Lifts and Escalators: How Cities Move Vertically

Modern cities are not just spread across land—they are stacked. Offices rise into the sky, transport systems extend underground, and shopping centres stretch across multiple levels. None of this works without one critical system: lifts and escalators. They are the mechanisms that make vertical and multi-level movement possible, shaping how buildings are designed, how people move, and how businesses operate.

At a basic level, lifts (elevators) and escalators solve a physical problem: how to move people efficiently between levels. But in doing so, they unlock entirely new forms of urban development. High-rise buildings, for example, would not exist in their current form without reliable lift systems. The ability to move people quickly between dozens of floors allows cities such as Dubai, New York, and Shanghai to build vertically rather than expand outward.

Lifts are central to commercial real estate. Office towers depend on them to function. Without efficient lift systems, tenants would struggle to access upper floors, reducing the value of the building. Developers therefore invest heavily in lift design, capacity, and speed. In skyscrapers, multiple lift banks are often used to manage traffic, sometimes with express lifts serving specific ranges of floors.

Escalators play a different but equally important role. In spaces such as shopping centres, airports, and transport hubs, they enable continuous movement of large numbers of people. Supermarkets and retail complexes use escalators to guide customer flow between levels, often placing key products or services strategically to influence movement patterns.

Airports offer a clear example of how these systems operate at scale. Large terminals rely on a combination of lifts, escalators, and moving walkways to move passengers efficiently. Facilities such as Heathrow Airport and Dubai International Airport integrate these systems into complex layouts that handle millions of यात्रers each year. Without them, passenger flow would slow significantly, affecting the entire travel experience.

Accessibility is one of the most important aspects of lift systems. For people with mobility challenges, lifts are not a convenience but a necessity. Regulations in many countries require buildings to provide accessible routes, ensuring that public and commercial spaces can be used by everyone. This has shaped building design, making lifts a standard feature rather than an optional addition.

The business behind lifts and escalators is global and highly specialised. Companies such as Otis Worldwide, Schindler Group, and KONE design, manufacture, install, and maintain these systems. Their operations span continents, supporting infrastructure in cities around the world.

Maintenance is a critical part of the system. Lifts and escalators operate continuously and must meet strict safety standards. Regular inspections, repairs, and upgrades are essential to ensure reliability. This creates ongoing service businesses that generate revenue long after installation.

Technology is transforming how these systems work. Modern lifts use advanced control systems to optimise movement, reducing waiting times and energy consumption. Some buildings use destination control systems, where passengers select their floor before entering, allowing the system to group journeys more efficiently. In high-rise buildings, double-deck lifts and high-speed systems enable rapid vertical transport.

Escalators have also evolved, with improvements in energy efficiency and safety features. Sensors can adjust speed based on usage, and designs continue to adapt to different environments, from metro stations to large retail spaces.

The economics of lifts and escalators extend beyond installation. They influence how buildings are valued and used. A well-designed lift system can increase the usability of upper floors, making them more attractive to tenants and businesses. In retail environments, escalator placement can affect customer behaviour, guiding foot traffic and influencing purchasing patterns.

Globally, the role of these systems varies by context. In dense urban centres such as Hong Kong and Tokyo, lifts and escalators are essential to daily life, supporting high-density living and transport systems. In developing cities, expanding infrastructure often includes installing these systems in new commercial and residential developments, reflecting urban growth.

There are also less visible impacts. Emergency evacuation planning, energy consumption, and building design all depend on lift systems. In some cases, lifts are integrated into smart building systems, connecting with security, lighting, and climate control.

Seen as a system, lifts and escalators connect architecture, engineering, urban planning, and human behaviour. They enable vertical cities, support accessibility, and shape how people interact with spaces.

Returning to the question—how do cities move vertically—the answer lies in these interconnected systems. Without lifts and escalators, modern urban life would look very different. Buildings would be shorter, movement slower, and accessibility more limited.

From office towers and airports to shopping centres and transport hubs, lifts and escalators are part of the infrastructure that allows cities to function at scale.
