  • 1. We are engaged in manufacturing and supplying elastic rail clip products which are exclusively used in railways. Fabricated with optimum quality raw materials, these elastic rail clips are designed with high precision which impart high tensile strength and corrosion resistance. Our products can also be customized according to clients' requirement at a client desired price.

    Universally accepted in the railway industry, elastic rail clip provides high performance clamping of the rail, coupled with ease of installation.

    As out of patent technology from both manufacturers (Pandrol and Vossloh) has become available to the general supply market, SUYU has linked up with reputable quality manufacturers to offer a cost effective range of elastic rail clip to suit many rail sections and applications as well as selected SKL tension clamp.

    Strict dimensional control, as well as the use of high quality spring steel, ensure that the elastic rail clip and other elastic railway fastenings supplied by SUYU are within specified ranges aimed at meeting customer requirements.

    We are extremely capable of producing elastic rail clip for any type of toe load and axle load requirements to fix the rails on wooden, steel or concrete sleepers. We offer various elastic rail clip with size steel bar diameter from 12mm to 20mm. We manufacture different types of elastic rail clips with flat toe for broad gauge line, having the toe load from 850kgf to 1100kgf, and are capable of providing any type of toe load and axle load to fix the rails on wooden, steel or concrete sleeper.


    2. We are the principal manufacturer and exporter of SKL tension clamp, which ensures the electric insulation of the rail on its support. These tension clamps are mainly used to maintain the rail elastically on its support, in both the vertical and transverse directions. We have provided a fixing and supporting device for a rail, comprising a support defining table for the rail and a projecting shoulder on each side of said table, a pad interposed between the rail and the support table, an insulating clip having a body cooperative with the shoulder and a nose portion bearing against the flange of the rail, at least one elastically yieldable strip, and fixing equipment extending through apertures of the body of the elastic rail clip and the strip.
    Our elastic rail clip is a boltable clip with high permanent clip strength. This rail clip is especially applied in rail construction with concrete sleepers with the diameter
    13mm to 15mm, range from SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, etc.

    3. We produce PR series elastic rail clip, such as PR309, PR401, and PR601

    4. Fast Clip
    The fast clip is designed with a captive system. Sleeper manufacturers shall assemble the components on the sleeper before delivery. This product is specially offered for the mechanized track renewals requiring automated clipping machines or hand tools. The clip for the system is manufactured in the shape of M, driven at right angles to the rail. Specially provided for 26t axle load, the fast clip can be produced for heavy haul rail with the axle load up to 40t.

    A. Shoulders insusceptible to accidental damage
    B. Robust toe insulators
    C. Less and simple hand tools required for installation
    D. Easy to use in the concrete sleeper factory

    One of the key features of the fast clip system is the new plastic seal plate, which is used to seal the hole in the sleeper mold and is then cast into the sleeper. This design minimizes the contact between the steel mold and the cast iron shoulder of the assembly, increasing mold life accordingly. It also prevents slurry from leaking into the shoulder.


    5. Fist Clip
    The fist clip is produced from 60Si2MnA. Packed in wooden box, this product can be manufactured with plain, black, or red surface.

    These fist clips have been widely used by clients in South Africa, Zimbabwe, Botswana, Swaziland and Namibia.
