Climbing Toward the World’s First Rope-less Elevator System
Almost one year ago, elevator manufacturer ThyssenKrupp announced its plans to develop the world’s first rope-free elevator, MULTI, which promised to convey building occupants not only vertically, but horizontally, as well. Now, it boasts the first fully functional model, and it’s working and moving as planned.
Unveiled yesterday at the ThyssenKrupp Innovation Center in Spain, the 1:3-scale model features a pair of 32-foot-high shafts shared by four cabs to demonstrate linear motor technology, which is based on magnetic levitation (Maglev) trains.
A Refresher on MULTI
MULTI proposes a circuitous system by using 90-degree turning guiding equipment and the linear motor technology. This combination will move more cars per shaft — vertically and horizontally — ultimately reducing waiting time for an elevator to an estimated 15 to 30 seconds maximum. To ensure safety, multi-propulsion and braking systems in the cabins will be employed, as will the manufacturer’s TWIN elevator safety control system that already has a proven record.
The MULTI system will also offer both real estate and sustainability benefits. First, it can increase passenger capacity while reducing the elevator’s overall footprint in a building by half — only by removing the ropes and equipping the linear motors. Second, cabins and doors will be made with new and lightweight carbon-composite materials that will reduce weight compared to standard lifts by 50 percent.
Production of a full-scale prototype is currently underway and will be used in a test tower in Rottweil, Germany. Construction of this tower is slated to be completed by the end of 2016.
