special Fire shutter door (inorganic cloth folding hoisting type) from the inorganic hoisting Fire shutter screen uses the door roller as the power source, and uses bearings, bearing seats and bearing support rotating shafts to improve transmission efficiency. The lifting belt is used to lift the Fireproof rolling shutter door curtain. Under the action of lifting, the curtain cloth folds and lifts to the top of the hole. Under the condition of smoke, temperature and fire alarm, the top of the curtain cloth drops to the ground, and the whole hole is closed by folding and stretching to a flat surface. When the opening is infinite, a power (door rolling machine) or transmission device will be added at a certain distance, solving the problem that the opening width is too large and the terrain scroll and rolling curtain can not be used normally. At the same time, it has all the functions and characteristics of inorganicspecial fire shutter door (Dual track inorganic Bucky), reliable operation, smooth opening and closing operation, fast speed, low noise characteristics.
Fire shutter with Fire prevention function for industrial and civil buildings. At the same time, it is suitable for a variety of unconventional openings with large spans, curves or corners.
（1） Fire shutterThe opening and closing transmission device can be installed on the left or right side of the indoor or the left or right side of the outdoor according to the installation conditions and use requirements.
（2) When adopting the Fire shutter, the position of the transmission mechanism should be considered to avoid collision with the building components.
