Lifters, commonly known as elevators, are mechanical devices used to transport people and goods vertically between different floors of a building. They operate using a system of pulleys, cables, and motors, allowing for efficient movement in high-rise structures. Elevators can be found in various settings, including residential buildings, commercial spaces, and hospitals. Modern elevators come in different types, such as hydraulic and traction elevators, each designed for specific building requirements. Safety features, like emergency brakes and alarms, ensure passenger protection during operation. Elevators have become essential in urban architecture, enhancing accessibility for individuals with mobility challenges and improving overall building functionality.
