In the confineWorld’s First Ropeless Horizontal-Vertical Elevator System - continued
How Does It Work?
Thyssenkrupp MULTI applies the linear motor technology developed for the magnetic levitation train, Transrapid, to elevator cabins. Thereby enabling them to move in shafts in the same way that trains move in rail systems, with various cabins per shaft, and permitting vertical as well as horizontal movements inside buildings.
Safety is ensured by the multi propulsion and braking systems in the cabins, and the well-proven safety control system developed by thyssenkrupp for the TWIN elevator technology prevents cabins from getting too close to each other inside the shafts.
MULTI includes new elements such as new and lightweight carbon composite materials for cabins and doors, weighing a mere 50 kg instead of 300 kg in standard elevators, resulting in an overall 50% weight reduction as compared to standard technologies
Operating on the basic premise of a circular system, such as a paternoster, MULTI will use rope-less linear technology to operate elevators, and a single loop can incorporate various cabins.
- Conventional elevator: Traditional elevators in tall buildings require a large footprint and waste leasable space.
- Double-decker elevator: Move more people by stacking cars. But inevitably, extra power will have to move empty cars and passengers will experience phantom stops. And since the cars are fixed, the floor heights must be the same, limiting design options.
- TWIN, two cabins in one shaft: TWIN is more efficient because of independent operation of the cars, so that you can park cars if not in use. The flexible system works with different floor heights and it only stops on floors where passengers want to get in or out.
- MULTI: In addition to the many advantages offered by TWIN, thyssenkrupp have included a rope-less linear motor and the ability to travel horizontally. This allows MULTI to be used as a shuttle, optimizing traffic. Greater handling capacity and additional flexibility can be achieved by also incorporating a double entrance lobby.
