　　The development of trade economy carried out in various places has driven the rapid development of port machinery and equipment. While pursuing work convenience, the safety of hook spreaders is increasingly valued. Therefore, for the container spreaders and hooks that are being used, we should pay attention to daily inspection work. So what damages are prone to port container spreaders during daily lifting? Next, the editor will introduce to you:

　　1. Hook-fatigue crack

　　The defects caused by hooks during manufacturing and use include defects caused by poor raw materials and improper forging processes. The defects caused by reducing forging stress and fatigue cracks caused during use. Fatigue cracks can directly cause the hook to be broken due to their great harm. It can be formed by expansion of defects inside the workpiece, but in most cases, the parts of the workpiece surface stress concentration (such as grooves, etc.).

　　2. Detection method:

　　Determine the inspection method based on the shape, shape, surface conditions of the hook and the defect properties (type, size, position, etc.). Different magnetic powder flaw detection methods can display the number and depth of defects. The fatigue cracks on the hook are related to the stress state, and the angle of the hook is mostly in the bent parts and roots. The magnetic marks are generally thick in the middle and gradually thinning on both sides. Usually, the cracks are relatively deep, and the adsorbed magnetic powder is also very concentrated and clear.

　　The above is an introduction to possible damage and detection methods for port container spreaders and hooks. Lifting safety is of great importance. Therefore, I hope everyone can pay attention to the above introduction and do a good job in related inspections.
