Products Parameters
The NY-ES spring blade rail fastening system is predominantly deployed in railway projects throughout Mexico and North America. This highly efficient system is optimized for securing the 115RE steel rail on concrete sleepers, ensuring robust performance.
Compared to other fastening systems, it offers numerous advantages, as it is more cost-effective due to its straightforward installation and maintenance. Moreover, the innovative spring blade technology significantly minimizes noise and vibration, which is particularly beneficial for railway lines traversing residential areas.
Globally, railway networks frequently utilize the spring blade fastening mechanism. It is particularly favored in countries with advanced high-speed rail systems, where stability and security are paramount. The robust design of the spring blade mechanism ensures enduring stability, helping maintain rails securely, thus reducing accident risks and boosting the overall safety of the railway infrastructure.
