SKL Rail Clips Railway Fasteners China

Description and Function

The primary function of SKL rail clips is to provide a high, permanent toe load on the rail, which prevents the rail from moving, bending, or warping under the dynamic stresses of passing trains. 

• Elasticity: Made of spring steel (e.g., 60Si2Cr, 55SiMn, 38Si7), the clips offer elasticity and shock absorption, which helps dampen vibrations and impact when a vehicle passes by.

• Secure Fastening: SKL clips are typically part of a complete system that includes guide plates, rail pads, screw spikes, and plastic dowels. The entire assembly ensures a secure, insulated connection and transfers lateral loads to the sleeper.

• Creep and Twist Resistance: The design ensures excellent resistance to rail creep (longitudinal movement) and twisting, which is essential for continuously welded tracks.

• Versatility: These systems are widely used globally in various applications, including standard track, heavy haul, and high-speed railways, for both ballasted and ballastless tracks. 

Common Types

• SKL rail clips come in various sizes and types, which are designed to meet different international standards and rail profiles. 

• SKL1: A specific type used in various applications.

• SKL3: Another common variant.

• SKL12: Often used in ballastless track systems and popular in Europe and Malaysia.

• SKL14: The most widely used type in many regions, including the CIS, Asia, the Middle East, South America, and Europe.

• SKL21: Used in regions like South America and Africa.

• SKL75: Another specialized variant. 

Applications

• SKL Rail Clips are widely used in heavy-duty rail applications, including high-speed lines, heavy freight lines, and other track systems where stability and longevity are critical.

• They are commonly paired with SKL fasteners, including baseplates, rail pads, and other components of the rail fastening system.
