2. The new hook should undergo a load test, and the measured hook opening should not exceed 0.25% of the original opening.
3. During use, the hook should be regularly checked for cracks, severe deformation, corrosion, and wear
4. The hook should be tested once a year. During the experiment, a static test should be conducted for 10 minutes under a load of 1.25 times the allowable working load. The test should be checked with a magnifying glass or other methods, and there should be no cracks, cracks, or residual deformation.
5. Three dangerous sections should be cleaned with kerosene and examined for cracks using a magnifying glass. The wear of the lining and pin should be checked for the plate hook.
6. Defects on the hook shall not be repaired by welding.
Safety inspection of stage electric hoist hooks
1. The hook used for manually driven lifting mechanism shall be tested with 1.5 times the rated load as the inspection load.
2. The hook used for the power driven lifting mechanism shall be tested with twice the rated load as the inspection load.
3. After removing the inspection load from the hook, there should be no obvious defects or deformations, and the increase in opening should not exceed 0.25% of the original size.
4. Qualified inspection hooks should be marked in the low stress area of the hook, including the rated lifting capacity, factory logo or name, inspection mark, production number, and other content.
