GB QU120 Steel Rail For Crane

GB QU120 crane rails are designed specifically for ultra-heavy lifting equipment and are widely used in port gantry cranes, industrial gantry cranes, shipyards, and large factory building crane systems.QU120 rails utilize uniform temperature control and grain refinement during the hot rolling process, ensuring high toughness and fatigue resistance under continuous impact loads. A thickened rail head increases wheel contact area, while the rail base is optimized and widened to reduce stress concentration in the foundation.

QU120 Steel Rail is manufactured from U71Mn or U75V etc through precision rolling and temperature-controlled cooling processes, ensuring stable geometry and excellent wear resistance even under long-term, high-load operation. The QU120 rails offer both strength and guidance, ensuring safe and reliable operation of heavy lifting machinery.

As a professional supplier of QU model crane rails, GNEE RAIL not only provides high-quality QU120 rails but also a full range of compatible installation accessories, ensuring safe and efficient operation of the entire rail system. All accessories undergo strict quality control to perfectly match QU crane rails, enabling "one-stop procurement + worry-free installation."

Fish Plates: Made of Q235B steel with hot-dip galvanizing, they connect QU-series rails with ±0.3mm precision for gap-free bolted joints and stable load transfer.

Rail Clamps: Designed for QU-model rail base, GNEE RAIL supply WJK-welded rail clips, forged from 45# steel with dual anti-corrosive coating. Available in welded/bolted types, their elastic pads reduce vibrations between rails and foundations.

High-Strength Bolts: 8.8/10.9-grade sets meet ISO/GB standards, with Dacromet coating for 500+ hours of salt spray resistance-3x more durable than ordinary bolts.

Rubber Pads: Laid under QU-series rails, these natural/nitrile rubber pads (60-70HA hardness) come in 5/8/10mm thicknesses to buffer pressure and reduce noise.

Rail Pressure Plates: Crafted from QT400-18 ductile iron (galvanized, 400MPa+ strength), their curved design fits QU model rail bases perfectly, minimizing stress for heavy-duty applications.
