Moving PulleyĪ moving pulley, also known as a movable pulley, consists of wheels that are not attached to a particular surface, but instead, a rope or cable is attached to a stationary surface. Pulley can be made of wood, plastic, or metals, depending on the application. They are used in flagpoles, curtain binders, and wells. So instead of lifting a heavy object directly with upward force, a person can use a pulley to lift the object by pulling down on the rope. A fixed pulley minimizes the amount of force needed to move a load but allows a person to redirect the necessary force. Fixed PulleyĪ fixed pulley system consists of a wheel that is attached to a surface such as a wall or a floor and a rope that hangs free. There are three main types of pulley: #1. The drive element of a pulley system may be a cable, rope, belt, or chain. Pulleys may have a groove or grooves between the flanges around their circumference for running along the cable or belt. Pulleys are a simple machine composed of a wheel on an axle that supports the change of speed and direction of a taut cable or belt or the transfer of power between the axle and the cable.
