• Infrared protection device: A pair of infrared photoelectric protection devices are installed on both sides of the door body to ensure the safe passage of people and vehicles when people or vehicles pass under the door body. (Do not place objects in the safe photoelectric range for a long time)
• Air bad induction protection device: There is a wire airbag switch at the bottom of the door, and the airbag is connected to the motor. When the door is closed, if a car or person passes by, it will touch the bottom sealing strip to squeeze the air inside. , The air pressure device in the airbag will work through the control box system, so that the motor will rotate in the opposite direction (the door body is opened), and will not cause damage to objects and people.

Cut into the guide rail instantly, prevent the door body from falling, effectively prevent the door body from falling, and ensure the safety of people and vehicles.
