Introducing the RNY Rail Fastening System: a true game-changer in rail infrastructure. This innovative system is expertly designed for the 115RE rail, with a primary application across the vibrant landscapes of South America and Latin America.
Each comprehensive set features a meticulously crafted assembly: 4 SL bolts, 4 RNY elastic plates, 4 square elastic plates, 4 cylindrical cushions, 4 NY nylon washers, 4 flat washers, 4 nuts, and the robust 2-piece rail pad U-2, ensuring unmatched durability.
Product Parameters: A testament to precision engineering.
The RNY spring blade rail fastening system is the cornerstone of railway projects throughout Mexico and North America. Tailored for securely fastening the 115RE steel rail onto concrete sleepers, it epitomizes reliability and strength.
Distinguishing itself from conventional systems, our solution offers an array of unparalleled advantages: it is remarkably cost-effective, owing to its simplified installation and maintenance. The inclusion of spring blade technology not only enhances ease of use but plays a pivotal role in mitigating noise and vibration, which is especially critical for railway lines weaving through bustling residential areas.
Globally, the spring blade fastening mechanism is a staple in railway systems. It is especially revered in nations boasting high-speed rail, where unwavering stability and safety are non-negotiable. Designed for enduring stability, the mechanism ensures rails are anchored securely, significantly reducing accident risks and bolstering railway safety.
