- Eye screws are mainly used for linking in our daily lives. Their products are mainly used in important industries such as ports, electricity, shipbuilding, petrochemicals, mining, railways, automobile manufacturing, plastic machinery, industrial control, highways, large-scale transportation, pipeline auxiliary equipment, slope tunnels, wellbore treatment and protection, maritime rescue, marine engineering, airport construction, aerospace, venues, and mechanical equipment for infrastructure construction projects.
Some precautions to be taken for the use of lifting ring screws:
1. The user of the hanging ring screw must undergo training before using the product, mainly for the purpose of correctly using the product and ensuring safety;
2. In different occasions and application scenarios, it is necessary to choose the correct model, grade, and length of lifting ring screws, and select suitable products reasonably;
3. Each lifting ring screw must be carefully inspected before use to check for any damage or deformation. If there is any damage or deformation, it should be replaced immediately;
4. The lifting ring screw must be tightened to a tight fit with the support surface, and it is not allowed to use a tool plate to tighten it. It is also necessary to ensure that the thread and thread mouth are tightly matched;
5. The lifting direction of different types of lifting ring screws should be designed within their range of force, and specific standards can be referred to. For example, lifting ring screws have different standards such as national and American standards, as well as different material grades, so it is necessary to ensure that they are within their range of force;
6. The maximum lifting weight of the hanging ring screw is the rated load, and it cannot be used beyond the load, otherwise it will cause other serious consequences;
7. If the wear of the lifting ring screw exceeds 10% of the interface diameter during use, it must be stopped. If it continues to be forcibly used, various safety accidents are likely to occur, so special attention must be paid.
