Rail Shoulder, Casting Shoulder and Weld-on Shoulder

A rail shoulder is a pre-inserted item in the concrete sleepers, no matter for single stem type or twin stem type, used to fix the elastic rail clips, mainly e-clips, within the fastening system.

Two types of rail shoulders for rail clips are available: cast-in shoulder and weld-on shoulder.

Casting Rail Shoulders

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.

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. Other materials available: QT600-3, QT700-2, ZG25, ZG35, ZG45, etc.

Standard compliance: 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 Shoulder

Weld-on shoulder is made by hot forging, used for places where standard sleepers are unable to be easily used. The shoulders are welded on the flat steel base plates. It fabricates the rail retaining units on both the steel ties and base plates, according to AREMA standard.

Weld-on shoulders can be applied for Pandrol style clips with a range of 30lbs to 113lbs.

Special Rail Shoulder

Produced by hot forging, these are used together with rail clip bolts and special rail clips to fasten the rail, utilizing low or mid carbon steels.

Overview & Components

Freight wagons require a large number of spare parts during long-term operation. Comprehensive supply solutions cover most of the spare parts needed for a freight wagon.

The wheel set is a key component of the Railway Bogie. It is the most common and important spare part in the railway industry. One wheel set contains two wheels, one axle, and two bearings. Depending on application, other parts like gears, brake discs, and axle boxes are included.

They are used on wagons, locomotives, passenger cars, and more. Wheels can be cast or forged based on customer requirements.
