The efficient operation of cranes is inseparable from the silent support of GB crane rails. GB crane rails, as defined by GB standards, are a type of special cross-section rails that provide precise guidance and reliable load-bearing for cranes, ensuring safe and orderly lifting operations. GB QU120 crane rails have high strength and good wear resistance. The chemical composition and rolling process are strictly controlled during the manufacturing process, making the overall quality of the rails superior. Under the operating conditions of frequent start-stop and heavy-load lifting, they can still maintain a long service life.
QU120 rails are usually made of U75V steel, which can obtain higher hardness after heat treatment. Among them, the addition of vanadium increases the strength and hardness of the steel, and also improves the toughness and wear resistance of the steel.
Compared with ordinary crane rail models such as QU80 and QU100, QU120 rails have higher hardness. This is due to the optimization of its composition design and production process, which makes QU120 rails have obvious advantages in hardness. For example, the hardness of QU80 track may be around HB280 - 320, while the hardness of QU120 track can reach HB320 - 360 or even higher. This difference in hardness enables QU120 track to adapt to more severe working conditions and higher load requirements.
