The Levytator is the world's first escalator capable of following freeform curves. It has been developed by Jack Levy, an Emeritus Professor of Mechanical Engineering at City University London.
This video shows a working model and computer simulations.
Unlike traditional escalator designs, where redundant steps move underneath those in use, the Levytator uses a continuous loop of curved modules, so the cost per usable step is reduced. The steps can follow any path upwards, flatten and straighten out, and descend once more, all with passengers on board.
With the Levytator, architects are able to create escalators in whatever shape they want -- as a ride around a theme park or on top of an existing staircase, for example.
The Levytator has been patented in the UK, Europe, the USA and China, and City University London is now seeking partnerships with architects and manufacturers to take this exciting innovation to market.
