　　Hook is an important bearing component of lifting machinery. Its mechanical properties and safety are directly related to the safety of the operator's life and property. Among them, bearing capacity is a key indicator. In order to ensure the safety and reliability of lifting machinery, most countries have formulated relevant technical standards or regulations to supervise the design, manufacturing and use of hooks.

　　Our current national standards also make corresponding provisions on the mechanical properties and materials of hooks. However, for a long time, the strength problem of lifting hooks has mainly relied on theoretical calculations and finite element numerical verification. There is a lack of a good evaluation method for the actual ultimate bearing capacity of hooks that have been produced, especially hooks with large rated lifting weight. Therefore, it is difficult to determine the actual ultimate bearing capacity and safety factor of such hooks relative to the rated lifting weight.

　　Domestic lifting machinery manufacturers have developed a new type of single hook to replace similar foreign products. Its rated lifting weight is 45t and the length along the force-bearing direction is 1.398m. The ultimate bearing capacity of the new sheet single hook developed by the enterprise was tested and tested, providing a technical basis for determining the material selection and production process of the single hook.
