The situation of rolling shutter door moving derailment is not uncommon in reality. I believe that the number of people recruited is not in the minority. Have we ever thought about what causes such problems? In fact, the root cause is nothing more than a few. Let's take a look at it quickly!
1. The curtain plate is biased to one side during the lifting process of the door. If the curtain plate is biased to the other side to reveal the degree of derailment, there is no doubt that the material will be shorter. The treatment method is to reinstall the guide rails on both sides and let them all be adjusted to the middle.
2. Is the reversal center of the door shaft horizontal? We professionally install a laser marking instrument, and the family can use a transparent thin plastic pipe to check.
3. Is the riveting head (that is, the plastic thing at both ends of the curtain) really complete when the door is installed at the beginning (if there is no screw on the top piece on the shaft, then the second piece must be available)? Is there any bad one now?
4. Is the axial positioning of the door shaft firm?
5. Is the top curtain connected with the shaft the same length as most other curtains? The short film simply causes the curtain plate to shift.
