Rail Anchor for Clamp Onto The Base of Rail
What Is Rail Anchor?
Rail anchor, also known as track anchor, is a device to help maintain the proper line and gauge of track by resisting the longitudinal movement of rails under traffic and maintaining proper expansion allowance at joint gaps for temperature changes. The main function of these anchors is to prevent the rails from moving, which could lead to derailments or other safety hazards.Rail anchors are essential components of a railway track, playing a vital role in ensuring the safety and stability of the entire system.
Rail anchors are typically made of cast iron, steel, or other durable materials, and come in various shapes and sizes depending on their intended use. They are installed between the rail and sleeper, with their unique design creating a wedge-like effect that grips the rail and prevents it from shifting.
The significance of rail anchors in railway tracks cannot be overstated. Without these vital components, the rails would be free to move, leading to unstable tracks, increased wear and tear, and a higher risk of accidents. Rail anchors also help to reduce noise and vibration levels, creating a more comfortable experience for passengers and nearby residents.
Types of Rail Anchors
There are several types of rail anchors, and their selection depends on the type of railway tracks and the specific requirements of the system. Following types of rail anchors are quite popular in the market.
=>Elastic Rail Anchors
Elastic rail anchors, also known as resilient rail anchors, are designed to absorb the vibrations caused by passing trains. They are made of rubber or other elastic materials, which allows them to flex and compress as the train passes, reducing the impact of the vibrations on the track. Elastic rail anchors are commonly used in areas with high-speed trains, where the vibrations can be more severe.
=>Drive-on Rail Anchors
Drive-on rail anchors, as the name suggests, are driven onto the rail base using a hammer or other tools. They are commonly used in areas with heavy train traffic, such as mainline tracks, and can be used with most types of rail sizes and materials.
=>Spring Type Rail Anchors
Spring type rail anchors are similar to elastic rail anchors, but they are made of steel and are designed to be more durable. They are commonly used in areas with heavy train traffic and can withstand high levels of stress and vibrations.
=>Double Shoulder Rail Anchors
Double shoulder rail anchors are designed to provide a more secure grip on the rail base and sleepers. They have two shoulders on either side, which provide a better grip and prevent the rail from shifting or moving out of place.

Installation Instructions
Installation of Rail Anchors
1.Select the appropriate rail anchor for the specific application
2.Clean the sleeper or tie - Before installing the rail anchor, the sleeper or tie should be cleaned of any debris or dirt to ensure a secure fit.
3.Position the rail anchor - The rail anchor should be positioned on the sleeper or tie, with the curved end facing the base of the rail. The anchor should be placed in the center of the rail base, and its orientation should be consistent throughout the installation process.
4.Hammer the rail anchor - Once the rail anchor is in position, it should be hammered into place using a sledgehammer. The anchor should be hammered until it is snug against the base of the rail.
5.Test the rail anchor - After the rail anchor is installed, it should be tested for tightness and stability. Any loose rail anchors should be re-positioned and re-hammered until they are secure.
Maintenance of Rail Anchors
1.Inspect rail anchors regularly. These inspections should be conducted at least once per year, or more frequently in high-traffic areas.
2.Replace damaged or loose rail anchors. Rail anchors that are no longer snug against the base of the rail should be re-positioned and re-hammered or replaced.
3.Maintain proper torque. Proper torque ensures the rail anchor is snug against the base of the rail and can provide the necessary stability and safety.
