Remark

1. Overweight operations are strictly prohibited

2. The chain is not allowed to be knotted or twisted during use

3. The length of the chain rigging can be adjusted with a special adjuster

4. Do not load with the tip of the hook

5. The normal working temperature of chain rigging is -40 ℃ to 200 ℃

6. Starting from + 200 ℃, the lifting capacity is reduced to 90%

7. 300% began to improve capacity to 75%

8. Not recommended after 400 ℃
