Product Introduction
GB crane rails are special rail steels, mainly used for running rails of various cranes, port loading and unloading equipment and heavy factory and mine transportation systems. Its cross-section design especially strengthens the rail head width and rail waist thickness to enhance the bearing capacity and impact resistance, meeting the special needs of frequent start and stop and heavy-load operation of cranes.
In terms of production technology, it mainly adopts the traditional converter or electric furnace steelmaking process, combined with hot rolling forming technology, and a series of standard processes such as rolling, slow cooling, and straightening to ensure that the internal metallographic structure of the rail is uniform and the mechanical properties are stable.
QU70 crane rails, usually made of U71Mn, are important in mining railway cranes. U71Mn is a medium manganese low alloy steel with manganese added to carbon steel. This material makes QU70 rails have high strength, with a tensile strength of not less than 880N/mm², and can withstand the heavy loads of mining cranes and transportation equipment. At the same time, it also has good wear resistance, fatigue resistance and toughness, can resist the wear caused by frequent driving of mine cars, withstand the impact loads in mining operations, adapt to harsh working environments, and reduce the frequency of track maintenance and replacement.

Product Packaging & Delivery
The rail surface is painted with high temperature resistant anti-rust oil, which can withstand high temperature. It is wrapped with aluminum foil composite anti-rust paper, and the outer layer is wrapped with reflective plastic film. The strapping adopts 7 12mm wide galvanized steel belts, and a pneumatic baler is used to ensure the uniform strength. The packaged rails are laid flat on the fumigated poplar pallet in groups of 5.
