Sliding door

Five major devices to protect the safety of industrial sliding doors:

1. Wire rope anti-breakage device

At the bottom of the industrial sliding door, there are blade-type anti-fall feet (wire rope breakage protectors) at both ends. When the lifting wire rope breaks, the running speed of the door body becomes faster, and the blade on the device can instantly cut into the guide rail under the action of spring force to prevent the door body from falling.

　2. Airbag protection device

An airbag switch is provided at the bottom of the industrial sliding door, and the airbag is connected to the motor. When the industrial sliding door is closed, if a car or a person passes by, the air in the airbag will be squeezed by contacting the bottom sealing strip. The air pressure device in the airbag will work through the control box system to make the motor move backward (door body). is opened) and will not cause damage to objects or people.

3. Anti-spring breakage device

The ratchet and pawl mechanism on the anti-spring breakage device is locked on the door shaft with a key pin. When the spring breaks, the push button of the device will block the ratchet and pawl mechanism, which can prevent the industrial sliding door door shaft from rotating and prevent the door body from falling within 10cm.

4. Infrared protection device

The industrial sliding door body is equipped with an infrared photoelectric protection device to ensure the safe passage of people and vehicles.

5. Resistance from passing through Device

The anti-overflow device is installed on the top of the track to prevent the door body from rising and rushing out of the track when the motor fails, and plays the role of upward buffering and downward pushing.
