The general concept of both semi and fully automatically lifts is obvious. It is known that the word semi-automatic means operated partly automatically and partly by hand so the human element would be involved in the operating process while on the other hand fully-automatic lift means designating a system, device, or machine whose function is completely automatic for example a firearm that loads itself and fires continuously.
But when it comes to lifts what are the technical DIFFERNCE BETWEEN SEMI AND FULLY AUTOMATIC LIFTS?
Know more about THE DIFFERENCE BETWEEN SEMI AND FULLY AUTOMATIC LIFTS in the upcoming sections of the article.
Automatic elevators and semi automatic elevators
Both automatic and semi-automatic elevators share the same basic mechanisms for lifting and lowering the car. However, they differ in how passengers interact with the doors and call buttons.
Automatic Elevators:
Doors: Open and close automatically when the car arrives at your desired floor, offering effortless entry and exit.
Buttons: Passengers simply press buttons inside the car and on the landing to select their destination.
Benefits of automatic lifts
- Convenient and user-friendly, especially for people with disabilities or carrying heavy loads.
- Faster service as passengers don’t need to wait for doors to open and close manually.
- Enhances accessibility and improves building management.
Drawbacks of automatic lifts
- Can be more expensive to install and maintain than semi-automatic elevators.
- May seem impersonal or even intimidating to some users.
Automatic lifting
Elevator magic? Not quite! Automatic lifts rely on a brain (controller) and muscles (motor). The controller receives your floor request, calculates the direction, and sends signals to the motor. The motor pulls cables connected to a counterweight, either raising or lowering the car. Safety sensors constantly monitor speed and position, triggering brakes if needed. All seamless, all automatic, for a smooth ride every time.
Semi-Automatic Elevators:
Doors: Passengers need to press a button to open and close the car and landing doors manually.
Buttons: Similar to automatic elevators, passengers press buttons to select their desired floor.
Benefits of semi lifts
- Generally cheaper to install and maintain than automatic elevators.
- Provide a sense of control for some users who prefer manual operation.
Drawbacks semi lifts
- Less convenient and require more physical effort, especially for older people or those with disabilities.
- Slower service as opening and closing doors manually takes time.
- Less accessible and may discourage use by certain individuals.
Ultimately, the choice between automatic and semi-automatic elevators depends on several factors, including budget, building type, user demographics, and desired level of accessibility – Know more bt contact us
Elevator door techniques
The one significant and most noticeable distinction is the door. So exactly to what length are they different?
We have to take a brief look at the journey the lift took through history in order to get to the diverse forms and shapes it’s on in the present. To do so we need to get back to the Pre-industrial era when the earliest known reference to a lift is in the works of the Roman architect Vitruvius, who reported that Archimedes built his first lift probably in 236 BC. Some sources from later historical periods mention lifts as cabs on a hemp rope powered by hand, animals or sometimes water-driven mechanisms at this time they were called hoists.
Now if we jump ahead to 1800 during which the modern lift was developed. These crude lifts slowly evolved from steam driven to hydraulic power. The first hydraulic lifts were designed using water pressure as the source of power. Their development was led by the need for movement of raw materials including coal and lumber from hillsides. The technology developed by these industries and the introduction of steel beam construction worked together to provide the passenger and freight lifts in use today.
The first electric lift was built by the German inventor Wener Von Siemens. In 1887, an electric lift with automatic doors that would close off the lift shaft was patented. This invention made lifts safer.
In 1889, the first commercially successful electric lift was installed.
Many changes in lift design and installation were made by the great advances in electronic systems during World War II. We can see lifts are becoming less dependent on human contributions and more on the machine. As mentioned earlier the most obvious difference between the most common lifts that are being used nowadays is the door since it’s the first thing you notice when you enter a building and see a lift.
LIFT DOORS
The main function of a lift door is preventing riders from falling into the shaft. They have two major types, semi-automatic and automatic doors. The semi-automatic doors are normally opened and closed manually using hands, and automatic doors are the standard type of doors found in modern day’s lift, usually powered by a door operator.
SEMI-AUTOMATIC
Imagine a regular room door that is normally opened and closed by using hand it is like that but the door is heavier and it would only open if your room was there. since coming in or out of an lift is not as easy as coming in or out of your room we come to the reason why the door is called semi-automatic to ensure the passenger’s safety some devices are added like a door lock a cam and electric magnets their main functions is to work together to ensure that the door never opens until it reaches a floor so the door won’t open while the lift isn’t there as well as to never move the lift as long as the door is open. The semi-automatic door also has a door closer to ensure that the door is well closed. There is also an addition folding door that is often added to the lift car from the inside that folds open and closes automatically for more safety reassurances.
Automatic door elevator
Automatic door elevators are the standard nowadays. They are much more convenient and safer than elevators with manual doors.
Automatic door elevator are typically made of metal or glass and slide open and closed electronically. They are equipped with safety sensors that prevent the elevator from moving if the doors are not fully closed.
There are two main types of automatic elevator doors: landing doors and car doors.
- Landing doors are located at each floor of the elevator shaft. They open and close automatically when a passenger calls the elevator or when the elevator arrives at a floor.
- Car doors are located on the inside of the elevator car. They open and close automatically when the elevator arrives at a floor.
The fully automatic lift lowers the risk of accidents caused by the human factor however, they might be considered by some users to be more complicated and power dependent than the semi-automatic but this shouldn’t be a problem in a well-installed lift with high-quality components which is usually the case because otherwise, they won’t pass any inspections. And in the end, the world is not new to the automatic lift it has been around for years and they’re becoming the most common.
Lift automatic doors vs semi automatic door
When it comes to elevators, the doors play a crucial role in ensuring smooth passenger flow and safety. But not all lift doors are created equal! Let’s delve into the world of automatic and semi-automatic doors, exploring their distinct mechanisms and functionalities.
Lift Automatic Doors
These modern marvels offer ultimate convenience and accessibility. Imagine stepping into a lift and the doors magically sliding open, welcoming you in. That’s the magic of automatic doors!
Mechanism of Lift Automatic Doors
- Sensors: Clever sensors detect the arrival of the lift at a floor and the presence of passengers inside or waiting outside.
