Abstract: Vertical City - Rope-less Elevators
Day 1 at 2:40
While more than half the world’s population already lives in urban areas, there is expected to be a 2.5 billion increase in urban population numbers by 2050. With severe restrictions on space, high-rise and super high-rise developments have proved to be the most economically and environmentally viable solutions to accommodate these rapidly growing urban populations.
As the nature of building construction evolves, it is imperative for the elevator industry to adapt its technologies to meet current efficiency demands– from the prevalent one-dimensional vertical arrangement to a two-dimensional vertical and horizontal arrangement, with more than one cabin operating in each shaft.
Typically, increasing the height of buildings demands consequently an increasing number of vertical transportation equipment – based on today’s common state of the art does this mean: more elevators with more vertical hoistway, which requests more and more space of the buildings footprint.
The presentation will give insight into a new innovative technology like Thyssenkrupp’s MULTI®, as a the first rope less elevator system would allow increasing transportation- and buildings efficiency by means of multiple car systems in reduced numbers of hoistway space.
By applying the linear motor technology to elevator cabins, the system enables passenger cabins to move in shafts in the same way that trains move in rail systems - with various numbers of cabins per shaft, and permitting vertical as well as horizontal movements inside buildings. Safety is ensured by the multi propulsion and redundant braking systems at the cabins and by the well-proven safety control system, developed by Thyssenkrupp Elevator for the TWIN elevator technology, which prevents cabins from getting too close to each other inside the shafts.
Operating without ropes, the new technology will abandon crucial limitations of travel height extension like weights of suspension means, rope sway effects and non-vertical building designs.
Super- and Mega- Highrise buildings are developed more and more to operate like cities in cities. Therefore, it’s no surprise that solutions for vertical traffic concepts in those buildings will develop more and more in a comparable way to the modern horizontal public traffic infrastructure concepts. The presentation will show feasible approaches to realize it by applying VT configurations with the MULTI system. The right combination of elevators system will be the key for efficient solutions.
Finally, the presentation will give a view on new approaches in technology to improve connections and network links to and between buildings and from buildings to public transportation systems like metros, etc.
The trend of growing cities with permanently increasing numbers of population needs new and visionary solutions for mobility in urban areas. People transportation in both dimensions vertically and horizontally has to enter new eras. No doubt, that’s a challenge for the all categories of transportation industry, for planners and architects as well as for all investors.
