Product Introduction
SKL Type Railway Fastening System is a complex and precise railway track fastening system, which consists of spiral spikes, flat washers, spring bars, rail pads and other components. According to different sleeper materials (such as concrete sleepers, wooden sleepers), the railway fastener system can adapt to the corresponding installation combination scheme. On mountain railways, it can resist the influence of settlement and displacement caused by complex terrain, ensuring that the rails are always in the correct gauge and horizontal state; on coastal railways, the anti-corrosion materials and processes used can effectively resist salt spray erosion, extend the service life of fasteners, and ensure the safety and stability of the track structure in harsh environments.
SKL Type Railway Fastening System mainly consists of several key components.
Spiral spike: also known as tirefond or sleeper screw, known as wood screw in the United States. It is used to fasten the base plate and rail to the wooden sleeper, and can also be used to fix the rail indirectly or directly on concrete and wooden sleepers.
Spiral pin: usually made of HDPE or PA 66 material, pressed into the concrete sleeper and used in conjunction with the spiral spike.
SKL tension clamp: It is an important component in the system that directly acts on the rail to achieve the fastening function. Its design and performance directly affect the fixing effect of the rail.
Guide plate: also known as insulator, the shape is different from the E-clip insulator (GPI), and it is often called an angle guide plate. It is located below the tension clamp and is used to maintain the lateral position of the rail. The lateral force generated by the train running is transmitted to the concrete sleeper through the guide plate. Common models include WFP 14 K 14.5, WFP 14 K 12, etc.
Rail pads: They act as buffers and shock absorbers under the rails, reduce the impact of train operation on the track structure, and protect the rails and sleepers.
A complete set of SKL Type Railway Fastening System generally includes 4 spiral spikes, 4 spiral pins, 4 SKL tension clamps, 4 guide plates, and 2 rail pads.
