The single hook is easy to manufacture and use, but the stress condition is not good. It is mostly used in workplaces with a lifting capacity of less than 80 tons; The lifting capacity is large, and the double hook with symmetrical force is often used. The laminated hook is riveted by several cut steel plates. In case of cracks in individual plates, the whole hook will not be damaged, with good safety, but its self weight is large. It is mostly used on cranes with large lifting capacity or lifting molten steel drums. The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness.
