Rail Clamp With Nuts

Specification

Role and Function of Rail Clamps

Rail clamps are specialized mechanical devices designed to securely grip the head of a rail. Their primary function is to prevent the longitudinal movement of the rail, a force known as "rail creep."

Their key roles and applications include:

Longitudinal Restraint: They are primarily used to anchor rails and resist powerful longitudinal forces generated by accelerating and braking trains, as well as thermal expansion and contraction in continuous welded rail (CWR).

Application on Bridges and Viaducts: These structures expand and contract differently from the ground. Rail clamps are crucial for managing the differential movement between the bridge and the track, ensuring the rail is securely held but not over-stressed.

Use in Expansion Joints: In areas where rail expansion must be actively managed, rail clamps work alongside special expansion devices to allow movement while keeping the rail perfectly aligned.
