Drive-on Rail Anchors And Spring Type Rail Anchor For Rail Fastening

Drive-on rail anchors and spring type rail anchors are indispensable key components in the rail fastening system. Their core function is to form a stable connection between the rail and the sleeper, restrict the longitudinal and lateral displacement of the rail, and ensure the smoothness and safety of the track line. The drive-on rail anchor relies on an integrally stamped and formed structural design, which can be directly pressed into place by special machinery during installation, eliminating cumbersome procedures such as welding and drilling of traditional anchors, and greatly improving construction efficiency, especially suitable for large-scale railway laying projects.

The spring type rail anchor is made of high-toughness spring steel material, which uses the elastic deformation of the spring to absorb the impact load and vibration generated when the train passes, and at the same time offset the thermal expansion and contraction stress caused by the environmental temperature difference of the rail, effectively reducing the frequency of track maintenance. Both products have undergone strict heat treatment and surface anti-corrosion treatment, and can still maintain excellent mechanical properties and corrosion resistance under harsh working conditions such as high temperature, humidity, and salt alkali, with a service life far exceeding the industry average.

Drive-on rail anchors are hammered on for quick, simple installation using friction, ideal for cost-sensitive projects, while Spring-type anchors use elastic force from spring steel, requiring special tools for a more secure, vibration-dampening hold, better suited for high-speed lines needing stability and less rail creep.

The key differences lie in installation (hammer vs. tool), force mechanism (friction vs. spring tension), and application (basic vs. high-performance).

Drive-on Rail Anchors

• Installation: Hammered directly onto the rail base against the tie; quick and manual.

• Mechanism: Simple, rigid design relying on friction to prevent movement.

• Performance: Good for basic needs but can loosen if overdriven.

• Application: Cost-effective, rapid deployment projects.

Spring-Type Rail Anchors

• Installation: Requires specialized tools, making it more complex.

• Mechanism: One-piece spring steel provides constant clamping force, absorbing vibration.

• Performance: More stable, better vibration dampening, and consistent hold.

• Application: High-speed railways, urban transit, or anywhere greater stability is crucial.

1. Rail anchors are always used in steel rails such as 50kg, 85kg, UIC54, UIC60, 90/91lb, 115RE, 136RE, just to name a few. We can produce T or V-shaped rail anchors as well as other types according to clients' requirements, by forging or casting.

2. Generally speaking, based on our former production experience, most common material for rail anchor production is 60Si2MnA, which is often used for rails such as 50kg, 70lb, 80lb, 90/91lb and so on.

3. Rail anchors for Russia market : high grade ductile iron castings

Russian rail anchor is often used in railways by casting, which is made from material of QT400-15. All related mechanical properties of it are strictly following with the standard of TOCT 7293-85.

To ensure the integrity of the product during transportation, the rail anchor adopts multi-layer protective packaging: each set of products is first wrapped independently with anti-rust oil paper to isolate air and moisture; then placed into a hard carton with a custom foam lining, each box holds 20 sets, and the foam lining can fix the product position to prevent collision and friction
