. There are two types of rail shoulders available, the cast-in shoulder and the weld-on rail shoulder, both of which are used for the fixing of elastic rail clips.
Cast in Shoulder is made by casting from iron, and such shoulder is used by being pre-embedded in the concrete sleepers and works with the elastic clip to fasten the rail.
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 railroad tie plate. The weld-on shoulder is produced by hot forging, according to AREA standard. The materials for weld-on shoulders production can be low or mid carbon steel, based on the customer’s requirements.
For materials, cast in shoulder includes 3 types: M.C.I. shoulder by malleable iron and S.G.C.I. shoulder by malleable iron and S.G.C.I. shoulder by spheroid graphite iron.
