ELEVATOR WITHOUT CABLES REVOLUTIONIZES SKYSCRAPER PROJECTS

The era of the elevators that rely on cables ended 160 years after its invention. ThyssenKrupp has designed linear motors in cabins, making the transport of conventional elevators in multidirectional systems. MULTI technology improves lift capacity and efficiency, while reducing the energy footprint and peak loads in buildings.

The many booths that move in the same well vertically and horizontally will allow the buildings to have any height, shape and purpose. The first MULTI unit will be on testing until 2016.

Operation

Operating with the basic premise of a continuous circular system, Multi system uses linear motors technology and a unique circular movement (loop) which can include up to 16 booths (eight on each side).

With a target speed of 5 meters per second, the system will allow access to a walk-in elevator in every 15 to 30 seconds, with a stopover to transfer every 50 meters. The passenger waiting time will be reduced, with the dual input option on the ground floor, improving easy access in large buildings.

The Multi system also promises to offer a faster and more comfortable handling when compared to high speed elevators, which are limited by exerting pressure on the human body and generating discomfort when the lift speed exceed 10 feet per second.

Requirements

Even if the ideal height for the deployment of the system is of 300 to 600 meters, its use is not restricted to these patterns. Without relying on any kind of cables, with a multilevel braking system and inductive energy transfer from the elevator shaft to the cabin, the Multi requires axles with 6 square meters. This will translate into considerable cost savings for the construction industry.

Increased efficiency also would result in a smaller number of escalators and additional elevator wells, increasing up to 50%, the useful space of the buildings, and consequently the profitability of companies.



The tests will be made soon, in a tower in Rottweil, Germany, which is being built especially for that purpose. According to company officials, the Tower will be completed in 2016.
