This vertical construction has led to elevators playing a critical role in human and freight transportation. Smart elevators, increasingly replacing traditional elevators, are equipped with technological innovations, aiming to maximize user experience and efficiency. In this article, we will examine the concept of smart elevators, their historical development, types, structure, working principles, selection criteria, usage rules, and maintenance processes in detail.
History of Smart Elevators: Revolution in Vertical Transportation from Past to Present
The history of smart elevators actually dates back to the invention of the elevator itself. Although the first elevators were invented in the 3rd century BC by Archimedes using simple lever systems, the foundations of modern elevators were laid in the 19th century. The first steam-powered elevators were an important step in freight transportation, but were not considered safe enough for human transport.
The turning point that solved the safety problem came in 1852 when Elisha Graves Otis invented the "safety brake." This invention prevented the elevator car from falling if its rope broke, paving the way for elevators for human transportation. Otis's invention can be considered a starting point for the history of smart elevators as well.
With the widespread adoption of electric elevators in the early 20th century, a new era began in vertical transportation. The first automatic elevators emerged in the 1920s, increasing efficiency by eliminating the need for an operator. However, these first automatic systems were not yet comparable to today's types and features of smart elevators.
Truly smart elevators emerged in the early 21st century with the development of computer technologies and sensors. This new generation of elevators not only performs vertical transportation but also offers significant improvements in areas such as energy efficiency, safety, comfort, and user experience.
Types and Features of Smart Elevators: Solutions for Every Need
The types and features of smart elevators vary depending on the purpose of use, building type, and user expectations. In general, we can classify smart elevators as follows:
- Destination Dispatch Elevators: In this system, users specify the floor they want to go to before entering the elevator via buttons or touch screens. The system directs the most suitable elevator using algorithms and minimizes waiting times. These types of smart elevators significantly increase efficiency, especially in high-traffic high-rise buildings.

Structure of Smart Elevators: Where Technology Meets Architecture
The structure of smart elevators, while having basic components similar to traditional elevators, is enriched with technological innovations. The basic building blocks are:
- Elevator Car: The section where users and loads are transported. In smart elevators, cabins are made more comfortable and safer. Interior designs, ventilation systems, lighting, and information screens enhance the user experience.
- Hoistway: The vertical space in which the elevator car moves. Rails, counterweight system, safety systems, and sensors are located inside the hoistway.
- Machine Room (or Machine Room-Less Systems): In traditional elevators, the machine room contains the motor, control panel, braking system, and other mechanical components. In smart elevators, machine room-less (MRL) systems are becoming increasingly common. In MRL systems, the motor and control equipment are placed inside the hoistway or on top of the cabin, providing flexibility in building design and increasing energy efficiency.
- Control System: The control system, which forms the basis of the working principle of smart elevators, manages all movements and functions of the elevator. Through advanced microprocessors, software, and sensors, it performs tasks such as traffic analysis, floor selection, speed control, safety monitoring, and remote management.
- Sensors: Sensors, playing a critical role in the structure of smart elevators, continuously monitor cabin position, speed, load, door status, temperature, vibration, and other parameters. This data is transferred to the control system, ensuring the elevator operates safely and efficiently.
Working Principle of Smart Elevators: Synchronization of Efficiency and Safety
The working principle of smart elevators is based on the harmonious operation of complex algorithms, sensors, and control systems. The basic steps can be summarized as follows:
- Call Detection: Users make an elevator call by pressing floor buttons or specifying their floor in destination dispatch systems. Sensors detect these calls and transmit them to the control system.
- Traffic Analysis: The control system evaluates the traffic flow inside the building by analyzing data from sensors (cabin positions, directions, loads, call density, etc.).
- Elevator Assignment: Algorithms assign the most suitable elevator to the call based on traffic analysis. In destination dispatch systems, calls going in the same direction are grouped, optimizing elevator routes.
- Speed and Position Control: The control system precisely adjusts the speed and position of the elevator car using the motor and braking system. Sensors continuously monitor the car's movement and provide feedback to the control system.
- Safety Monitoring: Sensors detect any abnormalities that may affect elevator safety (overload, door malfunction, vibration, etc.) and alert the control system. In emergencies, safety protocols are activated, and the elevator is safely stopped.
- Remote Management and Maintenance: The control system continuously records elevator performance data and transmits it to the remote monitoring system. Maintenance personnel can analyze this data to detect potential malfunctions in advance and plan maintenance processes more effectively.
Smart Elevator Selection: Finding the Most Suitable Elevator for Your Needs
Smart elevator selection depends on various factors such as building type, purpose of use, traffic density, energy efficiency expectations, budget, and user needs. Some important points to consider when choosing the right elevator are:
- Building Type and Height: Different types of smart elevators may be suitable for low, medium, or high-rise buildings. In high-rise buildings, high-speed elevators and destination dispatch systems are preferred, while simpler and energy-efficient models may be sufficient in low-rise buildings.
- Traffic Density: The expected traffic density of the building is an important factor in determining elevator capacity and speed. Destination dispatch systems and multi-elevator groups should be considered in high-traffic buildings.
- Energy Efficiency: To reduce energy costs and minimize environmental impact, models with energy-efficient smart elevator features should be preferred. Features such as regenerative braking, LED lighting, and sleep mode contribute to energy saving.
- Accessibility for People with Disabilities: To ensure that people with disabilities can also use elevators comfortably, accessible types and features of smart elevators should be considered.
