Rail Anchors and Rails
Rail anchors are used to clip onto the rail base, snugly against the sleepers on both sides. It is made from spring steel in one piece and is designed to eliminate rail slippage or expansion or contraction.
How do Rail Anchors Work?
The rail anchors are installed directly on the rail base and rest on the sleepers, they are used to fix the rail to the base plate and the sleepers, it is designed with one-piece construction to prevent the rail from moving longitudinally, such as "crawl" by temperature, slope, traffic Rail failures caused by changes in mode and train braking action.
Provides a large bearing surface for the rail base and sleeper to prevent cutting and wear, thereby extending the service life of the sleeper. Rail anchors are manufactured for a specific rail weight and base width and can be divided into two types: driven rail anchors and spring-loaded rail anchors.
Rail Anchor Installation Guide:
How to use rail anchors? General rules for the application of rail anchors:
1. The rail anchor bolts should be located on the gauge side of the rail base against the same connecting surface on the opposite rail.
2. The rail anchors must hold the rail base tightly and securely and fully support the sleeper face.
3. When the support of the rail anchor to the sleeper is disturbed, a new rail anchor and sleeper will be required.
4. Do not move the anchor by driving it along the track.
5. When using the anchor, keep the sleeper straight.
The installation position of the railway anchor:
Typically, rail anchors are used in the following rail locations.
When using bolts, taking a 39-foot rail as an example, 8 rail bolts are generally recommended, as shown in the figure below. The number of anchors may increase as the steep slope increases.
On the open Baker Bridge. Anchors are used on rails close to exposed deck bridges, and every third tie should be box anchored at least two rail lengths from both ends of the bridge.
At the railroad crossing. For railway crossings using bolts, every three sleepers shall be box anchored at least two rail lengths in all directions from the crossing.
Railway turnout. Anchors are optional and are used for turnouts. Helps correct geometry issues when using anchors in turnouts.
