Product Introduction
The SKL fastener system is a key connection device for railway track engineering. It locks the rail firmly on the sleeper through mechanical fastening to ensure the stability of the track geometry. The rail pad is made of high-elastic rubber with good insulation and buffering properties.
In actual applications, SKL1 meets the needs of ordinary railway branches with a simple and practical design; SKL2 improves the fastening effect by increasing the diameter of the spring bar, which is suitable for busy freight lines; SKL3 innovatively adopts a wavy pad design to reduce subway operation noise by 15dB; SKL12 optimizes parameters for the strict requirements of high-speed rail for smoothness; SKL13 has a reinforced reinforced component structure, which is suitable for heavy-duty railway transportation with large axle loads; SKL14's modular design supports rapid assembly and is suitable for temporary railway construction projects; SKL15 accurately matches ballastless track plates to ensure long-term stable connection.
Skl W14 elastic rail clamp fastener system is a fastener system widely used in railway tracks. Components:
Elastic clamp: generally made of 60Si2MnA and other materials, with a surface hardness of 40-46HRC after heat treatment, in the shape of a W. It has two highly elastic, independently acting spring arms that can firmly press the rails, and the curved part in the middle can be used as additional anti-tilt protection. Its high fatigue strength can resist the dynamic vertical movement generated when the vehicle passes over the rails.
Insulating parts: including insulating pads, etc., usually made of materials with good insulation properties, which can prevent current from being transferred from the rails to the sleepers and reduce the impact of stray current on the track structure and surrounding facilities.
Spiral spikes: such as SS35 spiral spikes, commonly used specifications are M24×150mm, M24×160mm, M24×180mm, etc., used to fix the fastener system on the sleepers.
Washers: play the role of buffering and adjusting pressure, so that the force of the fastener system is more uniform.
Rail pads: Made of materials such as EVA, their elasticity compensates for vertical forces and ensures stable deformation of the rails, while also absorbing vibrations and reducing structure-borne noise.
