　　The crane needs to cooperate with the hook or other picking devices to complete cyclic operations including hanging heavy objects, lifting and moving in the space. There are many categories of crane hooks, among which semi-closed hook groups are a relatively common category. There are many such devices on the market. In order to improve the performance of this product, our company has adopted a variety of processing technologies, such as the following:

　　1. Use special steel and bars to process and make hook groups. The steel has specific cleanliness requirements and ensures hardenability. It can improve the ductility of the hook set, that is, the ability of the product to deform when overloaded. A warning will be issued to the user before a fault such as a hook break occurs. The cross-sectional design allows straightening of the product before deformation when overloaded.

　　2. Use heat treatment processes such as quenching and tempering to optimize the performance of steel. It enhances the toughness of the material, helps to reduce the risk of catastrophic failures, and makes the semi-enclosed hook set better durability for lifting operations, and repeatedly uses loads without prone to breakage.

　　To sum up, we are some of the processing processes that our company has in producing semi-enclosed hook groups. Through these processes, we not only improve product performance, but also optimize the production process, which makes customers more satisfied.
