In industrial applications, the safety of sectional doors is critical, especially in environments where frequent operation is required. To protect personnel and equipment from unexpected incidents, sectional doors are often equipped with various advanced safety devices. Here are some common safety features that ensure secure operations.

1. Anti-drop Device

The anti-drop device ensures that the sectional door will not fall suddenly in case of a torsion spring or cable failure. This device is activated immediately upon system failure, preventing accidental drops and safeguarding personnel. It is a fundamental safety feature for industrial sectional doors.

2. Infrared Safety Sensors

Infrared safety sensors are typically installed on both sides at the bottom of sectional doors to detect objects passing through. If a person or vehicle is detected, the door is prevented from closing, avoiding collisions. This feature is common in U.S. garage doors and is widely used in industrial doors.

3. Light Curtains

Light curtains provide a higher level of safety protection than infrared sensors. They create an invisible safety barrier across the entire height of the sectional door. If any object passes through the light curtain, the door will immediately stop moving. Light curtains are ideal for high-security applications.

4. Safety Edge or Air Bag System

The safety edge or air bag system is typically installed at the bottom of the door. When the sectional door comes into contact with an object, the airbag detects the pressure and automatically reverses the door's movement, preventing crushing accidents. This is a crucial safety feature for frequently used industrial sectional doors.

5. Finger Safe Panel

The finger safe panel design prevents the risk of fingers being pinched between the door panels during operation. This feature is especially common in the European market, where finger-safe designs have become a standard safety requirement.

6. Spring Break Safety Device

The spring break safety device prevents the door from falling if the torsion spring breaks, ensuring the safety of operators. This is an essential safety feature for industrial sectional doors.

7. Limit Switches

Limit switches ensure that the sectional door automatically stops at pre-set upper and lower positions, preventing it from exceeding its designated range. This device ensures precise operation and enhances overall safety.

Conclusion

The safety devices of sectional doors not only ensure operational safety but also improve efficiency. Choosing high-quality sectional doors guarantees that your business operates smoothly and safely. NHentrance – Your trusted partner in industrial door safety solutions.
