CONSTITUTION: A turbo high speed door comprises a frame(10), multi-refraction type isolating plates(20), vertical guide rails(30), double swirl rails(40) and a lifting device(50). The multi-refraction type isolating plates are refracted freely. The vertical guide rails are installed in the frame. The vertical guide rails guides by contacting to both sides of the isolating plates for moving the isolating plates upward and downward freely. The double swirl rails are installed in the frame and rolled double rail plates in a swirl shape by connecting with the guide rails for guiding the isolating plates not to be bumped each other. The lifting device is installed in the frame. The lifting device moves the isolating plates upward and downward forcibly. |
