KPO Rail Fastening System
The KPO Rail Fastening System is a heavy-duty rail fastening solution designed for crane tracks, port terminals, mining railways, and industrial railway systems where high clamping force, lateral stability, and long-term fastening reliability are required. The system typically consists of KPO rail clamps (such as KPO3 and KPO6), HS T-head bolts, double-coil spring washers, ribbed baseplates, screw spikes, and resilient rail pads, providing secure rail restraint under heavy loads, vibration, and demanding operating conditions.

Designed in accordance with applicable DIN and UIC standards, KPO fastening systems can be configured for rail profiles such as UIC54, UIC60, and various crane rail sections, with fastening arrangements adapted to concrete, timber, or steel sleepers. The rigid clamp design helps maintain rail alignment and gauge stability while reducing rail tilting, longitudinal movement, and fastening loosening during heavy-duty operation.

Difference of Between KPO Fasteners System And SKL Railway Fastening System
The KPO Rail Fastening System and SKL Railway Fastening System use different fastening principles and are designed for different track requirements. KPO is a rigid clamp-and-bolt system focused on high clamping force and strong mechanical restraint, while SKL uses an elastic tension clamp to provide resilient rail fastening and better accommodation of dynamic loads.
| Feature | KPO Fastening System | SKL Railway Fastening System |
| Fastening Type | Rigid clamp-and-bolt system | Elastic tension clamp system |
| Main Component | KPO3, KPO5, KPO6, KPO9 clamps | SKL12, SKL14, SKL21 tension clips |
| Typical Applications | Crane rails, ports, mining and industrial tracks | Mainline, high-speed, metro and urban rail |
| Clamping Principle | High clamping force through bolted KPO clamps | Elastic spring force through tension clips |
| Baseplate | Typically uses ribbed steel/cast-iron baseplates | Direct fastening or baseplate configurations depending on system |
| Main Advantage | Strong rail restraint and high lateral resistance | Elasticity, dynamic performance and fatigue resistance |
| Maintenance | Requires inspection of bolts and fastening components | Generally lower routine maintenance when correctly installed |
Which System Should You Choose?
- Choose KPO when your project requires high clamping force, rigid rail restraint and robust baseplate construction, particularly for crane tracks, port terminals, mining railways and heavy-duty industrial tracks.
- Choose SKL when your project prioritizes elastic rail restraint, dynamic load management and long-term fatigue performance, particularly for mainline, high-speed, metro and concrete-track applications.
The final selection should be based on the rail profile, sleeper type, axle load, operating speed, track structure and applicable standards.

FAQ
Q1: What components are included in a KPO rail fastening assembly?
A: A standard KPO assembly typically includes KPO clamps, HS T-head bolts and nuts, double-coil spring washers, ribbed baseplates, sleeper screw spikes, plastic dowels, and resilient rail pads. The exact configuration depends on the rail profile and project requirements.
Q2: Why is KPO used for crane rails and heavy-duty tracks?
A: KPO provides high clamping force and strong lateral rail restraint, making it suitable for crane tracks, ports, mining railways, and heavy-duty industrial tracks exposed to high wheel loads and lateral forces.
Q3: Can KPO fastening systems provide gauge adjustment?
A: Yes. Depending on the baseplate and clamp configuration, KPO systems can provide lateral adjustment for rail alignment and gauge control.
Q4: How does KPO help prevent bolt loosening?
A: Double-coil spring washers help maintain bolt preload and improve resistance to loosening caused by vibration and cyclic loading when the fastening system is correctly installed and tightened.
