Elastic Rail Clip

Rail elastic clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. Usually rail clips are made of forged spring steel which is produced by hot forging process. Because of the uniform microstructure of forged clips, it is considered to be better than other metal forming process.THRAIL offer an extensive range of rail clips with optimum quality, these rail clips are designed with high precision and made up of premium grade spring steel. THRAIL has been the largest and most competitive production base of rail clip in China after more than 20 years’ rail clip producing experience, and have qualification to tender nationally large and medium scaled rail projects. What’s more, our rail clip can be customized according to clients’ requirements.

We produce Various kinds of rail clips of E-type(E1609, E1809, E1817, E2007, E2009, E2055,etc), SKL tension clamps (SKL1, SKL3, SKL12, SKL14, SKL75, etc), PR series, Nabla clips, gauge lock clip, Deenik clip as well as other standard and non-standard clips (e.g. Pandrol and Vossloh) can be customized by drawings or samples.

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, THRAIL 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 THRAIL 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

6. Rail Deenik Clip

The rail Deenik clip is widely used in South America. It has a diameter of 16mm and adopts spring steel 60Si2MnA as its material. The invention of rail clips revolutionized the speed of the railway transportation. As the manufacturer of rail clips, we are proud of our high quality products and good after-sale service, which have been appraised by many clients.

7. 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.

Features

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.

8. Fist Clip

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

Rail clip processing procedures includes:
1.     Raw material purchasing
2.     Shearing
3.     Heating to forging temperature
4.     Forming
5.     Hardening
6.     Tempering
7.     Surface treatment
8.     Inspection-Packing
To produce rail clips usually use spring steel bar as the raw materials, before heating, raw materials must be sheared according to the length required. Then they are heated to 950℃ to 1000℃, next works transfer the heated bar to power press for forging, in accordance with drawing three sets of dies and fixtures are kept before hammering. The following procedure is to convey the forged rail clips to quenching tank. Then check the dimensional accuracy and quench hardness of the rail clips. The next procedure is tempering to achieve appropriate toughness in the spring. And the final step is to pack the rail clips after serious inspection.
Quality control
THRAIL has strict test and completely authentication at every single step of manufacturing rail clips and a full set of quality control system, from raw material purchasing to the finished rail clip packing. We have a professional inspection team to check about each process of the production line.
