Brief introduction of crane lifting hook

1.Application of crane lifting hook

Crane lifting hook is the most common hook device in the crane machinery. Hook hangs on the wire rope of the lifting mechanism with the help of pulleys such parts,hook is the most widely used among the load handling device. It has such characteristics as simple manufacture and strong usability.

 

2.Product category of crane lifting hook

Crane lifting hook has single hook and double hooks according to shape of hook, five strength gradesM,P,S,T,V are classified in accordance with mechanical prperty. Forging hook and strap type hook are manufactured according to the method of manufacturing,

 

3.Crane lifting hook

Manufacturing is simple and it is easy to operate. It is mainly used in the workplace below 80t lifting capacity. Force symmetry double hooks are adopted to larger capacity. It is adopts to high-quality low carbon killed steel or low carbon alloy steel,such as 20 high-quality low carbon steel,16Mn,20MnSi,36MnSi,which is annealed after being forged,

 

4.Productive process of crane lifting hook

riveted through several pieces of cutting forming steel,when individual plate has flaws,the whole hook is not damaged,good safety,heavy dead weight,mainly equipped with big lifting capacity cranes or cranes lifting molten steel ladles.
