EM – Being familiar with automatic door elevators, consumers must still find it strange with manual door elevators. However, the operating mechanism of this type of door has a much longer history. And so far, how has safety technology for manual doors been applied and is there any difference compared to automatic doors?
The beauty of tradition and history
In the past, manual doors were mainly used in freight elevators (folding iron doors) or food elevators with sliding doors up and down.
When the first passenger elevators appeared, most of them were for the aristocracy or at high-class hotels. The design at that time was all manual doors, the door opening and safety control were completely manual by the “doorkeeper”.
Also because of this design, the elevator at that time was also called “the room going up”, because in addition to the function used to move, the car door was designed as aesthetically as the door of a luxury room, along with the newness of the most advanced equipment of the time and the feeling of “being served” made many people have nostalgia for this aristocratic experience.
When automatic door technology appeared, it gradually became a trend because of the ability to automatically close the door and save manpower to control the opening and closing of the door, and safer during use by controlling the safety latch. all when the elevator moves. Over the years, hand-opening door lifts have become “outdated” for a while.
Even so, it is only a pause because the design still offers an extraordinary allure to enthusiasts of architectural beauty, but the sharp carvings, the surprises hidden behind the doors, and the modern and luxurious space adaptation are all very unique features of manual door elevators.
Manual doors also do not limit the possibilities of creating space in the cabin, as the collections of famous Italian designers are inspired by classic Oscar-winning movies or unique architectural trends. unique: philosophy, neoclassical, … such as the collection “The Box” by designer Giulio Cappellini, “POP UP” by the famous architect duo Chiara Caberlon and Ermanno Caroppi from CaberlonCaroppi Studio, etc.

What’s the difference between manual doors?
The most common elevator doors today are automatic doors, central opening (Centre Opening – CO) or Side Opening – SO. But in order to install an automatic door elevator, the width of the pit must be wide because it needs area for the door.
Central opening automatic door is the most common type of door, there are also automatic sliding doors
However, with renovation or new construction projects that have a small area, narrow pit size, and not enough space to make automatic doors, manual doors will be effective.
Today’s technology is increasingly developing, safety features have been designed to be integrated into hand-opening door elevators to ensure safety during elevator operation as well as to solve some limitations of elevators. automatic door. This series of manual door elevators are mainly used in home elevators.
Safety mechanism of manual door elevator
Compared to the structure, the manual door elevator is much simpler than the automatic door, if you look at it, it looks like a normal door opening. This also makes many consumers hesitate about the safety of this elevator line. However, the structure of safety parts has ensured about this, let’s find out the main parts of the elevator car door with manual doors:
– Door: Can be made of stainless steel frame glass or powder coated steel.
– Hinge system: To link the door and the cabin frame.
– Safety contact: The safety device ensures that the elevator only works when the door is completely closed.
– Safety latch: To ensure that the landing door can only be opened from the outside when the cabin stops at that floor, avoiding the case of people/objects falling into the well.
– Infrared curtain: To ensure that there are no obstacles crossing the door, if there is, the elevator will have a warning and do not move to ensure the safety of users. There are 2 types: designed in a 2-beam jar and vertical blinds throughout the length of the door.
Manual door elevators often combine stainless steel frames with glass, the structure becomes elegant and harmonious with many architectural styles.
How the manual door lift works:
– Press the button to call the elevator at the landing door
– When the cabin is on the same floor, instead of waiting for the door to open automatically like an automatic door, you need to open the door manually like a normal door
– After entering the cabin, close the landing door
– Close the cabin door
– Select the floor you need
– When the cabin reaches the floor, open the cabin door, open the landing door, step out and close the door
Advantages of manual door lift:
– The biggest advantage of this type of elevator is that it can make the elevator door wider than the automatic door, even if the pit is narrow, it is not possible to do the automatic door, the manual door solution is still completely feasible.
For example: The elevator door requires a minimum width of 60cm to be used (human shoulder width is all from 50cm or more), but to make the elevator door 60cm wide with automatic doors, internal shaft should be at least 1300mm.
Equally important is that with the safety latch of the lift door opening, we can avoid situations where the elevator cabin moves when the automatic door is not closed.
Manual door elevators can optimize space, suitable for renovated houses that install more elevators
In the architecture of the house, if the elevator is not cleverly designed, it is easy to become a mechanical block “out of tune” from the general architecture of the space by the block structure and metal materials. However, with the manual door elevator, most of the problems are eliminated because the design is similar to a regular room door, which can combine rich materials and textures for both the landing door and car.

Even the minimalist style house, the manual door design easily becomes harmonious with the space.
Disadvantages of manual door lifts:
Even the name of this elevator line has shown its limitation, that is, the elevator needs to manually open the door, not having the ability to fully automatically open the door. This can cause difficulties for special subjects such as young children, the elderly, and the disabled who will need help during use. Or strangers who use this type of elevator for the first time will also have a certain confusion.
Based on the advantages and disadvantages of the manual door elevator line, consumers can consider choosing an elevator design that suits the needs of their family. Regardless of the type of elevator, users should choose a reputable elevator supplier, learn about the safety technologies integrated into the product, and complete inspection, maintenance and repair services enough to ensure the safe and convenient use of the elevator.
