60Si2Mn Painted Galvanized Elastic Rail Clip Easy Install For Rail Fastening System
Product Description
Rail clip (often just called a clip) is the essential fastener that clamps and holds the rail firmly down to a baseplate, which is secured to a concrete or wooden sleeper (tie).
Think of it as a specialized, heavy-duty spring clamp. Its primary job is not just to prevent vertical movement, but to provide a constant, elastic downward force that resists the rail from lifting, rolling over, or shifting sideways under the immense and dynamic loads of passing trains.
Key Features & Purposes:
Elastic Grip: Unlike a rigid bolt, a clip is designed to flex. This elasticity allows it to absorb vibrations, compensate for thermal expansion/contraction of the steel rail, and maintain constant pressure without loosening.
Ensures Stability: By securing the rail, it maintains the correct track gauge (distance between rails) and alignment, which is critical for safety and smooth operation.
Durability: Made from high-strength spring steel, it is built to withstand billions of load cycles over decades with minimal maintenance.
In short: It is the critical component that creates a secure, resilient, and long-lasting connection between the rail and the rest of the track structure. Common international types include the SKL, Nabla (e-clip), and FastClip (FC) systems.
