Types of Elevators-Home Elevators

Construction projects can take many months or even years to complete. You must select the right materials and structure design for your construction project. Before adding any additional items to a building, you must first consider the foundation.

You should consider how the people will access each floor when building multi-story buildings. While stairs are the obvious choice for multi-story buildings, it is wise to consider how people will access each floor. 

What’s an Elevator?
An elevator is an open- or closed-type platform used to lift or lower people or goods from upper or lower floors. It was not a requirement that story buildings have elevators in the past. Because they are expensive to install and maintain, many real estate investors avoided installing them.

How Law Has Influenced Elevators
Elevators became common only after the Americans with Disabilities Act, which was passed in 1990. This legislation prohibits discrimination against persons with disabilities. All buildings with two or more stories must be equipped with elevators. It makes it easier for those with disabilities to access multiple floors.

How Elevators Works
Since the 1800s, elevators have not changed in any significant way. Elevators are still used to transport people between floors. Most elevators use the Otis Safety System, which has been in use since the 1850s.

Modern lift part suppliers have modern control systems that are safer and faster. Elevators will use a counterweight and 40% of their maximum rated loads to balance the car in most cases.

The counterweight’s main function is to lower the motor’s weight and keep the elevator under control. Steel is used to make the car elevator strong and durable. A spanned side-to-side elevator shaft holds the pulley that is used for the hoist cable in place. The spin is controlled by a series of steel beams, which are located above the elevator car.

Modern elevator cars have advanced technology. Many have phones that enable the occupant to call 911 in an emergency. Some have trap doors that allow for escape in emergencies.

According to the building’s capacity and the duties that will be performed, elevators are fitted in buildings according to their needs. Some buildings will have large elevators that can transport heavy cargo to different floors. To allow emergency patients to move and enter hospitals, some elevators can open on both sides.

Elevator Types

In the past, elevators were controlled from a central machine room. There are now some elevators that don’t require a machine room, as they come with an integrated safety mechanism. There are four types of elevators available: machine-room-less (machine-room-less), hydraulic (traction), and vacuum.

1. Traction Elevator, Geared or Gearless

There are three types of gearless and geared Traction elevators:

Traction Elevator

The elevator’s ropes pass above an electric motor attached to a wheel located above the shaft. Ropes are used to lift and lower the elevator car. It can be used in high-rise and mid-rise applications, and it can travel faster than hydraulic elevators.

This system is similar to other types of elevators. It uses a counterweight that removes the car’s weight so the motor can move the load more efficiently.

Geared Traction Elevator

A motor with an attached gearbox is the heart of a geared elevator. The gears are used to drive the wheel that moves ropes. This type of elevator can reach speeds up to 500 feet per hour. It can travel a maximum distance of 250 feet.

Gearless Traction Elevator

The gearless elevators do not have speed regulation and don’t even have gear. They can travel up to 2,000 feet per hour and move at speeds of up to 2,000 feet. They are the best choice for skyscrapers.

2. Hydraulic Elevator

A piston is usually placed at the bottom of hydraulic elevators to support them. This is used to propel the elevator car upwards while the electric motor pushes hydraulic fluid down the piston. The valve releases hydraulic fluid from the piston when the elevator is ready to go down. This type of elevator can travel at a maximum speed limit of 200 feet per minute and is most commonly found in buildings with 2-8 stories. Here is another breakdown of hydraulic elevators.

Roped Hydraulic Elevator

This type uses both ropes as well as a piston to increase the elevator car’s motion. It can travel approximately 60 feet.

Conventional Hydraulic Elevator

It is designed with an elevator pit and has a sheave running beneath the pit’s floor. The pit holds a retracting piston as the elevator drops. A conventional hydraulic elevator may need a deeper hole to accommodate a collapsing, telescoping piston. It can travel approximately 60 feet.

Hydraulic Elevator with Hole

The Hole-less Hydraulic Elevator works in the same way as the traditional one but doesn’t need a sheave or hole below the pit. The pit’s base is equipped with telescoping pistons. These pistons enable the elevator car to travel 50 feet. A design with non-telescoping pistons is also available, but it can only travel up to 20 feet.

Hydraulic elevators are more popular than other types of elevators because they are easier to set up and require less maintenance.

Hydraulic elevators use more energy because they have an electric motor that works against gravity. Hydraulic fluids should be checked regularly as a small leak can easily cause a catastrophe or pose an environmental danger.

3. Machine-Room-Less Elevator (MRL).

Most elevators have a machine room above the elevator shaft. This type of elevator features a machine in the override area. It can only be accessed from the top of an elevator car when maintenance is needed. This type of elevator is limited to a distance of 250 feet and can travel speeds up to 500 feet per hour.

MRL elevators have been gaining popularity in mid-rise buildings due to their energy conservation and need for less space during construction.

4. Vacuum (Air Driven Home Elevator)

Vacuum elevators were introduced to elevator users in 2005. They do not require a pulley or cable system to work. These Air-Driven elevators work according to the laws of physics. This lift system is made of polycarbonate and aluminum materials. It operates in a sealed vacuum. The elevator car’s air is what allows for movement.

The system lowers the pressure above the tube by pressing the up button. This forces the air pressure below the tube to push it upwards. As you descend, the pressure below the tube is reduced, which causes it to move down.

This type of elevator can be found in three models. They are available for single or triple passengers, and can also accommodate wheelchair-accessible users.

How to Select an Elevator That Best Meets Your Needs

Elevators can be expensive investments. It is important to weigh all aspects when choosing the right one for you. A large MRL elevator cannot be installed in an apartment building of medium size. First, assess the building to determine the purpose of the elevator. These are some factors to be aware of:


Different elevators can be of different sizes and have different functions. Passenger elevators can carry up to 10,000 pounds. The majority can hold between 2,500 to 5,000 pounds. Some elevators may need special functions depending on the building. For example, space to hold stretchers in a hospital.


Freights can be heavy and require special elevators to transport them. Freight elevators can hold up to 20,000 lbs.


Many people confuse service elevators and freight elevators. Regular passenger elevators that are used by employees in buildings are called service elevators. These elevators are used to offer employees a faster way to move from one floor to another without disrupting customers or guests.

Residential or Commercial

Commercial elevators can generally accommodate more people than residential ones. Because they are less popular than commercial elevators, some residential elevators can hold only one person.


Dumbwaiters can be described as small elevators that are used for transportation purposes. A dumbwaiter is useful for moving food and dishes between floors in restaurants.

Final Thoughts

You must understand the building’s dynamics before installing an elevator in a multi-story building. Do you want to install an elevator in a commercial or residential building? It is also important to know the cost of an elevator for your structure. Elevators can be a costly investment but the ease of use and convenience is often a compelling reason to add them to your next building.
