Detailed Product Parameters
The RNY spring blade rail fastening system stands as the cornerstone for railway projects across Mexico and North America. Specifically tailored for securing the 115RE steel rail onto concrete sleepers, it exemplifies robust engineering.
Compared to other fastening systems, this offers numerous advantages, notably being more cost-effective due to its simplicity in installation and maintenance. Beyond economic benefits, its spring blade technology is pivotal in diminishing noise and vibrations-a vital feature for railway lines traversing residential locales.
Globally, the spring blade fastening mechanism is a preferred choice for railway systems. Highly favored in regions with high-speed rail networks, where stability and safety are of utmost importance. Designed for lasting stability and endurance, this mechanism ensures rails remain securely anchored, significantly reducing accident risks and boosting the overall railway safety.
