The 7-shaped coil lifting hook is a special special-shaped lifting equipment optimized and designed based on coil lifting working conditions. Named for its unique 7-shaped structure, it is specially adapted to the lifting, transportation and stacking of various vertical metal coils, widely used in metallurgy, steel processing, warehousing and logistics industries. Integrally forged with high strength without welding splicing gaps, it has high overall strength, good toughness and stable load-bearing without easy deformation, ensuring the safety of lifting operations structurally. The 7-shaped bent structure perfectly fits the stress points on the inner wall of vertical coils, with concentrated and uniform stress during lifting, which can effectively avoid local compression deformation and edge damage of coils, realize lossless lifting, and maximize the appearance quality and service performance of metal coils. With rich specifications, it can adapt to vertical coils such as steel coils, aluminum coils and copper coils with different inner diameters and weights, with strong adaptability to meet the daily lifting needs of small and medium-sized coil workshops. It is light in weight and compact in structure, requiring no complex auxiliary tools, with simple and convenient installation and operation. A single person can complete lifting work with lifting equipment, greatly improving operation efficiency. With quenching reinforcement and anti-rust and anti-corrosion treatment on the surface, it is wear-resistant and impact-resistant, adapting to high-frequency workshop operations and humid and dusty working conditions. Meanwhile, it is equipped with an anti-slip limit structure to effectively lock the coil position and eliminate hidden dangers of lifting sliding with a high safety factor. With the advantages of exquisite structure, lossless lifting, high efficiency and convenience, it has become the mainstream special equipment for vertical coil lifting.
