Elevators can feel like magic. Step inside. Select your floor. Poof! The elevator quickly takes you where you want to go.
But an elevator doesn’t run on magic. It’s a machine. And it’s made up of several smaller machines. These machines work together to make the elevator move. An electric motor powers the elevator. A pulley system hoists the car up and down through an elevator shaft. The controller is the “brains” of the elevator. When you push a button, the controller tells the car which floor to go to.
The Sky’s the Limit
Elevators are an important part of the modern world. “They make taller buildings possible,” Dot Mynahan told TIME for Kids. She works for the Otis Elevator Company. “Elevators are also important for handicapped people,” Mynahan says. “They make buildings more accessible to everyone.”
The first passenger elevator was installed in 1857, in New York City. Since then, technology has improved. Elevators have become more energy- efficient. They are also much faster. Have you heard of the Empire State Building, in New York City? Its elevators whisk visitors from the ground floor to the 86th floor in less than a minute.
What’s next for elevators? “The possibilities are endless,” Mynahan says.
A Historic Moment
Elisha Graves Otis was an inventor. He created the world’s first safety elevator. In 1854, he gave a daring demonstration of how it worked. Crowds gathered at the World’s Fair, in New York. Otis rode his elevator high into the air. A man cut the rope that was lifting it. The crowd gasped. The elevator should have fallen, but it stayed in place. “All safe, ladies and gentlemen,” Otis said, “all safe.”
