Product Introduction
QU rails produced according to GB specifications improve wheel force distribution through rail bottom slope design, reduce wheel tread eccentric wear, and improve the linearity and stability of crane operation.
U75V and U71Mn are two common materials used to manufacture QU crane rails. U71Mn contains a certain amount of manganese, which can improve the strength and toughness of steel, enabling it to withstand the larger load during crane operation. It has good wear resistance and fatigue resistance, which can ensure that the rails are not prone to wear, fatigue cracks and other problems during long-term use, thereby ensuring the safe operation of the crane.
U75V: In addition to basic elements such as carbon and manganese, it also contains vanadium. Vanadium can refine grains, improve the strength and hardness of steel, and improve the toughness and wear resistance of steel. Compared with U71Mn, U75V may have higher strength and hardness, better wear resistance, and is especially suitable for some occasions with high requirements for rail performance, such as crane rails used in large ports and heavy machinery plants.

Product Packaging & Delivery
GNEE RAILWAY RAILWAY is a foreign trade enterprise specializing in the production and export of GB QU series high-hardness crane rails. It strictly follows the YB/T 5055 national standard, is made of high-quality steel, and uses advanced heat treatment technology to make the rail head hardness reach 260-300HB (can be strengthened to more than 350HB). The product has ultra-high wear resistance and impact resistance, scientific cross-section design, and the load-bearing capacity is more than 30% higher than that of ordinary rails. We have a complete quality management system and have passed ISO9001 certification. Our products are exported to more than 160 countries and regions around the world, providing reliable support for heavy lifting equipment in ports, steel mills, mines and other fields. At the same time, we provide technical consulting, customized production and professional logistics services, and look forward to establishing long-term and win-win cooperation with global customers.
