Single Pulley
A single movable pulley is typically considered superior to a single fixed pulley because it reduces the amount of force needed to lift an object. The movable pulley changes the direction of the force applied, making it easier to lift heavy objects.
Single movable pulley
Single fixed pulley
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.

A single moveable pulley.
A single pulley system consists of one pulley that is attached to a fixed point. It is used to change the direction of a force, making it easier to lift or move objects. By reducing the amount of force required, a single pulley system can increase efficiency in lifting operations.

A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
