Rail Clips

▲Rail Clips manufacturing process▲

 

▲ Material Selection

 

Rail clips are made from high-strength steel or other durable materials capable of withstanding the stresses and demands of railway operations. The material chosen must meet specific standards and requirements for strength, elasticity, and corrosion resistance.

 

▲ Forming

 

The selected material is then processed through forming techniques such as hot forging, cold forging, or stamping to shape it into the desired rail clip design. This involves applying pressure to the material using specialized machinery to create the necessary contours, holes, and dimensions.

 

▲ Heat Treatment

 

After forming, the rail clips may undergo heat treatment processes such as quenching and tempering to improve their mechanical properties. Heat treatment helps enhance the strength, hardness, and toughness of the material, ensuring that the rail clips can withstand the loads and stresses experienced in railway applications.

 

 

▲ Surface Treatment

 

Rail clips often undergo surface treatment processes to improve their corrosion resistance and durability. This may include techniques such as galvanization, zinc coating, or other protective coatings to protect the rail clips from environmental factors such as moisture, chemicals, and abrasion.

 

▲ Assembly

 

Depending on the design of the rail clip and the specific requirements of the railway track system, additional components such as nuts, bolts, or washers may be assembled onto the rail clip. This ensures that the rail clip can be securely attached to the rail and the underlying base.

 

▲ Quality Control

 

Throughout the manufacturing process, rigorous quality control measures are implemented to ensure that the rail clips meet the required standards and specifications. This includes inspections of raw materials, dimensional checks during forming, and testing of mechanical properties, surface finish, and corrosion resistance.

 

▲Types of Rail Clips▲

 

▲ Elastic Rail Clips

 

Elastic Rail Clips are among the most widely used rail clips in modern railway systems. They feature a spring-like design that provides elasticity, allowing the rail to expand and contract with temperature changes while maintaining a secure grip on the rail base. Elastic rail clips help absorb shocks and vibrations, reducing noise and extending the life of the track components.

 

▲ Pandrol Clips

 

Pandrol clips are a type of elastic rail clip widely used in railway tracks worldwide. They provide continuous clamping force to the rail, ensuring stability and reducing the risk of rail movement and derailments. Pandrol clips are known for their reliability, durability, and ease of installation.

 

▲ KPO Clips

 

KPO clips, also known as SKL clips, are commonly used in heavy-haul railway tracks. They feature a sturdy design with high clamping force, making them suitable for applications where heavy loads and high speeds are involved. KPO clips are often used in conjunction with resilient pads to further reduce noise and vibration.

 

▲ Crane Rail Clips

 

Crane Rail Clips are specifically designed for securing crane rails, which are used in industrial settings for heavy-duty applications such as ports, factories, and warehouses. Crane rail clips are typically robust and durable to withstand the extreme loads and conditions encountered in crane operations.

 

▲ Deenik Clips

 

Deenik clips, also known as Deenik fasteners, are commonly used in tramway and light rail systems. They feature a simple design with a threaded shank that is bolted to the rail base, providing secure fastening while allowing for easy installation and maintenance.

 

▲ PR Clips

 

PR clips are designed for long-term use without the need for frequent adjustments or replacements. They provide a reliable and low-maintenance solution for securing rails to the base, ensuring stability and safety in railway tracks.

 

 

▲Rail Clips maintenance▲

 

▲ Regular Inspections

 

Conduct regular visual inspections of rail clips to identify signs of wear, damage, or deterioration. Inspect for loose bolts, cracked or broken clips, corrosion, and any other abnormalities that may affect the performance of the rail clips.

 

▲ Tightening

 

Check the tightness of bolts or fasteners securing the rail clips to the rail base. Loose bolts can compromise the integrity of the rail clip and lead to rail movement or failure. Tighten loose bolts to the manufacturer's recommended torque specifications.

 

▲ Replacement

 

Replace damaged or worn rail clips as needed. This may involve removing the old clips and installing new ones to ensure proper fastening and stability of the rail. Pay attention to areas where rail clips are frequently subjected to high loads or wear, such as curves, switches, and crossings.

 

▲ Cleaning

 

Keep rail clips clean and free of debris, rust, grease, or other contaminants that may interfere with their performance. Use appropriate cleaning methods and equipment to remove dirt and debris from the rail clips and surrounding areas.

 

▲ Lubrication

 

Apply lubricants to moving parts of rail clips, such as springs or sliding surfaces, to reduce friction and wear. Lubrication helps maintain the functionality and longevity of rail clips, especially in areas with high levels of vibration or exposure to harsh environmental conditions.

 

▲ Corrosion Protection

 

Implement measures to protect rail clips from corrosion, such as applying corrosion-resistant coatings or galvanizing. Regularly inspect the condition of the coatings and touch up or reapply as necessary to prevent corrosion damage to the rail clips.

 

▲ Specialized Maintenance

 

Some types of rail clips, such as elastic clips or Pandrol clips, may require specialized maintenance procedures. Follow the manufacturer's recommendations for inspection, adjustment, and maintenance of these clips to ensure optimal performance.

 

▲ Record Keeping

 

Maintain detailed records of rail clip maintenance activities, including inspection dates, findings, repairs, and replacements. This information helps track the condition of rail clips over time and identify trends or patterns that may require attention.

 

 

▲Rail Clips application▲

 

▲ Preparation

 

Before installing rail clips, the railway track must be properly prepared. This includes ensuring that the rail base is clean, level, and free of debris or obstructions that could interfere with the installation process.

 

▲ Positioning

 

Rail clips are positioned along the rail at predetermined intervals based on the track design and specifications. The spacing between rail clips depends on factors such as rail type, track curvature, and anticipated loads.

 

▲ Installation

 

Rail clips are typically installed by placing them onto the rail base and securing them in place using bolts or other fasteners. The clips are positioned so that they grip the rail tightly, providing sufficient clamping force to hold the rail securely in place.

 

▲ Adjustment

 

In some cases, rail clips may require adjustment to ensure proper alignment and tension. This may involve tightening or loosening bolts to achieve the desired clamping force and ensure that the rail is securely fastened to the base.

 

▲ Verification

 

Once rail clips are installed, they are inspected to ensure that they are properly positioned and securely fastened to the rail base. This may involve visual inspections or using specialized tools to measure clamping force and alignment.

 

▲ Resilient Pads

 

In some track systems, resilient pads or insulators are installed between the rail and the rail clip to dampen vibration and reduce noise. These pads help improve the performance and longevity of the rail clip assembly.

 

▲ Final Checks

 

After installation, final checks are conducted to verify the integrity and stability of the rail clip assembly. This includes ensuring that all bolts are properly tightened, and there are no signs of damage or defects that could affect the performance of the rail clip.

Q: What are rail clips used for?

A: Rail clip is a component of railway fastening systems. It is used to fix the railroad track to the underlying baseplate and sleepers. The clamping force by rail clips helps to maintain the gauge and prevent the rail from moving in the vertical and horizontal direction relative to the sleeper.

 

Q: What is the process of elastic rail clip manufacturing?

A: The schedule of production process is as follows: Shearing → Heating to forging temperature → Forming → Hardening → Tempering → Inspection → Packing. The raw material which is spring steel bar has to be sheared as per length required. The sheared rods are heated to the forging temperature at 950OC to 1000OC.
