Conveyors are most regularly associated with large-scale production lines, where parts, devices, or vehicles are being assembled along the transportation line. They are also regularly used in commercial applications, especially retail. These mechanisms have earned their popularity due to their usefulness in production and transportation processes. Conveyors can transport objects that would be impossible or expensive to transport using manual power. They are considerably safer compared to any other means of transportation. They can adapt to different shapes and weight of objects, and they can be actuated by a variety of mechanisms, from manual power to electricity.
