In what situations are lifting hooks prohibited? Let's find out!
lifting hook is one of the important components of lifting machinery. Usually used to carry lifting weights.
In daily work, the first thing that is stressed is the material of the hook. What is particularly important is that alloy steel is generally used to use materials such as high hardness and good support toughness.
In the process of use, the following dangerous situations should be avoided:
1. The hook must have a certificate of conformity from the manufacturer and other technical and technological qualification certificates before it can be used formally.
When using, inspection, repair and replacement should be carried out in accordance with the relevant provisions of the "Safety Regulations for Crane Equipment" (GB6067-85).
2. Manufactured hooks cannot be used in lifting machinery equipment.
3. The hook should be equipped with anti-slip devices to prevent accidental slippage of the lifting weight.
4. The surface of the hook should be smooth and free of cracks, edges, burrs, cracks, etc.
5. When one of the following situations occurs, it should be replaced immediately.
When the cross-sectional wear condition of cracks and dangerous parts reaches 10% of the original specification, the opening degree increases by 15% compared with the original specification, the deformation degree is greater than 10°, the plastic deformation caused by the dangerous section or hook force, and the wear condition of the plate hook sleeve reaches 50% of the original specification, a new sleeve should be replaced, and when the wear condition of the plate hook journal reaches 5% of the original specification, a new shaft journal should be replaced.
6. The disadvantage of lifting hooks is that they cannot be welded and repaired.
The above six points are important things that should be paid attention to during use of the hook. The editor reminds everyone that you should observe carefully when using the hook, confirm that there are no abnormalities before using it, so as to avoid safety accidents.
