GB Standard QU70 Crane Rail

QU70 crane rail is a steel track developed for small and medium-sized industrial lifting systems, providing precise guidance for factory gantry cranes, warehouse equipment, and workshop conveyor lines. This track is renowned for its compact structure, smooth operation, and excellent seismic resistance. Its mechanically optimized cross-section distributes concentrated loads across a limited rail base area, reducing foundation stresses. The toughness and wear resistance of U71Mn steel ensures that the track surface remains intact even under repeated impact.

Made of U71Mn high-manganese steel, the rails undergo multiple cooling stages and straightening after hot rolling to enhance grain uniformity. Their microstructure features a fine pearlite structure, significantly enhancing wear resistance. Each rail undergoes hardness testing, metallographic analysis, and waveguide testing before shipment to ensure dimensional deviation, straightness, and surface integrity meet the national standard GB/T 2585.

GNEE RAIL offers precise cutting to length, drilling, and corrosion protection services tailored to meet diverse installation requirements.

The QU70 track is primarily used for medium-sized gantry cranes, indoor crane systems, logistics transfer equipment, and guide rail systems within manufacturing workshops. Its lightweight structure withstands sustained dynamic loads while facilitating installation and maintenance.

GNEE RAIL offers a variety of track fixing solutions tailored to customer needs, ensuring stable performance despite high-frequency operation and temperature fluctuations.
