What are the advantages of using Rail Elastic Clips in concrete sleepers?

Rail clips are tools utilized for securely attaching rails to the baseplate underneath them. Their main purpose is to keep the rail stable and prevent any shifts that may cause alignment issues or accidents. The selection of materials and design for rail clips is carefully done to ensure durability, in weather conditions and mechanical pressures often faced in railway activities.

As an OEM & OBM manufacturer, GNEE RAIL is capable of not only producing a wide range of internationally common types of rail clips, such as W Tension Clamp, e-Clip, Fast-Clip, SKL Tension Clamp, Nabla Blade, etc., but also customizing products tailored to our customers' specific requirements.

Using rail elastic clips with concrete sleepers provides vital elasticity to a rigid system, reducing wear, absorbing shock, and maintaining the rail's stability. These clips absorb vibrations from passing trains, decrease noise, and have a long service life with low maintenance, which increases the overall track lifecycle and reliability.

Advantages of using rail elastic clips

• Adds elasticity to rigid concrete: The primary advantage is providing the necessary flexibility that concrete alone cannot.

• Absorbs impact and vibrations: They absorb impact energy and vibrations from passing trains, which helps prevent damage to the sleepers and reduces noise.

• Ensures stability and correct alignment: The clips prevent vertical and horizontal movement, resisting creep and torsional forces to keep the rails in their correct position.

• Increases track lifecycle: By reducing wear and tear, elastic clips help extend the service life of the track components.

• Lowers maintenance costs: They have a long service life and require less frequent maintenance, and can sometimes be re-used without losing properties.

• Protects concrete sleepers: Their design helps prevent degradation of the concrete from repeated loading.

• Provides electrical insulation: They maintain electrical insulation between the rail and the reinforced concrete sleeper, which is crucial for track circuits.

What's the function of rail clip?

Rail track supports vehicle and is fixed to the railway sleeper by rail fastening system. As the core part of rail fastening system, the bending and distortion of rail clip will produce crimping force on the rail track, which ensure the reliable connection between rail tracks and keep the integrity of rail track. Besides, the rigid contact of vehicle and rail track will cause vibration, the elastic structure of rail clip can absorb the impact energy during the train operation, reduce the shocking. The elastic rail clip works under the repeated alternating stress. It bears various effects such as bending, torsion, fatigue and corrosion. When the vehicle passes, it also bears extremely high instantaneous impact load.

Furthermore, GNEE RAIL offers a diverse range of products and services, including OEM and OBM rail fastening systems for conventional, high-speed, heavy-haul, and metro applications. Its portfolio includes rail clips, pads, tie plates, bolts, and other specialized components. Comprehensive laboratory facilities ensure all products meet rigorous standards, including EN 13146, EN 13481 internationally, and TB standards domestically in China.
