The W14HH Heavy Haul Rail Fastening System is a heavy-duty, high-integrity rail fastening assembly engineered specifically to withstand the extreme stresses of modern heavy-haul freight and high-speed mixed-traffic railway lines.
Designed for demanding environments where high axle loads, tight curvature, and heavy tonnage create severe track degradation forces, the W14HH system ensures exceptional track stability, optimal gauge retention, and minimized maintenance costs throughout its operational lifecycle.
Main Components of W14HH Heavy Haul Rail Fastening:
- 2 × W14R Rail Clips: High-tensile spring steel clips providing reliable and continuous clamping force to anchor the rail securely.
- 2 × Guide Plates: Heavy-duty guide plates ensuring precise lateral alignment and effective load transfer.
- 2 × Plastic Dowels: Cast-in or drilled-in durable insulators offering high electrical resistance and secure anchorage.
- 2 × Sleeper Screws: High-strength threaded fasteners designed to withstand severe vertical vibrations and pulling-out forces.
