Inspection method for eye hooks:
The eye hook should pay attention to the environmental conditions when used in conjunction with the rigging, and the rigging must not be twisted and knotted. During the lifting process, the hooks are strictly prohibited from being impacted and impacted.
At present, the eye hooks are generally forged single hooks, the cast hooks are not allowed on the crane, and the eye hooks are widely made of low carbon steel and carbon alloy steel.
The main method of testing the eye hook:
Visual inspection is generally used in practice, that is, careful observation with a magnifying glass. If necessary, you can use the coloring method or perform flaw detection. The amount of wear on the dangerous section can be measured with a caliper or with a caliper; the degree of opening is checked by comparing the measured dimension of the caliper with the original size or the opening of the standard hook. Here is a simple and applicable method: when the new crane hook is activated, a small hole is punched in each side of the hook opening, and the distance between the two holes is measured and recorded. It is used to compare the size of the hook after the deformation of the hook to determine the change in the degree of opening. The torsional deformation can be visually observed, and can also be measured by the side of the steel ruler. When it is required to be accurate, it can be detected by a ruler on the platform.
