Super Double Deck Elevator System meets more flexible building needs than conventional double deck systems do, it can be installed in buildings with different floor heights.

Otis’ newly developed “Super Double Deck Elevator System” employs a pantograph as a movable car-connecting mechanism to accommodate floor height differences of up to 2 meters. On the top of the car frame that supports the two cars and the pantograph, two small motors are mounted. These motors with ball screws and helical gears coupled to them adjust the distance between the two cars to allow the cars to stop right at the respective floor levels.

The Super Double Deck elevator system frees architects of conventional double deck elevator system concepts to allow them to freely develop building plans just like ordinary single deck elevators.

As the distance between the upper and lower cars is adjusted while the elevator is running, no passenger in the cars can notice the cars distance adjusting operation.

Super Double Deck elevator system can provide customers with both increase in passenger traffic handling capacity and flexibility in building planning at the same time.

Otis’ Super Double-Deck elevator system has the following advantages:

  • The pantograph joint used on the system is designed to be positioned in the middle to support the upper and lower cars equally, enabling smooth, quiet and precisely controlled elevator operation with less power.

  • Otis’ advanced engineering technology provides maximum rigidity of the entire elevator system, allowing both upper and lower cars to travel up and down in stable condition.

  • The pantograph joint adjusts the positions of both cars to floors with different ceiling heights while the elevator is traveling and before the cars arrive at landings, avoiding operating efficiency penalty. As the pantograph joint works as such, passengers in the cars do not feel the pantograph joint is working.
