A lift, also known as an elevator, is a machine that moves people or goods between different floors of a building. It usually consists of a cabin that travels up and down a shaft, making it easier for people to access higher levels without using stairs. Lifts are especially helpful in tall buildings, where climbing stairs can be tiring or impractical. Lifts operate using a system of pulleys and cables, or sometimes hydraulic systems. They are controlled by buttons inside the cabin and on each floor, allowing users to choose their destination. Safety features, like emergency brakes and alarms, ensure that lifts operate securely, making them a vital part of modern architecture and urban life.
