Elevator systems are mechanical devices used to transport people and goods vertically between different floors of a building. They consist of a car that moves up and down a shaft, powered by a motor. Elevators can be found in various settings, including residential buildings, commercial spaces, and industrial facilities, making them essential for accessibility and convenience. There are different types of elevator systems, such as hydraulic, traction, and pneumatic elevators. Hydraulic elevators use fluid pressure to lift the car, while traction elevators rely on cables and pulleys. Pneumatic elevators use air pressure to move the car, offering a unique design and operation method.
