Product Introduction
As a basic component of track engineering, the design of the SKL12 spring clip rail fastening system fully considers the actual needs of railway operations. The system adopts a modular structure, mainly including three specifications of spring clips (according to different buckle pressure requirements), adjustable gauge blocks, weather-resistant insulation components, etc.
The spring clips undergo a heat treatment process to ensure stable elastic performance during long-term use; the gauge block provides a gauge adjustment range of ±8mm for easy line maintenance; the insulation components are made of high-strength engineering plastics, which not only ensure electrical insulation performance, but also have sufficient mechanical strength. The system achieves standardized fastening force through torque control during installation, so that each fastener node can meet the design requirements. After years of engineering practice verification, the fastening system can maintain stable performance for more than 10 years under normal operating conditions, which is an important guarantee for the safe operation of railway tracks.
The main components of the SKL12 fastener system include:
SKL spring bar: provides elastic buckle pressure, used to fasten the rails, commonly used materials are 60Si2CrA, 38Si7, etc.
Gauge plate: also known as angle plate, usually made of Q235 and other steel materials, used to adjust and maintain the gauge
Rail pad: generally made of EVA, rubber or HDPE and other materials, with good elasticity and vibration reduction performance
Bolt: mostly made of Q235, 45# steel, etc., used to connect and fix various components
Nut: used in conjunction with bolts, the material and grade match the bolts to ensure the tightness of the connection.
Washer: Flat washers are generally made of Q235 steel, used to increase the contact area and disperse the pressure
