　　lifting hook As a key component of lifting machinery, its safety and reliability are directly related to the safety and efficiency of the operation. For users who are not familiar with how to check lift hooks, it is crucial to understand the basic inspection steps and precautions. The following are some guides for inspection of lifting hooks provided by manufacturers:

　　1. Appearance inspection

　　Cracks and deformations: First, you should carefully observe whether there are signs of cracks, deformation or fracture on the surface of the hook. Cracked are one of the important criteria for the scrapping of hooks, and any subtle cracks can cause the hook to break suddenly while carrying.

　　Wear and corrosion: Check the surface of the hook for obvious wear, scratches or corrosion. A severely worn hook may not be able to withstand the rated load, while corrosion may weaken the material strength of the hook.

　　Opening degree and twisting degree: Use tools such as vernier calipers to measure the opening degree and twist degree of the hook to ensure that its change is within the allowable range. Excessive increase in opening or excessive distortion and deformation may cause the hook to fail.

　　2. Check the connection part

　　Fastility: Check whether the connection between the hook and the wire rope or other connecting parts is secure and has no looseness.

　　Wear situation: For the threaded parts and connection holes of the hook, the wear situation should be checked to ensure that the wear amount is within the allowable range.

　　3. Workload mark inspection

　　Clarity: Check whether the working load marked on the hook is clearly visible. If the load mark is blurred or worn, the hook should be repaired or replaced in time to ensure that the operator can accurately understand the load-bearing capacity of the hook.

　　4. Use record check

　　Record integrity: Check the use record of the hook, including the date of use, frequency of use, working environment, etc. This information helps to understand the use and working conditions of the hook, and provides a basis for subsequent maintenance and replacement.

　　5. Testing and Maintenance

　　Routine inspection: In addition to daily inspections, the hook should also be tested regularly, including using special instruments to measure the strength and tensile ability of the hook.

　　Maintenance and maintenance: Regularly clean, lubricate and anti-corrosion maintenance of the hook to extend its service life and maintain a good working condition.

　　In short, the inspection of lifting hooks is a meticulous and important task. By following the above inspection steps and precautions, potential safety hazards can be discovered and dealt with in a timely manner to ensure the safe progress of lifting operations. At the same time, it is recommended that users strictly abide by relevant operating procedures and safety standards during use to further ensure operational safety.
