There are many kinds of doors, and rolling shutter door is one of them. Curtain door is characterized by convenient operation, so it is widely used in garages, shopping malls and stores. However, no matter what kind of goods, they will be worn one day, so they need to be repaired. How can they be repaired? Maybe this problem will embarrass some people. Xiaobian will help you solve it. The following is a detailed introduction. I hope it can be helpful to you.
1、 Repair method of broken spring of rolling shutter door
1. The installation method of torsion spring is to grasp the shell of torsion spring by hand, and then grasp it upward facing people (from the front).
2. Hold the screw on the door tightly with your left hand, and then use your right hand wrench (tool torch off). After unloading, slowly release the spring with both hands until there is no resistance, and so on.
3. Remove the winding (beam) wire on both sides of the manual girder, take it down on the ground, then remove the spring wire on the manual curtain door, remove the new spring sleeve, and then fix the screw. Of course, the winding (beam) is also installed according to the old style.
4. Starting to tighten the spring is also a key operation (in fact, it was in the opposite direction at the time of previous disassembly). Tighten to the required resistance and replace the spiral rib.
5. To replace the leaf spring, first grasp the spring shell of the torsion spring and grasp it upward in the direction facing people (from the front). After grasping with the left hand, remove the hook plate with the right hand (if the spring of the manual rolling shutter door is broken, the hook can be removed directly).
6. Then remove the spring. The steel tank must be 80cm longer than the door. Then remove the previous screw, install the manual rolling shutter door spring, tighten the spring to high resistance, and hang the hook.
7. In fact, the basic principle of leaf spring and torsion spring is the same. When changing the spring, it should be noted that ordinary users cannot suddenly pull up the curtain. The quick solution is to find technicians to repair the curtain door first, so as to save unnecessary losses. If you don't understand, don't be smart, don't let your own safety steel ball have great power, even technicians. May cause inevitable contusion.
The above is about the daily common fault repair methods of rolling shutter door compiled by Xiaobian. I hope it can be helpful to you. Interested friends can collect and pay attention to it
