Five stories usually has an Panoramic Elevator
Any building in most large cities taller than, say, five stories usually has an Panoramic Elevator, and often, new buildings of even three stories have one. If you live in a large city, chances are that you use an elevator every day.
Chances also are that you don’t give much thought to it, and when you look at the inspection report posted inside the elevator cab, you don’t spend much time analyzing it. Yet, elevators are essential to any mid-rise or high-rise building. See how upset people are when their elevator is out of service for even a few hours!
There have been elevator-like hoist devices throughout history, but in 1853, American inventor Elisha Otis invented a freight elevator equipped with a safety device to prevent the elevator from falling in case a cable broke. This increased the use of elevators. Other improvements followed, such as telephone communications between the operator and an “elevator supervisor” and signal-controlled elevators.Three Items Required In An Elevator Lobby - Desenk Elevator.
