PERFORMANCE
Purui's 40-ton crane double hook is the core load-bearing component of lifting equipment. Made from high-strength alloy steel, it undergoes a specialized heat treatment process, resulting in exceptional toughness, wear resistance, and fatigue resistance. Crane hooks are typically equipped with a safety tongue (or anti-unhooking device) that automatically locks during lifting, effectively preventing the risk of unhooking and providing dual protection for heavy-duty operations. This hook has a rated load of 40 tons.
40-ton crane double hook is designed specifically for heavy industrial applications and is widely used in port loading and unloading, steel metallurgy, large equipment manufacturing, infrastructure projects, and other scenarios. It can safely lift large containers, heavy machinery, steel structure modules, and other materials.
Application
As a core load-bearing component, the 40-ton crane double hook is widely used in heavy industry, primarily in port container loading and unloading, steel coil/billet transfer in the steel and metallurgical industry, large-scale equipment manufacturing and assembly, heavy component lifting in power plant construction, bridge and building steel structure construction, and hull section assembly in shipyards. Its high load capacity and reliability enable the safe and efficient handling of large materials, heavy machinery, and modular structures, making it an indispensable key lifting device in modern heavy industrial production and large-scale engineering construction.
