Product Description

Main uses
Fix the position of the steel rail
Ensure that the rails are stably fixed on the sleepers or track plates to prevent lateral displacement (maintaining the gauge) and longitudinal crawling.
Control the height, level and direction of the rails to ensure the smooth operation of the train.
2. Buffer the impact of wheel-rail
The vibration of the train is absorbed through rubber pads, elastic layers, etc., the noise is reduced, and the service life of the track and the vehicle is prolonged.
3. Adapt to temperature changes and track deformations
Allow the rails to undergo slight displacement due to thermal expansion and contraction to prevent track deformation caused by stress concentration.
4. Electrical insulation (Electrified Railway)
Insulating materials (such as nylon gaskets) are adopted to prevent short circuits in the track circuit and ensure the normal operation of the signal system.
5. Adjust the geometric parameters of the orbit
The height and gauge of the rail are fine-tuned by adjusting plates, spiral spikes, etc., to compensate for construction errors or foundation settlement.

 

Common usage scenarios
High-speed railway (ballastless track)
Fastener types: WJ-7, WJ-8, Vossloh 300, etc
Features: High elasticity and high precision, suitable for lines with a speed of 350km/h and above, such as the Beijing-Shanghai High-Speed Railway and the Beijing-Guangzhou High-Speed Railway.
Function: Reduce vibration, improve smoothness, and ensure the stability of the train during high-speed operation.
2. Conventional railway (ballasted track)
Fastener types: Elastic bar Type I, Type II, Type III
Features: Simple structure, economical and durable, suitable for mixed passenger and freight routes with a speed of 120-160km/h.
Function: It provides basic fixation and buffering, adapting to larger axle loads and frequent train loads.
3. Heavy-haul Railway (Large axle load freight transportation)
Fastener type: Reinforced elastic bar fastener
Features: Strong resistance to lateral force, good anti-loosening performance, suitable for freight dedicated lines such as the Daqin Railway.
Function: To withstand greater wheel-rail impact, prevent rail crawling or loosening of fasteners.
4. Urban Rail Transit (Metro/Light rail)
Fastener type: DT series, Nabla fasteners
Features: High requirements for vibration and noise reduction, suitable for underground tunnels and elevated bridge sections.
Function: To reduce the vibration and noise impact of train operation on the surrounding environment.

 

Railway fastener panels are key components in the track system used to fix rails. Their main functions include maintaining the gauge, providing elastic cushioning, adjusting the geometric dimensions of the track, and adapting to the operational requirements of different lines.

 

Railway fastener panels are the core components of the track system, directly affecting the safety and comfort of train operation. Appropriate types of fasteners should be selected for different lines (high-speed rail, conventional speed, heavy-load, and metro) to ensure long-term stability and maintenance economy.
