Aluminum alloy rigid fast doors are widely used in scenes such as the food industry, and their safety is of vital importance.
The following is an introduction to the common safety protection devices and functions of aluminum alloy rigid fast doors:
1. Infrared safety protection grating
Aluminum alloy rigid fast doors are usually equipped with infrared safety protection gratings, and opposing gratings are set on both sides of the door frame. When there is an obstacle under the fast door, the door body remains open; if an object passes through when the door body is descending, the door body will automatically open to the open position, and then delay the descent when there is no obstacle below. This device can effectively prevent people or objects from being pinched or damaged during the descent of the door body.
2. Bottom safety protection edge
Some aluminum alloy rigid fast doors are equipped with safety protection edges at the bottom. When the door body is descending, if the object is in the blind spot of infrared safety protection, when the door body presses the obstacle below, it will quickly rebound to the most open position, thereby effectively protecting the objects or pedestrians below from harm.
3. Anti-pinch photoelectric system
Fast doors are generally equipped with anti-pinch photoelectric systems, which is an advanced anti-pinch protection technology. Objects near the door body are detected by photoelectric sensors. Once an object is detected entering the danger zone, the door body will immediately stop descending and rebound to avoid pinching people or damaging items.
4. Emergency opening device
In the event of a power outage or emergency, the emergency opening device equipped with the aluminum alloy hard fast door can manually open the brake and lift the door body with the help of the balance system, thereby solving the problem that the door body cannot be opened due to power outage or failure. This device ensures that people and objects can pass smoothly in an emergency.
5. Safety reminder device
Some aluminum alloy hard fast doors are equipped with safety reminder devices, such as voice prompts or warning lights. When the door body is about to close, a voice prompt or flashing warning light will be issued to remind people and vehicles to pay attention to safety and avoid accidents caused by negligence.
6. Anti-collision reset device
In some high-demand scenarios, such as aluminum alloy hard fast doors used in clean rooms, anti-collision reset devices are equipped. If the door curtain is knocked out of the guide rail, it will automatically reset in the next operation to ensure the normal operation of the door body while reducing the risk of damage caused by collision.
7. Multiple safety locking mechanisms
In order to further improve safety, some aluminum alloy rigid fast doors are equipped with multiple safety locking mechanisms. For example, when the door body is closed, a mechanical lock or an electronic lock is used to ensure that the door body is firmly closed to prevent unauthorized personnel from forcibly entering.
8. Wind pressure resistance design
In an environment with high wind pressure, the wind pressure resistance design of aluminum alloy rigid fast doors is crucial. By adopting high-strength aluminum alloy materials and reasonable structural design, the door body can withstand large wind pressure and ensure stability and safety under severe weather conditions.
9. Airbags
Some high-end aluminum alloy rigid fast doors are equipped with airbags at the bottom of the door body. When the door body descends, if it contacts an obstacle, the airbag will act as a buffer, reduce the impact force, and protect the safety of people and objects.
10. Safety certification and standards
Aluminum alloy rigid fast doors should comply with relevant safety standards and certifications, such as ISO9001, CE, etc. These certifications indicate that the manufacturer follows certain production standards and processes to ensure the quality and safety of the product. In addition, the design and installation of rapid doors should comply with national standards and industry standards, such as “Rapid Doors” GB/T 19301-2003, “Industrial Doors” GB/T 19063-2003, etc.
Summary
Aluminum alloy rigid rapid doors are equipped with a variety of safety protection devices, such as infrared safety protection gratings, bottom safety protection edges, anti-pinch photoelectric systems, emergency opening devices, safety reminder devices, anti-collision reset devices, multiple safety locking mechanisms, wind pressure resistance design, airbags, etc., which significantly improves the safety during use. At the same time, products that meet relevant safety standards and certifications can provide users with more reliable protection. When choosing aluminum alloy rigid rapid doors, you should ensure that they have these safety protection devices and perform regular maintenance and inspections to ensure their normal operation and safety.
