The railway anchor is a spring steel clip fixed on the lower side of the steel rail and leaning against the side of the railway sleeper, which is mainly used to prevent longitudinal movement of the rail track. The longitudinal movement of the rail track is mainly caused by the inertial force when the train is running or stopping, or the creep caused by the rail track temperature or rail track gradient change.
The rail anchor has an important auxiliary role for the railway track support system. It increases the contact area between steel rails and railroad sleepers, reduces the cutting and wear of steel rails on railway sleepers and railway foundations, and improves the service life of the entire railway. The size, shape and hardness of the railway anchor are mainly determined by the weight of the rail track and the width of the railway foundation. Rail anchors are generally divided into: drive-on rail anchor and spring rail anchor.
How to install rail anchor correctly? Regarding the application of rail anchor, generally follow the following rules:
1. The rail anchor should be located on the rail gauge side of the railway base and opposite to the same rail gauge tie rod face on the opposite rail track.
2. The railorad anchor must firmly fix the track base and fully support the rail track contact surface.
3. When the rail anchor's support to the rail gauge tie rod is disturbed, a new rail anchor and a rail tie plates will be required.
4. The railroad anchor should not be moved by driving along the rail track.
5. When applying irion railroad anchor, keep the rail track straight.

Raw materials for rail anchor:
1. The most common material used to produce rail anchors is 60Si2MnA, which is usually used for 50kg, 70lb, 80lb, 90/91lb rails.
2. The iron rail anchor for the Russian market is high-grade ductile iron castings. The Russian railway anchors produced by Kingrail are usually made of QT400-15 material, and all its related mechanical properties can reach the Russian TOCT 7293-85 standard.
The production process of rail anchor:
1. The shape of the rail anchor in each country is different, such as improved fairness, V-shape or groove shape.
2. The rail anchor is usually a one-piece metal made of spring steel by rolling, forging or casting after heat treatment. Railroad anchors with complicated bending are usually produced by casting.
We can produce rail anchors according to the drawings and technical requirements or the sample you sended to us.
