　　Hook is one of the commonly used spreaders in lifting machinery. In the lifting mechanism, components such as pulley sets are usually hung on the wire rope using a hook. According to its shape, it can be divided into single hook type and double hook type; according to the manufacturing method, it can be divided into forged hook type and laminated hook type.

　　Semi-closed hook group is also a commonly used type of crane. Let’s learn how it is maintained!

　　Semi-enclosed hook group is made of riveted with multiple steel plates. The hook group is one of the important stress-bearing components of the van. It accepts both the components of the hanging object and the impact load generated by the hanging object when the mechanism starts and brakes. Therefore, the hook group is required to not only have high mechanical strength, but also have good toughness. The forged hook data mostly uses 20,20 SiMn steel, and the plate hook data mostly uses Q235,16Mn steel. Therefore, we need to choose different hooks according to the type of hook. As long as we choose products according to our needs, we can ensure the safety of the operation of large cranes.

　　1. The positioning bolts, opening pins, and nuts above the thrust bearing of the hook are not short of tightening and are connected firmly;

　　2. When using the lifting ring, it must be subjected to vertical force, and it is strictly forbidden to apply to horizontal force;

　　3. When the ring is rotated, the thread of the ring must be tightened to prevent loosening and causing the object to fall off;

　　4. When using two rings together, the angle between the surfaces of the two rings shall not be greater than 90 degrees;

　　5. The hooks and rings used in lifting operations must be surface lubricated without any defects, such as breaks, peeling, marks, sharp angles, seams and cracks;

　　6. It is prohibited to use hooks and rings overload;

　　7. The use of rotatable hooks is prohibited; the use of hooks and rings after rewelding is prohibited;

　　8. The use of hooks with angles above 10 degrees

　　9. When using hooks to connect heavy objects, the position and force of the hooks must meet the requirements.

　　The above are some of the contents maintained by the semi-enclosed hook group after use. You can find out if you have any questions or needs, you can contact us directly, or leave your needs and contact information directly on the website, and we will contact you in time!
