Rail Clamps, also called railroad clamp, rail clamp, track clamp, mainly used in railway clamping fastening systems, which belong to rigid-type fasteners. Guard Rails, also called check rail, restraining rail, guardrail, it is installed in track curves where the high rail wears rapidly in order to reduce rail wear in sharp curves and to increase the trackâ??s resistance to flange climb derailment. Guard rails are placed parallel to regular running rail along areas of restrictive clearance, such as a bridge, viaduct,� trestle, or tunnel. Guardrails are necessary because they control and guide the wheels on the right path. Guard Rail Clamps for Rail Fastening Systems.
