　　The connection method of the lifting hook and the lifting mechanism wire rope winding system depends on the number of branches carried by the lifting wire rope. When the load-bearing index of the lifting wire rope is 1, the hook can be directly connected to the end of the wire rope.

　　Sometimes, in order to ensure that the hook has enough weight to tighten the wire rope under no load, so as to prevent the wire rope from being unrotated on the pulley or reel due to slack and to achieve a smooth decline in purchasing control, an additional weight is often installed at the end of the rope. When the hook is hung on a wire rope with branches of more than 2, it is necessary to use a hook hanger as an intermediate connection device between the hook and the wire rope. The hook and the hook hanger are collectively called the hook group.

　　The lifting hook can be divided into two forms: long hook and short hanger and short hook and long hanger. The long hook and short hanger is a long hook that mounts the hook and pulley on a shaft, and the hook is an exclusive long hook. The short hook and long hanger are arranged to separate the hook beam from the pulley shaft up and down, and the hook is an ordinary type hook. Obviously, when the lifting weight is the same, the shape of the long hook and short hanger is smaller than that of the short hook and long hanger, thereby increasing the lifting height of the crane. This is the main advantage of long hooks and short hangers.

　　However, the pulleys in the long hook and short hanger must be arranged symmetrically, so the number of pulleys must be even. In addition, its lateral dimension is large, especially when the lifting weight is large, it needs to be installed with more pulleys, the lateral dimension is even more huge, making the bending moment of the hook beam too large and the weight increases. Therefore, long hooks and short hangers are generally only suitable for bridge cranes with small lifting weights and pulley set ratios of even numbers. Because the short hook and long hanger does not have the above disadvantages, it is widely used.

　　To sum up, the knowledge shared by the lifting hook manufacturer and everyone, I hope it can help you.
