Have you ever stepped into an elevator, pushed a button, and wondered what makes it move?
Elevators may seem simple from the outside, but hidden behind the doors is an incredible system of motors, cables, wheels, counterweights, computers, sensors, and safety equipment working together.
How Does an Elevator Work? takes curious young readers inside the elevator shaft to discover exactly what happens after they push the button.
Kids will learn how a powerful electric motor turns a grooved wheel called a sheave, strong ropes or belts support the elevator car, and a counterweight moves in the opposite direction to help balance the load. They'll also discover how guide rails keep the car on its path and how a controller knows where the elevator should stop.
But how does an elevator stay safe? Young readers will explore locked doors, sensors, speed governors, safety brakes, buffers, alarms, and other systems designed to protect passengers.
They'll even meet the inspectors, technicians, firefighters, and building crews who test, maintain, and prepare elevators for emergencies.
Packed with colorful illustrations and easy-to-understand explanations, How Does an Elevator Work? reveals the fascinating machinery hiding behind something millions of people use every day.
Perfect for curious kids who love machines, buildings, engineering, technology, and discovering how the world works!
Part of the How the World Works series-educational books that reveal the amazing people, machines, and systems behind the world we see every day.
