TWIN two elevators in one hoistway

The idea of having two independent elevators in the same shaft dates back in the 1930s, but it took modern-day technology to turn it into the reality. To make this system work and achieve intelligent control ThyssenKrupp needed to use advanced destination dispatch system.
ThyssenKrupp is comparing the efficiency of TWIN technology to four shaft elevator group. In case you decide to use TWIN you will have one shaft less – two TWIN systems and one regular single elevator system. This means more floor space, but in case one TWIN system goes down, it means more inconvenience.

The two TWIN cabs are prevented from getting too close by a quadruple redundant safety system: intelligent allocation of calls; automatic monitoring of minimum safety distances; emergency stop function if the safety distance is breached; and automatic engagement of the safety device in the extremely unlikely event that the first three stages fail. The TWIN system has been fully certified for safety by the German TÜV inspectorate.
In my opinion, the system would be very efficient in office buildings where companies reside on multiple floors and travel between a few floors is required.

Elevator Motor That Helped Save Thousands

A 10,000-pound elevator motor that shuttled hundreds of people a day at the original World Trade Center will be part of the National Museum's permanent exhibit.

The exhibit will also tell the story of John Menville, who arrived at the World Trade Center in 1969 to install the elevators, on 9/11, thousands of people, including Menville, used the elevators to evacuate. When the first plane hit, Menville's immediate thought was of how long it would take to repair the elevators.

When Menville, now 65, helped install the massive 8-foot-by-5-foot motors, called 339 machines, they were the first in North America and the biggest in the world. The only place they had ever been used before was in South African diamond mines.

After installing the elevators, Menville and his coworkers from Otis Elevator Company got to test-ride them, flying through the building at 1,600 feet per minute.

The elevator motor will sit at bedrock in the museum, in a vast corridor dotted with other large objects, like twisted steel and crushed emergency vehicles. Visitors will pass through the gallery on their way to the primary exhibit, where they will see the story of 9/11 told through the eyes of the individuals who experienced it.
