How do Rail Clips protect sleepers?

Rail clips protect sleepers by securely fastening rails to them, which prevents excessive movement and absorbs the shock and vibration from passing trains. They also accommodate thermal expansion and contraction of the rails, and work with other components like rail pads to provide cushioning and reduce wear on the sleeper.

How rail clips protect sleepers

• Securely fasten the rail: Their primary function is to clamp the steel rail to the sleeper, preventing horizontal and vertical movement and maintaining a consistent track gauge.

• Absorb shock and vibration: The elastic nature of many clips allows them to absorb impact energy and vibrations from passing trains, reducing stress on the sleepers and the overall track structure.

• Accommodate thermal expansion: They allow steel rails to expand and contract with temperature changes without creating excessive stress, which helps prevent buckling and damage to the sleepers.

• Provide cushioning (with rail pads): When used with a rail pad, the clip secures the pad, which is a layer of elastic material placed between the rail and the sleeper. This pad further protects the sleeper from wear and impact.

• Contribute to a stable track structure: By maintaining a stable and secure connection, rail clips ensure the long-term integrity and safety of the entire track system.

Elastic Rail Clip Manufacturing Process

• Raw material

• Shearing

• Heating to forging temperature

• Forming

• Quenching – Tempering

• Inspection – Packing

Raw material refers to a long spring steel rod. The first step is to shear the raw materials into the required length. Then put the sheared spring steel into the heating furnace. The temperature in the furnace is 950-1000℃. After heating, the clips are formed through three stages of bending by hot molding equipment. After forming, the elastic rail clips are conveyed to a quenching oil tank. After quenching, the elastic rail clips are tempered at 400-500°C. The elastic rail clips are finally oiled and packed. The elastic rail clips must have a hardness between 40 and 48 HRC.

From the first step of raw material purchasing to the final step of finished products, we do strict inspections. GNEE RAIL uses high precision inspection machines to make sure the finished elastic rail clips meet the requirements.
