Main Functions
Rail Securing:Rail clamps securely secure rails to sleepers, preventing them from moving or shifting.
Load Transferring:Rail clamps transfer loads from the rails to the sleepers, trackbed, and ultimately to the subgrade.
Rail Spacing Adjustment:Rail clamps adjust the spacing between rails to ensure smooth vehicle travel.
