Product Introduction
The SKL fastener system is a standardized rail connection device developed based on the actual needs of railway engineering. It consists of spring bars, pads, gauge baffles and other components. Through scientific and reasonable mechanical structure design, it realizes reliable connection between rails and sleepers, effectively disperses train loads, and maintains stable track geometry. The system adopts advanced heat treatment processes and surface protection technologies to make core components have high strength, high toughness and strong corrosion resistance.
In terms of model classification, SKL1 is simple and reliable and suitable for ordinary railway branch line maintenance; SKL2 meets the needs of medium-capacity regional railway trunk lines by improving the performance of spring bars; SKL3 plays an important role in subways and other lines with high environmental requirements with its unique vibration reduction structure design; SKL12 is optimized for high-speed railways to ensure the smoothness of the track during high-speed train operation; SKL13 reinforced configuration is specially designed for heavy-duty railways and can withstand the impact of super-large axle-load trains; SKL15 is adapted to the special installation method of ballastless track to achieve high-precision and high-stability connection.
SKL12 Fasteners System
Spring bars: 2 pieces, which are key components of the SKL12 fastener system, provide buckling pressure and elasticity, and are generally made of spring steel such as 60Si2MnA and 60Si2CrA.
Rail pads: 2 pieces, usually 199mm×158mm×6mm, used to buffer the pressure between the rails and the sleepers, and the materials are mostly EVA, etc.
Threaded spikes: 4 pieces, with specifications of M24×150mm, M24×160mm, M24×180mm, etc., used to fix the fasteners on the sleepers or track plates.
Plastic sleeves: 4 pieces, pre-buried in the sleepers or track plates, used in conjunction with threaded spikes, to play a role in fastening and insulation.
Insulating gaskets: Several, used to increase insulation performance and prevent current from being transmitted to the sleepers through the rails.
Washers: 4, generally 25mm×25mm×3.5mm, used with threaded spikes to increase the contact area between the nut and the sleeper and prevent the nut from loosening.
Gauge block: configured as needed to adjust and maintain the gauge of the rail.
Iron plate: Some SKL12 fastener systems may include iron plates to enhance the overall structural strength and stability of the fastener.
Product Application
Product Packaging & Delivery
For heavy or valuable fasteners, wooden box packaging provides stronger protection. First, wrap the fasteners with moisture-proof paper or plastic film, and then put them into a customized solid wooden box or plywood box. The gaps in the box are filled with dry sawdust or foam board to play a buffering and moisture-proof role. The outside of the wooden box is reinforced with iron bars, and the box cover is locked with bolts or buckles to ensure that the parts will not be damaged due to squeezing or collision during transportation.
