ThyssenKrupp to Test Brand New Elevator System in 2016

Travel News Asia Videos Podcasts Latest Travel News Asia Wednesday, 3 December 2014

ThyssenKrupp has placed linear motors in elevator cabins, transforming conventional rope-dependent elevator transportation in vertical metro systems.

Multi, as the company has called the elevator technology, increases transport capacities and efficiency while reducing the elevator footprint and peak loads from the power supply in buildings.

The first Multi unit will be in tests by 2016.

Multi is ThyssenKrupps latest offering in its extensive repertoire of elevator technologies. It allows multiple cabins in the same elevator shaft by applying the linear motor technology of the magnetic levitation train Transrapid to the elevator industry.

In a manner similar to a metro system operation, the Multi design can incorporate various self-propelled elevator cabins per shaft running in a loop, increasing the shaft transport capacity by up to 50% making it possible to reduce the elevator footprint in buildings by as much as 50%.

Using no cables at all, a multi-level brake system, and inductive power transfers from shaft to cabin, Multi requires smaller shafts than conventional elevators, and can increase a buildings usable area by up to 25%, considering that, depending on the size of the building, current elevator-escalator footprints can occupy up to 40% of the buildings floor space.

Although the ideal building height for Multi installations starts at 300 metres, this system is not constrained by a buildings height. Building design will no longer be limited by the height or vertical alignment of elevator shafts, opening possibilities to architects and building developers they have never imagined possible.

Multi is based on the concept of ThyssenKrupp Twins control system and safety features, but includes new features such as new and lightweight materials for cabins and doors, resulting in a 50% weight reduction as compared to standard elevators, as well as a new linear drive using one motor for horizontal and vertical movements.

Andreas Schierenbeck, CEO of ThyssenKrupp Elevator AG said, As the nature of building constructions evolve, it is also necessary to adapt elevator systems to better suit the requirements of buildings and high volumes of passengers. From the one dimensional vertical arrangement to a two dimensional horizontal/vertical arrangement with more than one or two cabins operating in each shaft, Multi represents a proud moment in ThyssenKrupps history of presenting cutting-edge transport technologies that best serve current mobility needs.

Operating on the basic premise of a circular system, such as a paternoster, Multi consists of various cabins running in a loop at a targeted speed of 5 m/s, enabling passengers to have near-constant access to an elevator cabin every 15 to 30 seconds, with a transfer stop every 50 metres.

Per year, New York City office workers spend a cumulative amount of 16.6 years waiting for elevators, and 5.9 years in the elevators. This data provides how imperative it is to increase the availability of elevators, Schierenbeck added.

A 2013 analysis of two-dimensional elevator traffic systems likens the present use of one cabin per elevator shaft to using an entire railway line between two cites to operate a single train clearly a waste of resources. By combining groundbreaking technology with a simple operation concept and convenience of passenger use, ThyssenKrupps Multi will transform the idea of a flexible number of cars per shaft from a distant vision for the future, into a reality.

To get this groundbreaking product onto the market our new test tower in Rottweil, Germany, provides the perfect test and certification environment. The tower is set to be completed at the end of 2016, and by this time, we aim to have a running prototype of Multi, Schierenbeck said.
