Passenger Elevator
An examination of historical architecture reveals that while tall buildings could be constructed in the past,
the prevalence of numerous stairs likely deterred their widespread development.
This issue persisted until 1854 when Elisha Graves Otis, an American mechanic, invented a safety brake (parachute) that halted the elevator shortly after a rope break, significantly enhancing elevator safety.
This invention paved the way for the widespread use of elevators for vertical passenger transportation.
Today, passenger elevators, operating at speeds between 1 to 2.5 meters per second, are installed in medium-traffic buildings typically no taller than 30 meters.
Choosing the right capacity and number of elevators is crucial in building design, as any mistake can result in reduced passenger satisfaction, longer waiting times, or reduced usable space, leading to economic losses.
