Rail anchors,also called anticreepers, are used in the fastenings system for creep resistance function.They are made of spring steel with elasticity that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration, prolonging the life of rail ties.Rail anchors grisps the steel rail during the train running through the steel rail.
Rail anchors transmit static and dynamic longitudinal forces in the rail to the cross tie. A sufficient number of anchors are required to hold the rail in a fixed position.

For heavy rail tracks such as 50kg, 70lb, 80lb, 90/91lb, best option for steel material is 60Si2MnA, based on our former production experience and customer feed back, this material shows more stable mechanical property than most common material for rail anchor production is 60Si2MnA.
| Type | Material | Weight(g/pc) |
| 50Kg | 60Si2MnA | 800 |
| 70LB | 60Si2MnA | 800 |
| 85LB | 60Si2MnA | 800 |
| 90/91LB | 60Si2MnA | 800 |
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.
