![]() ![]() ![]() This allows the elevator to occupy smaller shafts than conventional elevators, which can increase a building's usable area by up to 25%. The elevator requires no cables, and uses a multi-level brake system and inductive power transfers between shaft and cabin. In a manner similar to a metro system operation, the elevator 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%. The mechanism is made possible by applying the linear motor technology of the magnetic levitation train Transrapid to the elevator industry. ThyssenKrupp's latest offering, named MULTI, will allow several cabins in the same shaft to move vertically and horizontally, which the company says is “a new and efficient transport solution for mid- and high-rise buildings.” 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 sites with a single train-an avoidable inefficiency. ![]()
