GB crane rails are rail products specially developed and produced to meet the special operating needs of cranes. Compared with ordinary rails, it has strict control over chemical composition and rolling process. In terms of chemical composition, the content of impurities such as phosphorus and sulfur is strictly limited to ensure the purity of steel; during the rolling process, the temperature and pressure are precisely controlled to make its hardness reach HB300-380 and the tensile strength reach 900-1100MPa. Such performance indicators enable it to easily withstand the strong impact generated when the crane is started and braked. In addition, the widened design of the rail bottom significantly enhances the connection stability with the foundation. In metallurgical enterprises, even in the face of frequent start-stop and large load changes in the operating environment, it can ensure the continuous and efficient operation of the crane and avoid safety hazards and production stagnation caused by unstable tracks.
Heat treatment is a key step in improving rail performance. Common heat treatment methods include quenching and tempering. Through quenching, the rail surface can obtain high hardness and high strength, improve wear resistance and fatigue resistance; tempering can eliminate quenching stress, increase toughness, and make the rail have both strength and toughness. After heat treatment, the comprehensive mechanical properties of QU100 rails are significantly improved, which can better adapt to the working conditions of frequent lifting and braking of cranes, and extend the service life of the rails.
Gantry cranes have a high lifting height and a large span, and can perform lifting operations in a large space. It can be used in open-air or indoor cargo yards, docks, warehouses and other places, and is suitable for lifting large goods and bulky items.
