An elevator or lift is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack.

In elevator is essentially a platform that is either pulled or pushed up by a mechanical means. A modern-day elevator consists of a cab (also called a “cabin”, “cage”, “carriage” or “car”) mounted on a platform within an enclosed space called a shaft or sometimes a “hoistway”. Come learn how a traction elevator work! We’ll also explore history and different types of elevators.
Watch the video from Jared Owen for more info.In a “traction” elevator, cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced by a counterweight.
