The Advantages Of The Nabla Rail Clip

Sep 03, 2025 Leave a message

The buckle of the railway fastener is mainly manufactured using a spring steel, which is bent and twisted by the elastic strip to generate a buckle pressure acting on the rail,the name is elastic rail clip or rail clips.

 

It effectively ensuring a reliable connection between the steel rails and rail sleepers for a long time, maintaining the integrity of the rail as much as possible, and preventing the rail from longitudinal and lateral movement relative to the rail sleeper, the gauge distance is ensured to ensure the safety of the train.

The Advantages of the Nabla Rail Clip

 

rail fasteners

 

(1) The system is compatible with all rail types, including vignole, grooved, AREMA, and industrial rails.

 

(2) The Nabla rail elastic clip is easy to install, reducing both time and cost.

 

(3) Made of glass-reinforced material, it provides high mechanical strength and absorbs lateral forces effectively.

 

(4) Nabla Evolution delivers higher electrical insulation than comparable systems, offering an efficient and reliable solution.

 

(5) Its deep post insulator ensures outstanding resistance to wear from lateral loads, lowering track maintenance costs.

 

(6) The system allows fine gauge adjustment through its insulators, helping maintain track alignment-especially on tight curves-and extending the service life of assembly components.
