As the core structure of the crane, the Weihua crane hook is forged from high-strength alloy steel to increase the tensile strength of the hook. It has the characteristics of high strength, modular design and maintenance.
The lifting crane hook is the core load-bearing component of the crane system and is directly related to the safety and efficiency of hoisting operations. This series of lifting crane hooks adopt high-strength materials and intelligent design, and are suitable for heavy equipment hoisting, material handling and precision installation operations in construction, луке, енергија, manufacturing and other fields. The products have passed strict quality certification and take high safety factor, long life cycle and intelligent protection functions as core competitiveness to help customers achieve safe and efficient lifting goals.
