Railway SKL3 Tension Clamp

The SKL railway fastener system is a standardized connection system developed to improve the stability and safety of railway tracks. Its importance is particularly prominent in high-speed passenger railways and busy freight railway scenarios. It has the advantages of simple structure and convenient installation, which greatly shortens the construction period and reduces construction costs. In terms of classification, the SKL railway fastener system can be divided into SKL system for ordinary ballasted tracks and SKL system for ballastless tracks according to the type of track used. Different types differ in design details and material selection to adapt to the characteristics of their respective tracks.

SKL3 spring bars are usually bow-shaped with hooks at both ends for buckling rails, and the middle part is in contact with the sleeper or pad. This structural design enables the spring bar to provide elastic force and buckling pressure through its own bending and torsional deformation when subjected to external forces. It is generally made of high-quality spring steel such as 60Si2Mn, 60Si2Cr, 38Si7, etc. These materials have high strength, high elastic limit and good toughness, and can withstand the repeated alternating stress caused by train loads, ensuring the reliability and stability of the spring bar during long-term use.

For small precision railway fasteners, plastic compartmented turnover box packaging is the mainstream choice. The turnover box is equipped with a removable plastic partition, which can flexibly divide the independent space according to the size of the fastener, and the bottom of each grid is covered with an anti-static sponge pad. After placing the fasteners in the corresponding grid, cover the box with a sealing strip to prevent dust and moisture from invading. When multiple turnover boxes are stacked, plastic corner guards are added to the corners of the box, and then tightly wrapped with stretch film to ensure that the stacking is stable and convenient for railway freight loading and unloading.
