High-bearing capacity GB QU120 impact-resistant rail is a special rail used for crane rails, usually made of U71Mn. This steel contains a high manganese content, which can improve the strength, hardness and wear resistance of the rail. The tensile strength is not less than 900MPa, and the yield strength is high. It can withstand the huge load during the operation of the crane, including the crane's own weight, lifting weight and dynamic load during operation, and is not prone to deformation and fracture. It has good impact toughness and can avoid brittle fracture under special working conditions such as low temperature, ensuring the reliability and stability of the rail under various environmental conditions.

Product Applications
Mainly used in the running tracks of various large cranes, such as bridge cranes and gantry cranes in large factories, and cranes used for loading and unloading goods in ports and docks. Cranes in these places usually need to frequently lift heavy objects, and have extremely high requirements for the bearing capacity, impact resistance and stability of the rails. QU120 impact-resistant rails can well meet these requirements and ensure the safe and stable operation of cranes.
