A pulley system is made up of a pulley and a rope. A pulley is, in essence, a wheel with a groove going all the way around it so that a rope or a cable can fit in it securely.
One could also run an indented track around a wheel.

The type of pulley used to pull a bucket out of a water well is typically referred to as a "well pulley" or a "well bucket pulley." This type of pulley is specifically designed for lifting objects out of wells and is often made of durable materials such as steel or iron to withstand the weight of the bucket and its contents. Well pulleys are commonly attached to a rope or chain system to facilitate the lifting process efficiently.
A typical pulley system consists of several key materials: the pulley wheel, which is often made of metal or durable plastic for strength and smooth rotation; the rope or cable, typically made from synthetic fibers, steel wire, or natural materials like hemp; and the mounts or brackets, usually constructed from metal or reinforced plastic for stability. Additionally, bearings may be included to reduce friction and enhance the system's efficiency. Together, these components allow the pulley system to lift and move loads effectively.
