　　The commonly used hooks currently include single hooks and double hooks. The single hook forging is simple to manufacture and is widely used in small and medium-sized cranes (less than 80 tons). Double hooks are more complicated than single hooks, but they are symmetrical in stress, and the hook body material can be fully utilized, and are mainly used in large cranes (lift weight of more than 80 tons). It is advisable to use touch forging in batches. The stacked hook (plate hook) is made of riveted with multiple cut steel plates and equipped with pads on the hook mouth. This can reduce the wear of the wire rope and allow the load to be evenly transmitted to each steel plate. The stacked hook is easy to manufacture. Since the plate hook will not break at the same time, the working reliability is higher than that of the overall forged hook. The disadvantage is: it can only be made into a rectangular cross-section, the hook body material cannot be fully utilized, the weight is large, and the height is also large. Spread hooks are mainly used on large lifting or metallurgical cranes (such as casting cranes). In the long hook type hook group, the hook beam and the pulley shaft are integrated, with a simple structure, few parts, and small overall size. This is beneficial for making full use of the lifting height, and is more commonly used when the number of wire rope branches is even (usually 4). The short hook hook group has many parts, large height size, but small lateral size, which is beneficial to reducing the deflection angle of the wire rope and is not limited by the number of branches, so it is widely used.

　　The hook group is generally composed of the following types of accessories: hook, hook nut, thrust bearing, hook beam, pulley, pulley shaft and pulley plate.
