Product Introduction
GB's QU series of crane rails have become indispensable infrastructure materials in the industrial field with their excellent mechanical properties. After special rolling treatment, its tensile strength reaches 900-1100MPa, and the rail head hardness is maintained at HB300-380. Its impact resistance and wear resistance are far superior to ordinary rails.
QU120 Heavy-Duty Crane Steel Performance Advantages
Wide load range: It can withstand 100-400 tons of heavy loads, far exceeding ordinary rails. It is specially designed for large cranes (such as gantry cranes and port container cranes) to meet the extreme heavy load requirements of lifting ladles in steel plants and lifting heavy equipment in mines.
Optimized structural design: The large-size cross-section design disperses the load, reduces the risk of rail deformation, and ensures the safety of the track under heavy load.
Strong adaptability to working conditions: Under complex working conditions such as frequent starting and stopping, heavy object dragging, etc., the rail surface can still be kept smooth, reducing the friction loss between the wheel and the track, which is especially suitable for scenes with high dust and severe wear such as ports and mines.
Strict size control: During the manufacturing process, there are strict standards for the lateral curvature, vertical curvature, torsion and other indicators of the rail (such as curvature per meter does not exceed 1.5mm), ensuring that the track is extremely smooth after splicing, avoiding shaking or jamming of the crane during operation.
