QU120 U71mn Crane Heavy Guide Steel Rail

The QU120 crane steel rail is a high-strength rail designed for ultra-heavy-load lifting systems. It is widely used in shipbuilding, port yards, heavy metallurgy, and large-scale equipment manufacturing.

Made from U71Mn high-manganese alloy steel, the track combines high strength with excellent toughness, maintaining a stable geometry under continuous high-pressure loads.

Compared to lightweight rails, the QU120 features larger dimensions and greater bending moment resistance, making it particularly suitable for long-distance operations in monorail and gantry cranes.

QU120 crane rail is a high-strength specialized track solution widely used in industrial scenarios requiring heavy lifting and transportation, such as ports, shipyards, steel plants, and construction sites, and is particularly suitable for very large equipment and high-frequency heavy-duty conditions.

High-strength performance: QU120 rail, made of U71Mn alloy steel (tensile strength ≥900MPa, HB 380-420), resists deformation under heavy loads, ideal for cranes and railways. Maintains stability in high-frequency operations.

Applicable wheel pressure: 100-400 tonnes, suitable for ultra-large gantry cranes, port container cranes and other heavy-duty equipment.

Long service life: The optimized crystal structure provides excellent fatigue resistance, minimizing the risk of cracks and deformation and extending the rail service life by over 30%. Operators can reduce replacement frequency and maintenance costs, enhancing the operational efficiency of overall logistics or railway systems.

Safety-Oriented Design: The hardened rail head (HB 380-420 hardness) and high-precision geometry (straightness ≤1.5mm/m) ensure stable contact between wheels and rails, effectively preventing operational failures caused by wear or misalignment. This provides a safe and smooth running track for lifting equipment and trains.

One-to-one project support: We offer one-on-one project support, including rail selection guidance, drawing confirmation, and accessory matching. Technical team with deep industry expertise ensures smooth implementation for international projects
