UK researcher develops world's first freeform curved escalator

A researcher from City University London has developed an elevator that, unlike traditional designs, uses a continuous loop of curved modules. This enables it to follow any path upwards, flatten and straighten out and descend once more.

The system, known as the 'Levytator', has been developed by Jack Levy, an Emeritus Professor of Mechanical Engineering at City University.

According to Levy, the system can be arranged in any configuration – as a DNA-esque double helix in a science museum, for example – and also offers several practical advantages at a cost that is similar to a conventional unit.

"As all of the steps can be accessed from above, maintenance can be carried out much more easily," says Levy. "It also means that no excavation is required when installing the Levytator. This could be particularly useful in the heritage sector, where the system could be placed on top of a grand staircase in a listed stately home, providing better access for elderly and disabled visitors, but not destroying the fabric of the building."

David Chan, director of City's Centre for Information Leadership and consultant to the project, adds: "The Levytator opens up new possibilities for architects in hotel, airport, museum, theme park and commercial building design. As it can carry twice as many people as a traditional escalator, but at a comparable price, it will also be an attractive financial proposition."

The technology has been patented in the UK, Europe, the USA, and China, and City University London is now actively seeking strategic partnerships with architects and manufacturers to take the Levytator to market.
