The roller shutter door is divided into:
1. Manually roll up the curtain according to the opening type. With the help of the balance force of the torsion spring on the central axis of the roller shutter, the roller shutter can be pulled manually.
2. Electric roller shutter. Use a special motor to drive the central axis of the roller shutter to rotate, reach the roller shutter switch, and automatically stop when the rotation reaches the upper and lower limit set by the motor.
Therefore, when opening and closing the door curtain, it is forbidden to walk and run, because when opening and closing the door curtain, the door curtain is connected by connectors, and there are almost no unsafe factors in the motor and transmission shaft.
