QU70 crane rails are mainly used for large cranes. The theoretical weight of QU70 rails is 52.77kg per meter, with high strength and rigidity. It can withstand the huge wheel pressure and impact force generated by large cranes when lifting heavy objects, ensuring the smooth operation of the crane and preventing the deformation or damage of the rails. And the structural design of QU70 rails gives it good stability. It has a low height, large head width and waist thickness, and this cross-sectional shape helps to improve the anti-overturning and anti-twisting capabilities of the rails. During the operation of large cranes, due to their large weight and large inertia, they have high requirements for the stability of the rails. QU70 rails can provide stable support to ensure that the crane will not shake or deviate during the walking process, thereby improving the safety and accuracy of the operation.
Port
Specialized terminals: In addition to common container terminals, large grab cranes are also used to load and unload bulk cargo in some specialized bulk cargo terminals, such as coal terminals and ore terminals. QU70 rails can withstand the frequent impacts and huge wheel pressure generated by grab cranes during operation, ensuring that the cranes run smoothly on the rails and realizing efficient bulk cargo loading and unloading operations.
Port logistics park: In the logistics park of the port, various types of cranes are set up to achieve rapid transfer and storage of goods, such as rail-mounted gantry cranes (RMGs) and tire-mounted gantry cranes (RTGs). These cranes usually need to frequently move and lift goods in a larger operating area. QU70 rails provide them with reliable operating tracks, which helps to improve the cargo turnover efficiency of the logistics park.

Mines
Open-pit mines: At the mining sites of open-pit coal mines, iron mines and other mines, large mining cranes are needed to install and repair equipment and temporarily lift ore. QU70 rails are laid on the special tracks of the mines, which can adapt to the harsh natural environment and complex terrain conditions of open-pit mines, ensure that the cranes can operate stably under different working conditions, and provide strong support for the mining operations of the mines.
Underground mines: In underground mines, although the space is relatively narrow, there are still some small cranes used for lifting underground equipment and transporting materials. QU70 rails can be laid according to the layout of the tunnels of underground mines. Its high strength and wear resistance can meet the operating requirements of underground cranes in special environments such as wet and dusty environments, ensuring the safety and efficiency of mine production.
Metallurgical plant
Hot rolling workshop: In the hot rolling production line, a crane is needed to lift the heated billet to the rolling mill for rolling, and to lift the rolled steel to the cooling area and finished product area. The QU70 rail can withstand the weight of the hot billet and steel, as well as the impact force generated by the crane during frequent lifting, to ensure the smooth progress of the hot rolling production process.
Cold rolling workshop: The crane in the cold rolling workshop is mainly used to lift cold-rolled strip steel coils, rollers and other equipment and materials. The QU70 rail provides a high-precision running track for the crane, which helps to ensure the positioning accuracy during the cold rolling production process and improve product quality. At the same time, its good wear resistance can adapt to the relatively clean but frequently running working conditions of the cold rolling workshop.
Machinery manufacturing plant
Heavy machinery manufacturing workshop: In workshops producing large machinery and equipment, such as large ship engines and heavy machine tools, cranes need to lift parts weighing tens or even hundreds of tons for assembly and processing. QU70 rails can withstand such huge loads, ensuring that the crane remains stable during the lifting process, providing reliable logistics support for the manufacture of heavy machinery.
Automobile manufacturing workshop: In the stamping workshop and assembly workshop of automobile manufacturing, cranes are used to lift large stamping dies and automobile parts. The high precision and stability of QU70 rails can ensure the accurate positioning of the crane during the lifting process, improve production efficiency and product quality. In addition, its good wear resistance can also adapt to the more frequent crane operation needs of automobile manufacturing workshops.
For light and small cranes, light rails (P-type rails) or hot-rolled railway rails are usually selected. These rails have the advantages of light weight, low price, and easy installation. They can meet the use requirements of light and small cranes and can reduce the overall cost of the equipment.
