The SKL clip rail fastening system is widely used for both ballasted tracks and concrete sleepers. Known for its reliable operation, minimal wear, and low maintenance requirements, the SKL system provides a high-elasticity solution for conventional and heavy-load railways due to its high toe load, dynamic fatigue strength, and resistance to rail creep.
The design of SKL clip system ensures durability and stability under varying operational conditions, making it suitable for diverse rail environments. Its effectiveness in handling high loads and dynamic stresses enhances overall track performance and longevity This clip system's simple structure facilitates easy installation and maintenance, contributing to its widespread adoption around the world, with notable use in Europe, Central Asia, the Middle East, and Southeast Asia.
