For the garage door, presumably we are very familiar with, very common in life. So what should we pay attention to when the garage door is opened and closed?
1. When the garage door is opened and closed up and down, it is necessary to check whether there are objects under the garage door, especially the fireproof garage door, which is often damaged due to improper operation.
2. When the electric garage door is opened and closed up and down, someone needs to be on site. If the curtain is inclined or the track is jammed, the opening and closing of the curtain should be stopped in time to avoid damage to the motor and the curtain.
3. The continuous rolling time of the garage door motor shall not exceed 5-10 minutes. Because the continuous running time of the motor exceeds the specified time, the motor is easy to generate heat. If the temperature of the motor exceeds 120 ℃, the internal thermal protector will cut off power automatically, and the protection device can reset automatically when the temperature drops to 70 ℃.
When the garage door is opened and closed up and down, check whether there are piles, especially the fire garage door is linked with the fire control system, which often leads to damage or tilt of the fire garage door due to improper operation. And ordinary electric garage door should also pay special attention to, the curtain should be opened and closed at the same time, people should be at the scene, in case of the curtain tilt or track jam, should stop the curtain opening and closing in time, so as not to cause more damage to the motor and curtain.
