How Does it Work? - Escalator

The video explores the engineering behind escalators, focusing on their conveyance principle, mechanics, and safety features. It begins with an introduction to escalators and their purpose, followed by a detailed explanation of the conveyance principle, similar to conveyor belts. The mechanics section covers the steps, chain system, and motor, which powers the escalator. Safety features, such as sensors and synchronized handrails, are highlighted to ensure user safety. The video concludes with a discussion on the design elements that facilitate easy boarding and disembarking, emphasizing the engineering marvel of escalators.

What principle do escalators use to transport people between floors?

• Levitation

• Conveyance

• Magnetism

• Gravity

What is the main function of the motor in an escalator?

• To power the chain system

• To play music

• To synchronize the handrails

• To illuminate the steps

Why do the handrails move at the same speed as the steps?

• To reduce noise

• For safety and balance

• For aesthetic purposes

• To save energy

What happens if a sensor detects an issue with the escalator?

• The escalator speeds up

• An alarm sounds

• The escalator stops automatically

• The lights flash

How do escalators ensure easy boarding and disembarking?

• By having attendants assist

• By flattening out at the top and bottom

• By having wider steps

• By providing seating
