1. U-shaped bolts need to go through multiple processes before they are manufactured, and they have to go through multiple quality inspections before they pass the safety quality inspection. Only U-bolts that have passed the safety quality inspection can be adjusted and installed on various equipment.
2. Regarding the correct operation method of U-shaped bolts, this precaution is the first thing that U-shaped bolt users should pay attention to, because this is the relevant aspect that must be paid attention to when U-shaped bolts are used safely. A good application process will definitely affect the safe use of U-shaped bolts at this time. Therefore, whether the U-shaped bolts are used in accordance with the correct operation method is very important.
3. A wrench is required when tightening the U-shaped bolts. This wrench is used to tighten the wrench. The frequency of tightening the wrench is calibrated once before and after each shift. The fault rule of the calibration is that the calibration cannot be done before working. It is greater than plus or minus three percent of the pre-planning rule value, and the calibration after get off work can not be greater than plus or minus five percent of the pre-planning rule value.
4. The operator should be relatively fixed in the calibration work, and should understand the operating procedures of the U-bolt electric wrench and the calibration equipment and the operating procedures in accordance with the rules and standards. Both the electric wrench and the fixed-torque wrench for tightening U-bolts are calibrated with a torsion meter.
