　　As the main tool for material lifting, the emergence of cranes has played a good role in lifting and handling heavy objects in people's operations. For cranes, hooks are one of the very important components. For example, if a crane wants to carry heavy objects, it must have a hook to cooperate.

　　According to the current development situation in the market, there are many common types of hooks, but they are each suitable for different cranes.

　　If divided according to shape, the hooks of the crane can be divided into single hooks and double grooves. In contrast, single hooks are easy to manufacture and use and are used to lift objects with relatively light weight; while the double grooves weigh more and are generally used to lift objects with larger weights.

　　If it is distinguished from the perspective of manufacturing methods, the crane hook can be divided into forged hooks and sheet hooks. The former is mainly used for lifting cranes with lifting capacity below 30T, while the latter is used for lifting cranes with lifting capacity of 75T-350T. In addition, the crane hook can also be distinguished from the cross-sectional shape of the hook body, including round, square, trapezoidal and T-shaped.

　　Analyzing based on the stress conditions, the T-shaped cross-section design is more reasonable, but the forging process of this type of crane hook is also relatively complicated; in comparison, the trapezoidal cross-section is more reasonable and forging is easy; while the rectangular cross-section is only used for sheet hooks, and the load-bearing capacity of the cross-section is not fully utilized; the circular cross-section is only used for small hooks.
