Check if the threaded part of the hook is complete, without looseness or corrosion.

Functional check:

Ensure that the rotating part of the hook rotates freely without excessive clearance or jamming.

Check the opening of the hook to ensure it does not exceed 10% of the original size.

2、 Regular maintenance

Cleaning and lubrication:

Regularly clean the hook to remove dust, oil stains, and impurities from the surface.

Lubricate the hook with appropriate lubricant to ensure the normal operation of its various components.

Component inspection:

Regularly inspect the main components of the hook, such as lifting lugs, lifting rings, and load-bearing pins, to ensure that they are in good condition and free from wear or damage.

Check the wear of components such as pulleys and bearings, and replace severely worn components in a timely manner.

Overload inspection:

Analyze the usage records of the hook and check if there are any instances of overloading.

There are cracks and gaps on the surface.

The opening degree of the hook is greater than 10% of the original size.

The twisting angle of the hook body exceeds the specified value.

The actual height of the dangerous section after wear is less than 95% of the basic size.

The diameter of the hook handle after corrosion is less than 95% of the basic size.

Dangerous sections such as hook tails and threaded parts, as well as hook bars, have plastic deformation.

Testing and Validation:

After replacing the new hook, a functional test should be conducted to ensure that it can work properly.

Load testing can be conducted to verify the load-bearing capacity and stability of the hook.

4、 Safety precautions
