Product Introduction
SKL12 spring rail fastening system is a highly standardized fastener device in railway track engineering. Its main features are simple structure, easy installation and reliable performance. The system consists of standard components such as spring bars, gauge blocks, insulating pads and fastening bolts, and the components are connected by mechanical matching.
The spring bars are made of high-quality alloy steel through special processes and have stable elastic properties and anti-fatigue characteristics. The gauge block is made of reinforced nylon material, which not only ensures the insulation requirements but also has sufficient mechanical strength. The whole system is designed with scientific mechanics to evenly distribute the buckle pressure at the bottom of the rail, effectively preventing rail creep and gauge changes. The system is suitable for all kinds of concrete sleepers. Only conventional tools are needed for installation, which greatly improves the construction efficiency. It is one of the standard fasteners widely used in railway track construction.
