Specification and application of eyebolt seven pre

There are many kinds of ring slings used in life, such as ring screws and ring nuts, which are well-known ring slings. Eyebolt, also known as eyebolt, eyebolt, Eyenut, etc. in custom, is very different from the eyebolt in sports. Also known as eyebolt in custom, it belongs to mold fastener. Ring screw products are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railways, construction and so on. If you are interested in eyebolt, you might as well come with me to understand it

introduction to ring screws

ring screws, integrally forged, normalized + oxide skin removed; Forgings are free from defects; After hardness test, the hardness value of ring screw is hrb67~95. The strength of the crown ring screw is grade 12.9

must be installed vertically on the plane of the workpiece, and the joint surface is flat and tight. It must be adjusted to the stretching direction to avoid contact with sharp edged objects

ring screws, the test load is 2.5 times the working load, and 20000 fatigue tests are carried out under 1.5 times the working load. Eyebolt, in accordance with ASME b30.26. It is made of alloy steel with high reference to Germany's rud WBG type, exported to Europe and the United States in large quantities, and passed the g80 standard inspection. The material is higher than the tension of domestic eyebolt, and the tension test report is provided. It must be operated by professional personnel, and please refer to the instructions for use. When connecting with the sling, keep the connecting part of the sling and the ring rotating freely, and professional personnel should conduct regular safety inspection. The maximum working load is 30t, and the British thread can be customized

ring screw usage

ring screw is widely used in port, shipbuilding, railway, construction, plastic machinery, industrial control, pipeline auxiliary equipment, marine rescue, airport construction, aerospace, stadium and other important industries, as well as mechanical equipment of infrastructure construction projects

seven precautions for the use of ring screws

1 Users must be trained before use, in order to use the product correctly and ensure safety

2. Choose the correct type, grade and length of eyebolt for different occasions and application scenarios

3. Before use, check carefully to see if there is damage. If there is, replace it immediately

4. Screw it until it fits closely with the support surface, and it is not allowed to use the tool plate to tighten it

5. The lifting direction of ring screws of different models should be within the range of stress direction. For example, the lifting ring screws have national standards, American standards and other standards to ensure that they are within their stress range

6. The maximum lifting weight is the rated load and cannot be overloaded, otherwise serious consequences will occur

7. If it is found that the wear exceeds 10% of the interface diameter during use, it must be stopped. If it is used forcibly, safety accidents are likely to occur
