E-type railway fastener system
The E-type railway fastener system is an indispensable elastic connection device for railway tracks. Its core E-type spring clip is made of high-quality spring steel (60Si2MnA/60Si2CrA) by forging, and provides stable, lasting buckle pressure.
The system ensures precise rail positioning through scientific mechanical-structure design:
- the E-type spring clip works with the rigid limit of the rail shoulder to control the lateral displacement of the rail within a very small range;
- the HDPE rail pad absorbs vibration energy through deformation and reduces the stress of the track structure;
- the rail insulation parts are made of specially formulated reinforced nylon (PA66), wear-resistant with excellent insulation properties.
The system includes spring-clip specifications such as E1609 and E2009, flexibly selected according to rail type and axle weight. The E16, E18 and E20 clips are different diameter specifications in the E-type system (16 mm, 18 mm and 20 mm bar diameters), with corresponding buckle pressure families of approximately 500–700 kgf (4.9–6.9 kN), 750–900 kgf (7.4–8.8 kN) and 1100–1400 kgf (10.8–13.7 kN). All models provide reliable rail fixation, elasticity to absorb impact energy (shock-absorbing, reducing rigid collision between rail and sleeper) and good fatigue performance for long-term high-frequency train operation.
E16, E18, E20 Elastic Clip Fastening System
The E-type railway fastener system is an indispensable elastic connection device for railway tracks. Its core E-type spring clip is made of high-quality spring steel and provides stable, lasting buckle pressure. The E16, E18 and E20 clips are the 16 mm, 18 mm and 20 mm diameter specifications within the E-type system.
1. System Design
The E-type fastening system is a standardised solution for precise rail positioning. The E-type spring clips are formed by forging technology; with the rigid limit of the rail shoulder, the lateral displacement of the rail can be controlled within a very small range. The HDPE rail pad absorbs vibration energy through deformation and reduces the stress of the track structure. The rail insulation parts are made of specially formulated reinforced nylon (PA66), wear-resistant and with excellent insulation properties, preventing short circuits in the track circuit.
2. Clip Diameters and Buckle Pressure
| Clip | Bar diameter | Buckle pressure (kgf) | Buckle pressure (kN) |
|---|---|---|---|
| E16 | 16 mm | 500–700 | 4.9–6.9 |
| E18 | 18 mm | 750–900 | 7.4–8.8 |
| E20 | 20 mm | 1100–1400 | 10.8–13.7 |
3. Key Performance
- Clamping force: different models provide different clamping forces to ensure the rails are reliably fixed on the sleepers.
- Elasticity: all models have a certain elasticity to absorb the impact energy generated by train operation, providing a shock-absorbing effect and reducing rigid collision between the rails and the sleepers.
- Fatigue performance: all models meet the requirements of long-term high-frequency train operation with good fatigue performance.
4. Series Selection
The system includes spring-clip specifications such as E1609 and E2009, flexibly selected according to rail type, train axle weight and required buckle pressure. Suitable rails include UIC54, UIC60, 115RE, BS80 lbs, BS100 lbs, 50 kg and 60 kg rails.
