Advantages of QU120 crane rails from GNEE RAILWAY RAILWAYL
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.
As a leading crane rail supplier,GNEE RAILWAY RAILWAYL offers meticulously engineered gantry crane rail and overhead crane rail solutions. We specialize in providing customizable gauge configurations ranging from 600mm to 1520mm, along with tailored cross – sectional parameters to meet diverse project requirements.
