Product Description

Main uses
Fix the position of the steel rail
Precisely maintain the gauge, level and direction of the rails to ensure the stability of the track geometry.
Adapt to the operational requirements of high-speed railways with large axle loads and high speeds (250-350km/h).
2. Provide elastic buffering
The impact and vibration of train wheel-rail are attenuated through elastic elements such as rubber pads, noise is reduced, and the track structure and subgrade are protected.
3. Insulation protection
It is designed with insulating materials to prevent short circuits in the track circuit and ensure the normal operation of the signal system.
4. Adjustment ability
It is allowed to make slight adjustments to the gauge and rail surface height through gaskets to adapt to the construction errors of the track and long-term settlement.

 

Typical usage scenarios
Ballastless track system
Designed specifically for CRTS type I/II/III slab ballastless track, it is commonly used in high-speed railway trunk lines (such as Beijing-Shanghai, Beijing-Guangzhou, etc.) and intercity railways.
2. Elevated bridge and tunnel sections
Due to its high demand for elasticity, it is often used in rigid foundation sections such as Bridges and tunnels to alleviate vibration transmission.
3. Extremely cold and hot regions
It has strong weather resistance and can adapt to environments ranging from -40ºC to +60ºC, making it suitable for extreme climate regions such as Northeast and Northwest China.
4. Passenger dedicated lines
It is prioritized for high-speed railway lines mainly for passenger transport, taking into account both comfort and durability.

 

Technical characteristics
Double elasticity: Rubber cushion layers are set both under the rail and under the iron pad plate, achieving a remarkable vibration reduction effect.
Anti-loosening design: The bolt anti-loosening structure ensures the reliability of fastening under long-term high-frequency vibration.
Low maintenance: The modular design facilitates quick replacement and reduces operation and maintenance costs.

 

The WJ-8 fastener is a core component of the ballastless track of China's high-speed rail. It ensures the safe and stable operation of high-speed trains through high elasticity, high precision and strong adaptability, and is especially suitable for passenger dedicated lines with a designed speed of more than 300km/h and complex geological environments.
