Each comprehensive set of our RNY system is a testament to precision engineering and includes 4 pieces of SL bolts, 4 RNY elastic plates, 4 square elastic plates, 4 cylindrical cushions, 4 NY nylon washers, 4 flat washers, 4 nuts, and 2 rail pad U-2. This ensemble ensures robust rail track stability.
Products Parameters
The RNY Spring Blade Rail Fastening System is the backbone of railway projects across Mexico and North America. This innovative system is engineered specifically for the secure fastening of the 115RE steel rail onto concrete sleepers, enhancing the safety and longevity of rail infrastructure.
Compared to conventional fastening systems, this system stands out with its impressive array of advantages. It is more cost-effective, as it demands less effort for installation and maintenance. Beyond its economic benefits, the spring blade technology plays a pivotal role in diminishing noise and vibration, making it an indispensable choice for railway lines traversing residential areas.
Globally, the innovative spring blade fastening mechanism is a staple in railway systems. Its popularity is particularly pronounced in countries with high-speed rail networks, where utmost stability and security are paramount. The design of the spring blade mechanism ensures steadfast stability and longevity, which is critical for maintaining the integrity of rail tracks, thereby minimizing accident risks and significantly bolstering overall railway safety.
