Product Introduction
According to GB standards, crane rails are rails that have strict quality control and performance requirements and are specially adapted to crane working conditions. As a representative of this type of heavy-duty rails, GB QU120 crane rails are carefully made of calm steel smelted in an open-hearth furnace. The rails have excellent performance in hardness, toughness, and rigidity. Even in a complex working environment, QU120 crane rails can well assist crane operations.
QU120 crane rails are the largest and heaviest aviation crane rails among GB crane rails. They are often used in large industrial scenes such as steel metallurgy, ports and docks, and mining. The larger size and weight of QU120 crane rails give them higher rigidity and stability, which can meet the load-bearing requirements of large heavy lifting.
High-quality U75V steel is selected, which usually has higher hardness and wear resistance. The centerline hardness of the top surface of the rail head is generally between 300 and 380HBW. This enables the rail surface to resist the long-term rolling and friction of the crane wheels, reduce wear and indentation, extend the service life of the rail, and ensure that it can still maintain good working condition under frequent use of heavy lifting operations.
Product Specifications
Product Packaging & Delivery
Installation requirements: The installation of QU120 crane tracks needs to be carried out in strict accordance with relevant standards and specifications. First, ensure the flatness and horizontality of the track foundation, and the uneven settlement of the foundation should be controlled within the allowable range to avoid deformation and cracking of the track during use. Secondly, the laying of the track should ensure its straightness and verticality, and the track joints should be finely processed to ensure the flatness and connection strength of the joints and reduce the impact and vibration during the operation of the crane.
Maintenance: In order to ensure the normal operation of the QU120 track in heavy lifting operations, regular maintenance is essential. Daily maintenance includes cleaning the surface of the track, removing debris and oil stains in time to prevent corrosion and wear on the track surface. Regularly check the wear of the track, especially the rail head and rail waist. When the wear exceeds the specified limit, it should be repaired or replaced in time. At the same time, check the connecting parts of the track, such as bolts, pressure plates, etc., to ensure that they are reliably fastened to prevent looseness from affecting the stability of the track. In addition, the track foundation needs to be inspected. If there is settlement or damage, it should be dealt with in time.
