A primary classification for automatic elevator doors is to classify them into automatic cabin and floor doors. These automatic doors have different types and are divided into two general categories: Telescopic automatic doors Central automatic doors Different types of these doors include parts such as contacts, shoes, door seals, slats and frames. In the following, we will further examine each of these doors and their functions.
Automatic Lift Door Telescopic
In general, the design and construction of automatic doors for elevators should be based on the type of use in the building. Accordingly, in some buildings, it is necessary to open and close the elevator door only on one side based on the location of the elevator and the available space. Telescopic automatic doors have the same structure and open and close only from one side. These doors are used for both elevator cabin doors and floors, and when the cabin is standing on each floor, the cabin doors and floors will be opened and closed automatically from one side.
Telescopic automatic doors are used in single-door elevators and have only one panel. The use of these automatic elevator doors is usually very useful for limited spaces and narrow corridors. Usually, the time these doors stay open can be set between 0 and 40 seconds using the remote control. The opening and closing speed of the telescopic doors of the elevators is also adjustable between 700 mm/s.
Automatic Central Doors
Another category of doors that are used as automatic doors for elevators are central doors. These doors are among the most widely used automatic doors, which are used especially in larger buildings with open space. These doors are effective for larger cabins and are known as automatic doors of elevators with two door hinges. The doors of the central elevator have two separate hinges.
To open, these doors are opened in the opposite direction and when they are closed, they are tangentially placed together. The basis of the operation of these automatic doors in elevators is based on the correct optical operation of the elevator. As a result, these doors are opened and closed by operating the elevator door visually. These doors can be used in wells that are very wide.
