Spring blade fastening system for concrete sleeper

In Mexico and many other countries, concrete sleepers are fastened to railroad rails using a mechanism called the spring blade fastening system. Metal blades with spring-mounted attachments are used in this process. The rails are intended to be held in place and kept in place by the blades. NY-ES, NY-GN, RNY, NY type “e”, and GANY series are the main types of spring blade fastening systems.

In comparison to other fastening techniques, this technique 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.
