The Nabla Fastening System is an safe and reliable system, most widely used in Europe. It can be used in Tram, LRT, Metro, Main Line and High Speed tracks. The nabla rail fastening system is extensively used on French TGV High-Speed lines.The special shape of the Nabla blade generates a dynamically stable toe load on the rails when the nut is torqued.
The Features of Nabla Clip Rail Fastening System
Reliable fixing performance: Nabla clip rail fastening system can reliably clamp the rail and ensure that the rail is firmly fixed on the sleeper. This helps prevent the rails from moving, deforming or loosening and maintains rail track stability.
Elastic design: Nabla clips are elastic and can adapt to the expansion and contraction of the rails to cope with changes in different seasons and temperature conditions. This helps relieve stress on the rails, reducing stress-induced damage.
Shock absorption and noise reduction effect: The elastic properties of nabla clips can absorb part of the train vibration and noise, improve the comfort of train driving, and reduce track noise.
Relatively easy maintenance: The components of the nabla clip rail fastening system are relatively easy to install and replace, reducing the cost and time of maintenance and repairs. Maintenance crews can quickly replace damaged clips or other components to extend the life of rail tracks.
High strength and durability: Nabla clips are usually made of high-strength spring steel, which has excellent durability and can maintain performance in long-term high-load operations.
