What you should know when use kpo rail clamp fasteners system?
When using a KPO rail clamp fastener system, know that it is a robust, clamp-type system used for securing rails to sleepers or tie plates, suitable for various rail types and heavy-duty applications like crane rails. You should be aware of its components, which include the KPO clamp, screw spikes, and base plates, and understand its function is to maintain rail gauge and alignment while resisting forces from passing trains through high clamping force and elasticity.
Components and function
- Components: A complete KPO system includes the KPO clamp, which can be a specific type like KPO3, KPO5, KPO6, or KPO9; screw spikes; spring washers; and a base plate.
- Function: The system's primary function is to securely fasten the rail to the sleeper, ensuring the correct rail gauge and preventing longitudinal and lateral movement. It does this by providing a high clamping force and can also absorb shock and vibration.
Maintenance and performance
- Maintenance: Proper installation and periodic checks are crucial, as rail clips can experience stress, fatigue, and corrosion over time.
- Performance: Performance depends on factors like the stiffness of the rail pad and the fatigue life of the elastic clip. A lower stiffness rail pad can lead to greater deformation and increased fatigue on the clips, so these factors must be considered together.

Key considerations
High clamping force: KPO systems are known for providing higher clamping forces than some other systems, making them suitable for demanding applications.
Durability and life span: These systems are designed for long duration and high durability, a key feature for heavy rail traffic and crane rails.
Rail compatibility: The KPO system can be designed to accommodate various rail sections, such as UIC54 and UIC60, with base plate sizes varying accordingly.
Materials and standards: The clamps are typically made from steel, and the entire system can be designed to meet various standards, such as European or GOST standards, depending on the application.
Application: The KPO system is widely used globally and is particularly popular for crane rail applications and high-speed passenger lines due to its robustness.
For different applications, there are many types of rail fastening system, such as E-type, SKL-type, Nabla, KPO-type, fast clip fastening system and so on.Every kind of rail fastening system has its own components. For example, E-type fastening system is made up of E-clip, shoulder, rail pad and insulator. Nabla rail fasting is consists of Nabla clip, insulator, screw spike and spring washer.
Rail fastening system is not supplied as a whole set,GNEE RAILWAY RAILWAY can supply fastening parts separately. We supply the baseplate, rail clip, rail spike(dog spike and screw spike), rail bolt, spring washer. You can customize your order with the help of rail fastener professional.
