In the past, roller shutter doors used to be troublesome for everyone to use, but now with the emergence of electric roller shutter doors, this problem has been solved. Then where is the manual hole of electric roller shutter doors? Next, Jinan electric roller shutter door installation and maintenance personnel will explain it for you.
There is a manual chain on the motor of the electric roller shutter door, which can be pulled upward. The electric roller shutter door with the spring balance system has a manual electric switch, and some electric doors have a hand handle. Different types of electric roller shutter doors have different manual modes.
1. You can directly pull the hand rocker, but it may take some effort to manually pull it through the manhole, and slowly the roller shutter door will be opened.
2. The chain is directly pulled by the external motor, the tubular clutch motor is manually clutch, the tubular hand motor pulls the hand lever, and then manually pulls up the roller shutter door body to open the roller shutter door. If you are in a hurry, you can use pliers to remove all the rivets on the iron sheets on both sides of the lock hole, and then push the lock inward. It is estimated that it will be almost enough.
In addition, some precautions should also be taken into account:
1. When the roller shutter door is opened and closed up and down, check whether there is anything piled up. In particular, the fire shutter door is linked with the fire fighting system, which often leads to damage or inclination of the fire shutter door due to improper operation. Ordinary electric roller shutter doors should also pay special attention to the fact that people should be present at the same time when opening and closing the door curtain. In case of door curtain tilting or track clamping, the opening and closing of the door curtain should be stopped in time, so as not to cause greater damage to the motor and the door curtain.
2. When opening and closing the door curtain, pedestrians and running are strictly prohibited, because the door curtain is connected through a connecting piece when opening and closing the door curtain, and there are few unsafe factors in the motor and transmission shaft. Therefore, when starting the door curtain, try not to let anyone run.
3. Businessmen should also pay more attention to the selection of light, strong and durable materials, which can play a higher safety role even in special cases.
4. The selection of the roller shutter motor is also a relatively important link. Remember not to feel that the lifting force is sufficient, because the bearing capacity of the roller shutter motor will slowly reduce the actual lifting effect over time, so the selection of materials should exceed the actual lifting force of the door curtain as far as possible.
The overall use feeling of the electric roller shutter door is better than that of the ordinary roller shutter door, mainly because it is equipped with a motor, so we don't need to work hard to operate it. Of course, sometimes we need to use hand remote holes when problems occur. Come to our website for more information http://www.jnyuqilin.com Let's consult.
