Brief introduction of eyebolt
Eyebolt, integral forging, normalizing+descaling treatment; Forgings are free from defects; After hardness test, the hardness value of the eyebolt is HRB67~95. The strength grade of Li Guan eyebolt is 12.9.
It must be installed vertically on the workpiece plane, and the joint surface is smooth and tight. It must be adjusted to the stretching direction to avoid contact with sharp objects.
Lifting eye screw, the test load is 2.5 times of the working load, and 20000 fatigue tests are carried out under the working load of 1.5 times. The eyebolt meets the requirements of ASMEB30.26 standard. High-reference German RUDWBG alloy steel production has been exported to Europe and America in large quantities, and passed the G80 standard inspection. The tensile force of the material is higher than that of the domestic eyebolt, and the tensile test report is provided. It must be operated by professionals. Please refer to the operating instructions. When connecting with the sling, the connecting part between the sling and the lifting ring should keep free rotation, and professionals should conduct regular safety inspections. The maximum working load is 30T, and the English thread can be customized.

Use of eyebolt
The eyebolt is widely used in port, shipbuilding, railway, construction, plastic machinery, industrial control, pipeline assistance, maritime rescue, airport construction, aerospace, stadiums and other important industries and infrastructure projects.
Seven points for attention in the specification for the use of eyebolts
1. Users must be trained before using the product, so as to use the product correctly and ensure safety;
2. According to different occasions and application scenarios, select the appropriate eyebolt type, grade and length;
3. Carefully check whether there is any damage before use, and replace it immediately if there is any;
4. Tighten it on the supporting surface, and it is not allowed to tighten it with the tool plate;
5. For different types of eyebolts, the lifting direction should be within the stress direction. For example, the eyebolt has national standard and American standard to ensure that it is within its stress range;
6. The maximum lifting capacity is rated load, and it cannot be overloaded, otherwise the consequences will be serious;
7. If it is found that the wear exceeds 10% of the interface diameter during use, it must be stopped. If it is forcibly used, it is easy to cause safety accidents.
