What are the applications of Pandrol clips in railways?
Rail clip, also called elastic rail clip, it is used to fasten the rail tracks with railroad spike, rail pad, track bolt, rail joint bar together. It is also usually used as a part of rail fastening system. There are huge demand of rail clips on the railway line, about 7000pcs per kilometer, which is directly related to rail safety.
Pandrol clips are used in railways as a fastening system to secure rails to the foundation, with applications in various rail types and infrastructure, including high-speed, heavy haul, and urban transit lines. Their main functions are to provide durable and reliable rail fixation, control noise and vibration, and reduce track maintenance requirements and installation time.
Key applications
- Securing rails: The primary application is to firmly fasten rails to sleepers (both concrete and timber) and to slabtrack, ensuring the stability and safety of the track.
- Vibration and noise control: Pandrol systems are engineered to reduce the transmission of noise and vibration, which is crucial for passenger comfort and for minimizing structural impact in urban and tunnel environments.
- Different track types: They are used across a wide range of rail infrastructure, including:
High-speed passenger lines
Heavy haul and mineral railways
Urban and rapid transit systems
Ballasted and ballastless track systems
Specialized applications like ports, depots, and turnouts
- Maintenance and efficiency:
The system is designed for long life and can be dismantled for inspection and maintenance, with replaceable parts.
Some systems, like the Fastclip, can be pre-assembled and installed mechanically, which speeds up installation and reduces labor costs.
They can incorporate features for track gauge adjustment, which is beneficial for maintenance and correction.
