KPO Fastening System | One Stop Supplier

The KPO fastening system is a heavy-duty, bolt-and-clamp rail attachment system that provides a rigid and durable connection for industrial tracks. Unlike the elastic spring clips of the Pandrol system, the KPO system uses a clamping plate (the KPO clip) tightened by a nut and bolt to lock the rail firmly against a baseplate.

Signum Rail Fastening offers rail fasteners for KPO systems, providing comprehensive one-stop services.

Primary Components

A complete KPO assembly for a single sleeper typically includes the following components:

• KPO Clamp (Clip): Available in various sizes (KPO3, KPO6, KPO9) to match different rail profiles.

• Baseplate (Ribbed Tie Plate): A canted plate that supports the rail and contains the "ribs" where the clamp sits.

• T-Bolt or HS Bolt: Used to secure the KPO clamp to the baseplate.

• Screw Spike: Used to fasten the entire baseplate assembly to timber or concrete sleepers (often paired with a plastic dowel for concrete).

• Double Coil Spring Washer: Maintains tension on the nut to prevent loosening due to vibration.

Key Performance Advantages

The KPO system is highly regarded in specific industrial sectors due to its robust design:

• Superior Clamping Force: The rigid bolt-tightened clamp offers stronger resistance to track movement than many elastic systems.

• Durability in Harsh Environments: It is specifically engineered to handle the extreme loads found in port transportation, mining tracks, and crane rail systems.

• Modular Versatility: The system is compatible with a wide range of rail profiles, including UIC54, UIC60, and various heavy-duty crane rails.
