Installation Guidelines
Preparation
Pre-drill holes (2mm smaller than spikes)
Apply anti-split compound
Clean seating surface
Positioning
Align with sleeper centerline
Verify proper rail cant
Spiking
Drive spikes at 90° ±2° angle
Use calibrated spike maul
Surface Prep
Clean shoulder area
Apply corrosion inhibitor
Bolting
Torque to 300Nm (M24) or 450Nm (M27)
Follow star pattern sequence
Verification
Check plate seating (0.1mm feeler gauge)
Measure rail inclination
