Product Introduction
As an indispensable part of railway tracks, railway fastener systems maintain the geometry of the track by tightly connecting the rails to the sleepers, ensuring the safe operation of the train. According to the installation method, it can be divided into pre-embedded, post-installed and quick-installed types. For example, the pre-embedded WJ-8 type fastener is embedded in the casing when the concrete sleepers are prefabricated. It has high installation accuracy and good stability, and is suitable for high-standard lines such as high-speed railways;
In terms of material selection, the spring bar uses high-strength alloy steel to ensure the buckling pressure, and the pad uses rubber or composite materials to achieve vibration reduction and insulation. These systems effectively improve the smoothness and stability of the track, reduce the resistance of train operation, and improve transportation efficiency.
SKL fastener system: It is also used in some high-speed lines of urban rail transit. Its spring bars have a certain elasticity, which can buffer the vibration and impact force generated by train operation to a certain extent and maintain the stability of the rails. The structure is simple and reliable, easy to install and maintain, and can adapt to certain changes in line conditions. For urban rail transit express lines with low speed, it can meet the track stability requirements.
WJ-8 fastener system
High speed adaptability: It is specially designed for high-speed railway ballastless track, which can meet the operation requirements of high-speed railway with speed level of 350km/h and below, can withstand the huge load of high-speed trains, and ensure the position accuracy and stability of rails under high-speed operation.
Reliable insulation performance: Engineering plastic insulation blocks are set between the iron pad shoulder and the rail, which greatly improves the insulation performance of the fastener system, especially the insulation resistance during rainfall, ensures the normal operation of the track circuit, and provides reliable guarantee for the signal transmission and control of high-speed trains.
Strong structural stability: The lateral load of the train is transmitted to the concrete shoulder through the iron pad and the gauge baffle, which reduces the position of the lateral load, makes the structure more stable, and can effectively resist the lateral force generated by the high-speed train during operation, ensuring the lateral stability of the rail.

Product Packaging & Delivery
A canvas packaging bag with a telescopic bracket is designed. Multiple compartmentalized pockets are set inside the bag, and each pocket is equipped with a Velcro closure. After the fasteners are classified and put into the pockets, the telescopic brackets around the bag are pulled out to keep the packaging bag in a three-dimensional shape and prevent squeezing. The bag opening is tied with a drawstring and equipped with a metal lock. A wear-resistant pad is installed at the bottom of the packaging bag, which can be placed independently or stacked. It is suitable for temporary turnover and transportation of fasteners in scenes such as construction sites.
