　　The crane hook group is a combination of the sliding wheels of the hook and pulley group. There are two types of hook groups: long and short.

　　The long hook group uses a short hook with a short hook handle, which is supported on the hook beam, and the pulley is supported on a separate pulley shaft. Its height is larger, reducing the effective lifting height.

　　The short hook group used to use long hooks. The pulleys of this hook group were directly installed on the hook beam, and the height was reduced, but they could only be used for double-rate pulley groups. Because the balance wheel of the single-rate pulley set is below, only the long hook set can be installed.

　　The short hook group produced now is similar to the long hook group in mechanism, but has the characteristics of a short one. Short hook sets can only be used for smaller pulley set magnifications. When the magnification is large, the number of pulley sets increases again, and the hook beam is too long, so the bending moment is too large, which makes the hook weigh too much. Therefore, the short hook set is only suitable for smaller cranes.

　　The hook set is the most common spreader in the processing of lifting machinery parts. The hook group is often suspended on the wire rope of the lifting mechanism by means of pulley group and other components.

　　The hook group is divided into single hook and double hook according to its shape; it is divided into forged hook group and stacked hook group (plate hook) according to its manufacturing method.

　　Single hooks are simple to manufacture and easy to use, but the stress is not good, and most of them are used in workplaces where the lifting weight is less than 80 tons; when the lifting weight is large, double hooks with symmetrical force are often used, which are often used in cranes of 50-100T. The stacked hook group is made of a steel plate cut and formed by several pieces. When some plates have cracks, the entire hook group will not be damaged. It has good safety, but has a large weight. It is mostly used on cranes that lift large lifting weights or lift steel buckets. The hook is often affected during operationThe impact must be made of high-quality carbon steel with good toughness. The stacked hook is also divided into single hooks and double hooks. Single hooks are used on cranes with lifting weights of 37.5-175T, and double hooks are used on cranes with lifting weights of more than 100T.
