Products Parameters
RNY spring blade rail fastening system mainly used on the railway project in Mexico and North America , this rail fastening system is suitable for fastening of 115RE steel rail on concrete sleeper.
In comparison to other fastening system, it provides several benefits. It is less expensive since it is less complicated to install and maintain. In addition to reducing noise and vibration, the spring blade technology is crucial for railway lines that pass through residential areas.
Over the world, railway systems employ the spring blade fastening mechanism often. It is especially well-liked in nations with high-speed rail systems, where stability and security are crucial. The spring blade mechanism is intended to be stable and durable over time. This assists in making sure the rails are kept firmly in place, lowering the possibility of accidents and enhancing the overall safety of the railway system.
