Product Introduction
GB crane rails are the basic supporting components that are indispensable for the operation of lifting machinery. They adopt a unique trapezoidal cross-section design. This design breaks the structural form of traditional rails and optimizes the force distribution between the wheel and rail by tilting the rail waist toward the rail head. The arc shape of the rail head has been precisely calculated and has a high degree of fit with the crane wheel, which can reduce friction and wear during operation. Taking the QU series as an example, from the QU70 suitable for small and medium tonnage and commonly used in logistics warehouses, to the QU120 that can carry hundreds of tons of heavy objects and plays a key role in port terminals, they provide safe and reliable operating tracks for various types of cranes with their stable structure and precise dimensions. In large logistics transfer centers, GB crane rails support cranes that shuttle between shelves to ensure fast and accurate storage and retrieval of goods.
QU100 U71Mn crane hoist rail is a special type of rail commonly used for crane track laying. It is made of manganese-containing carbon steel U71Mn. The addition of manganese can improve the strength, hardness and wear resistance of the steel. U71Mn steel has high strength, with a tensile strength generally above 880MPa and a yield strength of not less than 580MPa. The good strength performance enables QU100 crane rail to withstand the huge wheel pressure and impact load generated during the operation of the crane. At the same time, it has good wear resistance, can resist the wear caused by the long-term rolling of the crane wheels, and extend the service life of the rail.

Product Packaging & Delivery
When the crane rails are packaged for transportation, quick-drying anti-rust oil is sprayed on the surface of the rails, and then a layer of anti-rust paper is manually wrapped. The outer layer is wrapped with 0.15mm plastic film, and the seams are fixed with ordinary tape. The strapping system consists of 5 8mm galvanized steel straps, with a spacing of 1.8 meters, and is tightened with manual strapping pliers. The packaged rails are laid flat on wooden pallets in groups of 3-4. Conventional loading is used in the container, and desiccant is added according to actual conditions. This packaging method can maintain a good anti-rust effect during the 20-30 day transportation cycle.
