Is the edge type applicable to the fire-resistant rolling shutter door in some special occasions, such as aircraft hangar, large garage, etc., where the span is very large, so the common fire-resistant doors and steel fire-resistant rolling shutter doors are difficult to do such a large scale, this time, it highlights the characteristics of fire-resistant rolling shutter door, so the design of fire-resistant rolling shutter door has a great development. There are several pages in the structure of side fire shutter. When the shutter is closed, the self weight will make the falling speed too fast or even the motor brake fails, causing an accident. And the horizontal opening and closing operation mode of the horizontal level of the transverse steel fire shutter door. When the span increases, only the number of color plates will increase. The length of the curtain plate and rolling is a constant. The transverse steel fire shutter door has two rollers, the driven shaft, and the other is used for the auxiliary shaft wheel, which is installed at the end of the driving shaft and the auxiliary shaft. The shutter opening and closing are through the curtains at both ends of the rotary switch of the wheel on the driving shaft The plate chain shaft realizes that the top of the curtain plate is equipped with rolling bearing, and the shutter is operated by connecting the rolling bearing guide rails arranged horizontally to the curtain plate to realize that the rolling guide channel steel and angle steel are commonly welded.
because the transverse steel fire shutter door is operated horizontally, when the span of the tunnel door is very large, auxiliary driving device can be added in the middle of the tunnel door, so as to achieve the purpose of sectional driving. Because the operating transverse steel fire-proof rolling shutter door is realized in the rolling guide rail of the rolling bearing and the rolling friction coefficient is small, the motor power of the same weight transverse steel fire-proof rolling shutter door needs far less than that of the ordinary steel fire-proof rolling shutter door, and the transverse steel fire-proof rolling shutter door can easily realize multi-level transmission, so the space of the transverse steel fire-proof rolling shutter door can be completed tens of meters or even tens of meters Hundreds of meters, for ordinary steel fire shutter door, it is unimaginable.
From the above points, it is not difficult to see why the side fire shutter door will be favored by many consumers, so it is necessary for some special large places to choose the side fire shutter door
