　　The types of hooks can be divided into single hooks and double hooks according to their shape; they can be divided into forged hooks and stacked hooks according to their manufacturing method.

　　The hook, whose English name is lifting hook, is a common spreader in lifting machinery. The hook is often suspended on the wire rope of the lift with the help of various components such as pulley sets.

　　However, the classification of hooks is extremely wide, including: shackles, rings, rings, pear-shaped rings, long rings, combined rings, S-hooks, nose hooks, American hooks, sheep horn hooks, eye-shaped sliding hooks, ring screws with safety card, chain shackles, etc. It has unique, novel, high-quality, and safe characteristics, and is also suitable for factories, mines, petroleum, chemicals and ship terminals. In order to ensure safety, its quality and safety factor are 3 times the static load, including its lifting weight, also from 5 tons to 150 tons.

　　However, the single hook of the hook is very simple to manufacture and convenient to use, but the stress is not good, and it is mostly used in some workplaces with a lifting weight of less than 80 tons; when the lifting weight is large, double hooks with symmetrical force are often used. The stacked hook is made of several pieces of cut steel plates. Although the entire hook will not be damaged when cracks occur in some sheets and is safer, it has a large weight, so it is mostly used on cranes that lift large lifting weights or lift steel buckets. However, hooks are often impacted during operation, so they must be made of high-quality carbon steel with good toughness.
