Product Introduction
GB crane rails are produced according to GB standards, have specific mechanical properties and geometric shapes, and are designed specifically for crane running tracks. GB QU120 crane rails can significantly increase the contact area with the wheels and effectively disperse the load due to their large rail head width and thick rail bottom. In large construction sites, large storage and logistics centers and other scenarios, they provide solid and reliable running tracks for cranes, helping to accurately lift and install various materials.
QU120 crane steel has the outstanding characteristics of high hardness. It is not easy to deform even during long-term use. The rail surface can well resist the friction and wear caused by the frequent rolling of crane wheels. During long-term use, the wear degree of the rail surface is relatively small, and it can maintain a good surface finish and geometry, reduce the rail size changes and surface unevenness caused by wear, and thus extend the service life of the rail. For example, in the crane operation of large ports, there are repeated lifting operations every day. With its high hardness and good wear resistance, the QU120 rail can withstand frequent wheel rolling and operate stably for a long time.

Product Maintenance
Proper maintenance and care are essential to maintain the high hardness and performance of QU120 tracks. Regular cleaning, lubrication and inspection of the tracks can reduce wear and corrosion on the track surface and avoid reducing the track hardness due to the embedding of foreign particles or the action of corrosive media.
For example, in some humid industrial environments, if the accumulated water and rust on the track surface are not removed in time, the track surface may rust, which in turn affects its hardness and wear resistance. In addition, reasonable lubrication can reduce the friction coefficient between the wheel and the track, reduce the generation of frictional heat, and avoid the reduction of track hardness due to overheating. At the same time, regularly checking the wear and hardness changes of the track, timely discovering problems and taking corresponding repair or replacement measures can ensure that the track always maintains a good working condition and gives full play to its high hardness advantages.
