Kan mij iemand zeggen hoeveel liftkokers per toren (Twin towers) er waren?

Elevators were the primary mode of routine ingress and egress from the towers for tens of thousands of people daily. In order to minimize the total floor space needed for elevators, each tower was divided vertically into three zones by skylobbies, which served to distribute passengers among express and local elevators. In this way, the local elevators within a zone were placed on top of one another within a common shaft. Local elevators serving the lower portion of a zone were terminated to return to the space occupied by those shafts to leasable tenant space. People transferred from express elevators to local elevators at the skylobbies which were located on the 44th and 78th floors in both towers. Each tower had 99 passenger and 7 freight elevators, all located within the core of the building.
