Hard fast rolling door, also known as aluminum alloy fast door, hard fast door, fast rolling door, is the latest anti-theft and heat-insulating metal fast door, which has high practicality and Reliability and safety; and simple and easy to operate.
Control system: It is composed of servo motor, reducer and power-off braking system. The overload capacity is also very strong. In places that require high-frequency opening and closing, it can work more than 3,000 times a day. It also has a high-resolution encoder with 2,000 lines, which can ensure that the door body is not prone to noise when running, and the door curtain and track are friction-free. .
Door curtain mechanism: It is composed of aluminum alloy door pieces, soft curtain door chains, load-bearing rubber strips, guide rails, etc. 1. The thickness of the door curtain is generally 1-200mm, and the surface is colored by an aerobic oiler. The standard colors are gray, aluminum alloy sand white and Chinese red. 2. After connecting the aluminum alloy pieces through the rubber strips, the service life of the connection between the soft curtain rubber strips and the aluminum alloy door pieces can reach more than one million times; 3. The design of the chain load-bearing method prevents the door curtain joint from experiencing great resistance. The sheet is not easily deformed and can maintain stability for a long time after long-term use. When the 4-door body is running, the guide pulley is installed on the inside of the aluminum alloy guide rail and slides. Even if it runs at high frequency, it will not make a lot of noise.
Hard fast rolling shutter doors are widely used in special places that need to open and close quickly to cut off air convection, shorten entry and exit times, and require energy conservation and environmental protection; if you need to learn more , welcome everyone to pay attention to the fast rolling door manufacturer.
