Curved escalators are among the most impressive engineering achievements in modern passenger transportation. Unlike traditional escalators that travel along a straight path, curved escalators, also known as spiral escalators, are designed to operate along a curved trajectory, creating a distinctive architectural feature for shopping malls, hotels, airports, and high-end buildings.

In addition to outstanding aesthetic value, this specialized type of escalator demonstrates the manufacturer’s technological capabilities and engineering expertise. So, how do curved escalators work, what advantages do they offer, and why are they still considered one of the most complex escalator systems in the world?

What are curved escalators?

Curved escalators are one of the most specialized and complex types of passenger transportation systems. Unlike conventional escalator structures that move along a straight path, these escalators are designed with a curved trajectory, allowing passengers to move continuously along an arc or spiral path. They are commonly installed in high-end shopping malls, international airports, luxury hotels, and architecturally iconic buildings.

In addition to providing passenger transportation, spiral curved escalators also serve as an architectural centerpiece that enhances the aesthetic value of a building. For this reason, many developers consider them a solution that combines functionality with design artistry.

Why is spiral escalator technology considered special?

To manufacture a spiral curved escalator like the one shown, Mitsubishi must overcome many engineering challenges that are far more complex than those involved in conventional escalators. The guide rails, steps, drive chains, traction motor, and safety mechanisms must all be specially designed to match the curvature of the building.

In particular, each step must be able to adjust its position as it moves through curved sections while maintaining safe spacing, stability, and passenger comfort. Due to this level of complexity, only a limited number of manufacturers worldwide produce curved escalators.

Can only Mitsubishi manufacture curved escalators?

The answer is not entirely.

Mitsubishi is one of the most well-known brands in the field of curved escalators and has been involved in numerous iconic projects worldwide. Since the 1980s, Mitsubishi has researched and successfully commercialized curved escalator technology, becoming one of the most recognized names associated with this type of equipment.

However, this does not mean that Mitsubishi is the only manufacturer capable of producing this technology. In fact, several leading elevator and escalator groups worldwide have also developed similar solutions or have their own design capabilities for specialized projects. Nevertheless, the number of projects actually implemented remains significantly lower than that of Mitsubishi.

Mitsubishi is often considered a leading choice due to its extensive experience, large number of reference projects, and ability to customize solutions to meet specific architectural requirements.

Real-world projects using spiral escalators

One of the most famous projects featuring curved escalators is the Forum Shops at Caesars Palace in Las Vegas, USA. The project is widely regarded as an iconic example of curved escalator technology worldwide.

In addition, many high-end shopping malls in China, the UAE, and several European countries have adopted this type of escalator to create distinctive architectural features and enhance the customer experience. These projects demonstrate that curved escalators are not merely transportation equipment but also an integral part of modern commercial space design strategies.

At the Maidaru shopping mall, Shanghai, these two spiral escalators were manufactured by Mitsubishi, while the Shanghai Mitsubishi brand handled their installation and maintenance, similar to its role in the fastest and tallest elevator in China.

How much does a spiral escalator cost?

This spiral escalator is typically suitable for projects with special architectural requirements, where aesthetics are just as important as functionality. High-end shopping malls, entertainment complexes, luxury hotels, and international airports are among its most common applications.

However, the investment cost of spiral escalators is generally significantly higher than that of conventional escalators because each project requires customized design, manufacturing, and installation. Therefore, developers should carefully consider the architectural value provided against the actual investment budget.

Conclusion

When it comes to curved escalators, Mitsubishi remains one of the most widely recognized brands due to its extensive experience and large number of projects worldwide. However, the claim that only Mitsubishi can manufacture curved escalators is not entirely accurate. More importantly, manufacturers need to demonstrate strong design capabilities, practical experience, and the ability to meet the specific technical requirements of each project.

For projects that demand distinctive architecture and an enhanced customer experience, curved escalators remain one of the most impressive solutions available today. They can contribute unique value to a building and enhance the developer’s brand image.
