Railroad Clip

What are railroad clips? Railroad clips are rail fastening components used on railway tracks to connect rails and sleepers (or other types of rail foundations), which is an intermediate connecting components. Their function is to fix the rails to the sleepers, maintain track gauge, and prevent longitudinal and lateral movement of the rails relative to the sleepers.

Rail fastener classification: Based on a classification of various rail fasteners used in national railways and local urban rail transit systems over the past decade, they can be broadly categorized into 4 series:

Traditional Fasteners
Underground Line Fasteners
High-speed Railway Lne Fasteners
Crane and Industrial Railroad fasteners

Tips For Choosing The Right Railroad Clip Models

AGICO has provided useful tips for customers who don’t know which model to use, the selection of railroad clips is mainly based on the following factors, you can offer these information to AGICO and we will give you the best choice:

Operating Conditions: including design speed, axle load, and transport capacity of the railway line .
Track Structure Type: ballast or ballastless track, sleeper type (wooden/concrete), etc.
Environmental Requirements: especially in urban areas, where vibration and noise reduction are critical.
Economy and Maintainability: considering the price of the railroad clips and the workload of subsequent maintenance and repair.
