Sliding Doors
Sliding Doors
A door in which the panel or panels slide open and closed on a hanger mechanism that is usually mounted above the doorway opening. A sliding door system can have either a single or double (bi-parting) panel configuration.
The operation of a sliding door is the most basic of all door types, the guiding is realized by a track in which the rollers connected to the door leaves are running.
A. Sliding Doors with Electric Actuator
The synchronization between the primary and secondary door leaf is realized by means of a synchronization belt or by means of a spindle and spindle nuts. The spindle has right and left turn thread for opposite door movements, both opening or both closing. The movement of the door leaves is by means of electric motor which is connected to one of the pulleys at the belt driven type and to the spindle at the spindle type.
B. Sliding Doors with Pneumatic Actuator
The movement of the door leaves is by means of a linear pneumatic cylinder which is connected to one of the door leaves (primary). The synchronization between the primary and secondary door leaf is realized by means of a synchronization cable or belt or by means of a spindle and spindle nuts. The spindle has right and left turn thread for opposite door movements, both opening or both closing. This door system can have as well a double leaf as a single leaf configuration.
Sliding Doors Advantages:
Simple system, short opening and closing times
Range of application:
Used on metros and shuttle trains, if there are no critical ambient requirements – used mainly in Asia and in the USA.
