A rail shoulder is a pre-inserted item in concrete sleepers, whether single stem or twin stem type, used to fix elastic rail clips (primarily e-clips) within the fastening system. We specialize in producing two distinct types: cast-in shoulders and weld-on shoulders.

Casting Rail Shoulders

Cast-in shoulders are manufactured from iron casting and pre-embedded in concrete sleepers. They work in tandem with elastic clips to secure the rail. Material options include M.C.I. (malleable iron) and S.G.C.I. (spheroid graphite iron), with other grades available such as QT600-3, QT700-2, ZG25, ZG35, and ZG45.

Standards: GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, KS D 4302, GOST 7293, or BS EN 1563.

Weld-on Shoulder

Produced via hot forging, weld-on shoulders are utilized where standard sleepers are impractical. These are welded onto flat steel base plates to create rail retaining units on steel ties and base plates, typically following AREMA standards. They are compatible with Pandrol style clips ranging from 30lbs to 113lbs.

Special Rail Shoulder

Customized shoulders can also be produced through hot forging for use with rail clip bolts and specialized rail clips, utilizing low or mid-carbon steel materials.

Freight wagons require a wide array of spare parts during long-term operations. As a specialist railway supplier, we provide essential components needed for freight wagon maintenance and assembly.

The wheel set is a critical component of the Railway Bogie and one of the most vital spare parts in the industry. A standard wheel set consists of two wheels, one axle, and two bearings. Depending on application requirements, additional parts like gears, brake discs, and axle boxes may be integrated.

Configurations are determined by vehicle and bogie performance parameters, suitable for wagons, locomotives, and passenger cars.
