The crane hook plays a role in connecting goods and bears a great deal of force during use. Coupled with the friction of the steel wire rope, if not properly inspected, it may lead to breakage and accidents. Therefore, the requirements for this type of product are very high during use, and from installation to inspection, it should not be careless The inspection of crane hooks should not only be frequent but also meticulous. Many problems are not easily visible to the naked eye, and they need to be inspected using tools such as magnifying glasses to make it easier to detect cracks. If cracks appear, they must not be used after welding. After welding, the surface structure will be damaged, resulting in a further decrease in strength, so they can only be scrapped

Scrapping standard for crane hooks: Newly put into use hooks should undergo a load test, with 1.25 times the rated load as the test load (which can be conducted simultaneously with the dynamic and static load test of the crane), and the test time should not be less than 10 minutes. After the load is removed, there should be no cracks, fractures, or deformations on the hook. If there are any, they should be scrapped According to international standards, after hanging and removing the test load, the opening of the hook should not exceed 0.25% without any significant defects or deformation. In order to prevent hooks and detect unexpected accidents, the hook should be equipped with safety devices to prevent hooks Hook is a load-bearing object that is prone to cracking after long-term use. Therefore, it should be inspected regularly for flaw detection. Generally, magnetic particle, penetration, and other methods are used for flaw detection inspection. The inspection cycle of the hook can be determined based on its usage environment and frequency, usually once every six months to one year
