QU100 Rail
The QU100 Crane Rail is a high-strength, heavy-duty steel rail designed specifically for crane systems in demanding industrial environments. With a theoretical weight of 88.96kg/m and dimensions optimized for crane operations, the QU100 rail ensures smooth and safe movement of cranes, even under extreme loads.
QU100 Rail Key features
Rail height: 150mm ; base width: 150mm
Web thickness: 38mm; head width: 100mm.
Material:
U71Mn High-Strength Rail Steel (default): Tensile strength ≥880MPa, hardness ≥260HBW, ideal for heavy freight and high-speed applications.
Superior Load-Bearing Capacity:
Designed for crane systems with axle loads up to 200 tons.
High manganese content (1.10%-1.40%) enhances tensile strength and fatigue resistance .
Wear Resistance:
As-rolled hardness of 260-300 HBW (heat-treated variants reach 320-380 HBW) .
Minimizes rail wear in high-traffic environments, reducing maintenance costs by up to 30% compared to conventional rails.
Precision Manufacturing:
Hot-rolled or heat-treated processes ensure dimensional accuracy (tolerance: ±0.5 mm) .
Surface finish meets Ra ≤ 12.5 μm, minimizing friction and extending wheel life .
Corrosion Resistance:
Optional anti-corrosion coatings (e.g., zinc-aluminum-magnesium) available for marine or humid environments.
