In modern industrial production, cranes are key equipment for material handling, and their operation stability and efficiency are crucial. As the basic support for crane operation, QU crane rails of different specifications play their own unique roles.
Common specifications of QU crane rails are QU70, QU80, QU100 and QU120. Among them, the "QU" of QU70 rails stands for track, and the number "70" means that the approximate mass of each meter of rail is 70 kg. Its base width is usually about 70 mm (2.75 inches) and the side height is about 120 mm (4.7 inches), which is suitable for medium-sized cranes such as common bridge cranes and gantry cranes.
QU80 rails are similar to QU70, but with greater mass. Its base width is usually about 80 mm (3.15 inches) and its side height is about 130 mm (5.1 inches). It is suitable for medium and heavy cranes, providing stable support for bridge cranes and large gantry cranes during operation.
QU100 rails, again "QU" stands for rails, and the number "100" reflects the mass per meter of rails. Its base width is usually about 100 mm (3.94 inches) and its side height is about 150 mm (5.9 inches). It is suitable for large and heavy cranes, such as port cranes, which have extremely high requirements for the load-bearing capacity of rails.
QU120 rails are extra-heavy rails with extremely high mass. Its base width is usually about 120 mm (4.7 inches) and its side height is about 170 mm (6.7 inches). It is mainly used in large port cranes, mining cranes and other crane applications that need to withstand extreme loads.
These QU crane rails are generally made of high-strength steel, and the most common ones are carbon steel and alloy steel. They need to meet specific chemical composition, mechanical properties and heat treatment standards to ensure good durability and strong load capacity in heavy industrial applications.
In actual applications, different industries choose QU crane rails of appropriate specifications according to their own needs. GNEE RAILWAY RAILWAY adopts advanced production technology and strictly produces rails in accordance with GB standards. Ultrasonic flaw detection and fatigue resistance testing are carried out on the rails to ensure that customers can be provided with high-quality crane rails to help the development of enterprises.
