Modular Suspended Platform Double Deck
DD elevators comprise two passenger cars, one located above the other, connected to one suspension and drive system . The lower and upper decks can serve two adjacent floors simultaneously and during peak periods the decks are arranged to serve `even' and `odd' floors.
Otis Elevator Company pioneered an invention using two cars contained within a common sling and, in 1931, installed eight 'double-decker' elevators with attendant operation in New York City's 66 storey 'Cities Service Building' .
Furthermore, visual representations like the one above help us fully grasp the concept of Double Story Building Double-Decker Suspension System.
It is a lifting system for people and loads, mainly made of aluminum, used to carry out specific vertical installation, inspection, and maintenance work in suspension , such as facades, bridges, chimneys, silos, and tanks, awnings, or patios.
