QU70 Rail
Product Overview
The QU70 Crane Rail is a high-strength, heavy-duty steel rail designed specifically for crane systems in demanding industrial environments. Crafted from U71Mn steel (a high-carbon, medium-manganese alloy), this rail offers exceptional load-bearing capacity, wear resistance, and stability. With a weight of 52.8 kg/m and dimensions optimized for crane operations, the Qu70 rail ensures smooth and safe movement of cranes, even under extreme loads.
Key features
Rail height: 120mm ; base width: 120mm
Web thickness: 28mm; head width: 70mm.
Material:
U71Mn High-Strength Rail Steel (default): Tensile strength ≥880MPa, hardness ≥260HBW, ideal for heavy freight and high-speed applications.
Key Specifications:
Profile: Symmetrical wide-flange design (52.8kg/m)
Extreme Load-Bearing Capacity
Supports axle loads up to 30 tons, ideal for container cranes and heavy machinery.
Reinforced head and web design prevents deformation under cyclic stress.
Corrosion & Wear Resistance
Zinc-coated or thermal-sprayed aluminum (TSA) options for harsh environments (coastal/chemical plants).
Surface hardness ≥300 HB reduces wear rate vs. standard rails.
Precision Manufacturing
Strict tolerance control (±0.5mm in height/width).
Pre-drilled holes available for fast bolt-on installation.
Applications
Port & Shipyard Cranes
Seamlessly integrates with RTG cranes, STS cranes, and rail-mounted gantries.
Steel Mills & Foundries
Handles molten metal transfer cars and slag pot carriers (temperature resistance up to 150°C).
Heavy Machinery Workshops
Used in rolling mill equipment and large assembly line transporters.
Warehouse Logistics
Supports automated guided vehicles (AGVs) in mega distribution centers.
