Ningbo Supreme Machinery Co., Ltd is a professional gray iron and ductile Iron casting manufacturer and supplier in China. The cast iron rail shoulder is a semi-embedded part into the sleeper to fasten the clip to the base plate, and protect the clip from being stolen. We could supply different types of shoulders satisfying clients' needs.
1. rail shoulder is manufactured in one-piece construction for spring steel or equal, heat-treated and designed to eliminate creepage of truck. The rail shoulder provide a large bearing surface against both rail base and tie, avoiding undo cuttings and wear, thus prolonging the life of wooden lines. The rail anchors are used in 50Kg, 85Kg, 90 / 91LB, 115RE / 136RE, UIC54 and UIC60 rail.
2. The Russian rail shoulder is a kind of casting product used in the construction of railway. It is made of QT400-15 material. Its mechanical properties in the as-cast state are fully compliant to the TOCT 7293-85
With our own R&D department, we have succeeded and continue to produce new rail anchor according to our customers' request. If you are interested in railway components, please contact us and we always offer the professional help to meet your needs.
