If we assume a large building with multiple elevators, what would be the name of a group of elevators?
Consider a group all those in close vicinity to each other, in the same hall but not necessary with the same amount of locations (stories). If a wide building is considered, it's perfectly possible to have for example 2 elevators at the North side and 2 elevators at the South side of the building. North and South would be considered their own group (if the distance between them is large enough).
We're walking towards the Northern group of elevators.
Two out of three elevators from the Southern group of elevators broke down.
