The Mitsubishi “Spiral escalator”

In 1985, the Japanese based Mitsubishi conglomerate launched the first ever spiral escalator product on the market. A tremendous engineering effort was put in its development, industrialization and commercialization.

Despite the fact it is an engineering triumph and a mechanical marvel, the product has some disadvantages which prevents it from reaching its expected success.

The complexity of the machine makes it heavy and expensive to shift and sell, the on-site installation is time consuming and it has a highly demanding maintenance schedule for long term usage. Until present the company has sold approximately 100 machines worldwide.
