What conditions must be met for the use of hooks?
The hook is one of the key parts of the crane. The crane needs to carry a large weight when picking up objects and must meet relevant requirements. During use, the hook is prone to breakage, causing casualties and property losses, and causing major accidents. Therefore, during crane maintenance, do not neglect the inspection of the hook.
The crane hook must meet the following conditions:
1. The hook must be produced by a regular manufacturer, meet the technical conditions and safety regulations of the hook, and have a quality certificate.
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 checked frequently for cracks or serious deformation, corrosion and wear.
4. The hook should be equipped with a locking device to prevent the hanging object from accidentally decoupling.
5. If the hook is defective, it must be replaced in time.
The main method for inspecting the hook is visual inspection, that is, careful observation with a magnifying glass. If necessary, coloring or flaw detection can be used. The wear amount of the dangerous section can be measured with a caliper or a caliper; the opening degree is tested by comparing the size measured by the caliper with the original size or the opening degree of the standard hook.
