Solution for high-rise

ith the continuing construction boom in India,
buildings are getting taller and owners are placing
Wgreater demands on their elevators to provide
increasing passenger transportation capacity. In this context, the
TWIN elevator system, a unique and revolutionary technology
from thyssenkrupp, can save time and space. It is the only elevator
system on the market that has two cars moving independently in
one shaft and addresses a range of issues that owners, operators
and occupants of tall buildings face daily.

Minimum Waiting and Travel Time
Because two cars operate independently in the same shaft, increase the traffic-handling capacity of existing elevator shafts
TWIN is able to take two passengers to two different floors by boosting the system’s capacity.
