Description

Technical Field

[0001] This invention relates to the field of coil lifting technology, and more particularly to a large coil lifting device. Background Technology

[0002] Large coils also refer to steel coils, which are steel products that have undergone hot rolling or cold rolling. They are long and thin strips in shape. Steel coils are usually made from hot-rolled or cold-rolled steel plates through a continuous rolling process. They can be used to manufacture various steel products, such as automotive parts, building materials, home appliances, and metal containers. The main characteristics of steel coils are dimensional stability, good surface quality, and uniform mechanical properties. Generally speaking, cold-rolled steel coils have better surface quality and higher dimensional accuracy, making them suitable for products with high surface requirements, while hot-rolled steel coils have a wider range of sizes and more applications.

[0003] Large coils are used in many fields. Sometimes, when transporting large coils, it is necessary to lift them. Therefore, a large coil lifting device is needed.

[0004] Existing large coil lifting devices have certain drawbacks in use. Due to the heavy weight of the large coil, they are usually used when the distance between the upper and lower planes is not too large. However, they cannot meet the needs of lifting large coils over long distances or with heavy weights.

[0005] Therefore, a large coil lifting device is proposed. Summary of the Invention
