TWIN®
Two cars. One shaft. One quantum leap.
The revolutionary system in elevator design.
 ThyssenKrupp Elevator is the first elevator manufacturer implementing the idea of two cars travelling independently an a single shaft.
Ideal for building heights between 50 and 200 meters, TWIN® also provides entirely new solutions for building design and layout of elevator groups.
This makes completely new traffic concepts in buildings possible. Same handling capacity with 25 % less shaft.
Functional Description
Both elevators are equipped with their own traction drive and travel above one another on the same rails. The intelligent ThyssenKrupp destination selection control DSC is the central and indispensable component of the TWIN® and provides perfect coordination of the elevator group.
The passenge target landing is recorded in addition to the travel direction during the call prior to entering the car, which prompts the control to assign the most suitable elevator to the call location. 
Safety Concept of the TWIN®
A 4-level safety concept assures that the cars maintain a minimal clearance from each other during any operation condition. The safety concept of the TWIN® passed all cpmprehensive tests as part of internal development procedures, as well as the TüV test, thus having impressively demonstrated a safety standard that meets even the highest demands.

Safety level 1 |
|
Target calls are always distributed so that the cars will not hinder each other and always maintain a minimal clearance. |
![]() |
Safety level 2 |
|
Monitoring of minimum clearances. When the cars approach each other, the speed is reduced so that an operational stop is possible at any time without exceeding the minimum clearance. |
![]() |
Safety level 3 |
|
Emergency stop. When another safety clearance is exceeded, the drive are stopped and the operating brakes activated. |
![]() |
Safety level 4 |
|
 If the absolutely unlikely event occurs where none of the three safety levels lead to slowing down the cars, the safety gears on both cars are activated by force.
