Product Info - KA-Clip Rail Fastening

KA-Clip Rail Fastening

Supply record of KA-Clip in Indonesia ? 468.34 km track.

Design features of The KA-Clip
? Few and simple components
? Easy of installation
? Effectively reusable when changing the rail
? Virtually no maintenance requirements
? High Clamping force 750 ? 1300 Kgf
? (According to National Standard Indonesia SNI 11-3677-1995)
? Elastic fastening which continuous to grip the rail under vibration
? Capable to counteract longitudinal and lateral loads
? Capable to counteract axle load
? Self locking anti vandal
? Can be used for straight, curve and cross tracks as well as rail joints
? Can be used for any type of rail
? Equipped with electrical insulator to protect the signal and tracking systems.
? The fastening of the KA-Clip system is reusable for upgrading rail or replacing timber, steel or concrete ties
