What Are the Types of Elevators?
With the technological changes and advances of our age, elevators have become an indispensable part of our lives, meeting a wide variety of needs.
So, what comes to mind when we think of elevators? For most of us, the first thing is probably the elevators we use in our residential buildings. However, there are many different types used across various settings. These can be listed as follows:
1) Electric Elevators:
These elevators operate when the drive motor receives a command from the control panel and moves the cabin in the required direction. The cabin works together with a counterweight. The cabin and counterweight move up and down through the friction between the steel ropes and the traction sheave. The cabin and counterweight are approximately equal in weight.
2) Hydraulic Elevators:
In hydraulic elevators, lifting is performed by an electrically driven pump that supplies hydraulic fluid to a lifting mechanism acting directly or indirectly on the cabin. Downward movement occurs under the cabin’s own weight.
The machine room is generally located at the lowest landing level. It contains an oil reservoir, the hydraulic power unit mounted on it, the control panel, and the hoses through which the hydraulic fluid flows. The elevator shaft contains the cabin, the counterweight if fitted, the cylinder and piston system, the suspension system, and the buffers.
3) Freight Elevators:
These elevators are installed for use in factories, warehouses, or parking facilities. They operate reliably under demanding conditions.
Designed exclusively for transporting goods, their cabin or platform dimensions and motor power are determined by the maximum load to be carried. Freight elevators are designed to withstand the most demanding conditions in the building where they are installed and are available in capacities ranging from 500 kg to 10,000 kg. Their drive systems can be traction or hydraulic.
4) Stretcher Elevators:
These elevators provide comfortable and safe transportation for patients. They are available with load capacities of 1,600 kg, 2,000 kg, and 2,500 kg.
Their distinguishing features are comfort and safety. Precise floor leveling allows stretchers to enter and exit smoothly without jolting. Additional features include provisions for power failures, carefully adjusted lighting, antibacterial measures, and stainless steel components.
5) Vehicle Elevators:
These elevators are used where rooftop and basement areas of buildings serve as parking facilities. Vehicle elevators can have a load capacity of 3,000 kg.
6) Panoramic Elevators:
These elevators are used outdoors, in shopping centers, and at train stations. Depending on the building’s architecture, they can be equipped with electric traction or hydraulic drive systems.
7) Accessibility Elevators:
These elevators are designed for elderly people, people with disabilities, and wheelchair users. They are also referred to as stair lifts.
They differ from other elevators through features such as wider entrances, standard automatic doors, horizontally arranged control panels positioned at a lower height, and buttons with raised markings.
8) Dumbwaiters:
These elevators are generally used in hotels, restaurants, and villas to transport plates, glasses, and trays from the kitchen to the dining floor. Designed exclusively for carrying goods, they are too small for people to enter.
These service lifts can be considered small freight elevators and are available with load capacities ranging from 50 kg to 250 kg.
9) Inclined (Horizontal) Elevators:
Horizontal elevators are passenger transportation systems commonly used in airports, hospitals, and university complexes in developed countries.
10) Machine-Room-Less Elevators:
Machine-room-less elevators are used particularly in passenger terminals, department stores, shopping centers, and educational, cultural, and healthcare facilities.
They offer significant advantages for designers, builders, and building owners, especially in taller commercial buildings with heavier passenger traffic. In these elevators, the drive machine is located above the cabin or within the elevator shaft.
