Product Introduction
The SKL fastener system is a set of special components for railway tracks that achieve reliable connection through precision mechanical structures. It is composed of spring bars, rail pads, gauge baffles and other components. It is mainly used to firmly fix the rails on the sleepers to ensure the stability and safety of the track structure when the train is running, and effectively disperse and buffer the wheel-rail force. The system uses high-strength spring steel, high-performance rubber and other high-quality materials, and is manufactured through advanced technology. It has high buckle pressure, strong fatigue resistance and good environmental adaptability. It can operate stably under different climatic conditions such as severe cold, high temperature, high humidity, and various line conditions such as high-speed railways, heavy-load railways, and urban rail transit.
According to different design parameters and application requirements, the SKL fastener system is divided into multiple models:
▇ SKL1 is the basic model, suitable for ordinary railway branches, and is known for its stable buckle pressure and basic shock absorption function;
▇ SKL2 enhances the clamping force on the rail by optimizing the curvature of the spring bar, and is often used in freight railways to cope with the pressure caused by large axle loads;
▇ SKL3 adopts a double spring bar structure, which improves elasticity and buffering performance, and is more suitable for lines with high noise reduction requirements such as urban subways;

▇ SKL12 is a special model designed for high-speed railways, with higher initial buckle pressure and fatigue resistance, and can adapt to the dynamic load of trains running at high speeds;
▇ SKL13 is developed for heavy-duty railways, and its components are thickened and strengthened to withstand frequent rolling by trains with an axle load of more than 30 tons;
▇ SKL15 is suitable for ballastless track plates, and through a unique embedded casing structure, it can achieve a close combination with the track plate to ensure the long-term stability of the track geometry.
