What Types of Rail Clips Are Commonly Used?
As a part of railway fastening system, rail clip is designed for resulting in the role of buckle pressure on the track by bending and twisting. Elastic rail clip is a reliable connection between steel rails. Main rail clip function is as possible as ensure integrity of railway track. In summary, elastic rail clips are used to prevent vertical and horizontal movement of steel rail relative to the railway sleeper. And then, rail clip ensure the normal gauge, so as to ensure the safety of rail vehicles.
Commonly used rail clips include E-type clips, SKL clips, and Fastclip fasteners. Other types include Nabla, KPO, and Deenik clips, each with specific designs for different applications and sleeper types, such as concrete sleepers for high-speed rail.
Types of rail clips
- E-type clips: A common type, often shaped like a stubby paperclip, used in regions like America and Canada.
