Product Introduction
GB crane rails refer to rails produced according to national standards, with special cross-sectional shapes, specially adapted to the crane running track, capable of withstanding the complex stresses generated during the crane operation process, and ensuring the normal operation of the equipment.
As the core materials for crane track laying, U71Mn and QU80 crane rails play an important role in the industrial field, especially in heavy machinery operation scenarios. Among them, U71Mn steel is a manganese-containing carbon steel. The addition of manganese not only significantly improves the strength, hardness and wear resistance of the steel, but also maintains good toughness and achieves a balance between strength and toughness. This unique performance advantage enables U71Mn steel to cope with complex and changing working conditions.
U71Mn QU80 crane rails are widely used in various industrial plants other places. Taking port container cranes as an example, in the face of high-intensity impact and wear caused by frequent loading and unloading operations, U71Mn crane rails can also effectively reduce the frequency of track maintenance and improve port operation efficiency.
