With the upgrading of major enterprises, the doors of factory buildings are also being updated. More and more companies have replaced the original doors with safer and more reliable sectional doors. There are also many customers who don't know how safe the sectional door is. The following will give you a brief introduction.

Four safety configurations for sectional doors

1. Torsion spring anti-break device. This is the standard configuration of the sectional overhead door, which can prevent the torsion spring from breaking during daily work, causing the door panel to fall down and threatening the safety of passers-by.

2. Wire rope fall arrest device. The wire rope of the lifting door is one of the devices to reduce the pulling force of the motor. This device can hold the door panel on the track when the wire rope breaks to avoid injury to passers-by.

3. Airbag. When passers-by pass through the sectional door, as long as they touch the safety airbag at the bottom of the lift gate, the lift gate will open upwards without causing any harm to passers-by or objects.

4. End cushioning. This device is mainly to prevent derailment when the sectional door is fully opened. Without this device, the sectional door is easy to derail when the limit is abnormal, causing injury to passers-by.

The four major devices of the sectional door are standard configurations. In order to save costs, many manufacturers often omit these configurations, which is one of the reasons why some manufacturers have low prices. When choosing a sectional door, you should not only pay attention to the price, but also pay attention to its configuration. After all, safety is always the first.
