A nifty little mover
Looking like something out of Willy Wonka’s chocolate factory, this image from ThyssenKrupp’s testing tower shows the world’s first ‘ropeless’ elevator. Thanks to its cable-free design, the MULTI elevator can move both vertically and horizontally, with exchanger mechanisms controlling direction, much like points on a railway line.
Very tall buildings require multiple lift shafts, as having a single, central shaft can undermine their structural integrity. But as Markus Jetter, ThyssenKrupp’s head of project development, explains: “With MULTI lifts, architects are no longer restricted in their designs by concerns about elevator shaft height and vertical alignment. Traditional shafts can occupy 40 per cent of the floor space in a typical tall building; MULTI halves that, leaving more room for offices and apartments.”
The first MULTI elevator is due to be installed in the new East Side Tower in Berlin in 2020.
