In order to provide the space that building various facilities for leisure and amusement, such as a hotel, owners could only once dream of, Mitsubishi Electric developed the world’s first spiral escalators. Carefully intermixing casino, and shopping mall. Mitsubishi Electric spiral escalators are vertical and rotational movements, an elegant arch is created utilizing one-and-only escalator technologies no other installed at the center of the casino, creating a massive company has been able to achieve. The three-dimensional motion creates an expansive panoramic view for users, and the open-ceiling space at the heart of the facility. There is a stage for street performances and the arching presence of the escalator innovative design transforms the area into an unprecedented architectural masterpiece. An artisan skill called Takumi (in contributes as an inspirational piece of the architecture, Japanese) is utilized, where the maker demands perfection and refuses to compromise down to the smallest detail. All of this producing a seemingly medieval atmosphere. to ensure satisfaction to the customer in the joy of ownership and welcome visitors with an experience that is exciting and unforgettable.

Breath-taking artistic design delivers added-value

Combined with highly advanced building design, spiral escalators enhance architectural structures by delivering added-value and artistic appeal. The unique "interior in motion" attraction produces a special space and time for tenants and visitors alike to enjoy. Installed in facilities such as museums or art museums, the escalators give a three-dimensional perspective to traditional buildings and exhibits, further confirming their high affinity in architectural design.

Escalators drawing an arc once said Escalators drawing arcs unique in appearance.

The rotational moment is complex in form, with the longitudinal movement closely intertwined. To accomplish this, although the concept had long existed around the world, to be physically impossible. it had not been successfully achieved. Then, in 1985, Mitsubishi Electric successfully developed what is now called the “Spiral Escalator.” Today, 31 years later, Mitsubishi Electric remains the only company to manufacture spiral escalators. There is a reason that this could At first glance, these escalators appear to have curvatures without any special features. But the arcing structures achieved use elaborate, sophisticated technologies only capable of being realized applying the design, only be achieved by Mitsubishi Electric. manufacturing, and installation skills of expert engineers.

Discovery of the Elaborate processing only possible Centralized motion method “Centralized motion method” principle using manual labor As spiral escalators require complicated three-dimensional movement, various Most curving escalators once proposed around the world were based on methods components must be processed into unique shapes such as curved trusses and steps for movement in a concentric circle. But none ever made it to market. Even though the speed of horizontal movement when creating a semi-circle is regular, Center point 2 with arch-like grooves. The complex shape of the track makes it one of the parts that requires a meticulous process utilizing intricate manufacturing technologies.

Horizontal rollers are installed on the outer-side of the chain, enabling the structure to manage the inward force generated by the arching Specialized installers assemble the truss by connecting up to 6,000 custom-shaped configuration. This enables the escalator steps to move along the fixed orbital parts. After installation, multiple quality assurance checks are carried out to ensure External step chain plane with high accuracy. that the finished product embodies Mitsubishi Electric quality in the most detailed Internal step chain areas.
