How Does a Pulley System Work? | Sciencing
A pulley system makes it easier to lift an object than lifting the dead weight by hand. A single pulley essentially changes the direction of the pull or force applied. When a person uses two or more pulleys in a system, then the system also multiplies the force applied besides changing its direction.

Conveyor Belt Pulleys Design Features
Pulley design considers shaft diameter, however, shaft design is based on the shaft alone without support from the pulley. Shafts can be subjected to three types of stresses, simple flexure or bending, simple torsion and combined as a combination of bending and torsion. Pulley shafts are subjected only to bending or combined loading.

Advantages and Disadvantages of Pulley Used
The pulley system does not store energy while performing the work. Movable pulley – Pulley drive can also design so that it moves along with the load. There are a number of types of rope and pulley systems (combined pulley system). Multiple wheels are used to lift heavy objects.-Types of belt drives-The materials used for belt drive

Pulleys are also assembled as part of belt and chain drives in order to transmit power from one rotating shaft to another. There are different types of pulley systems, Fixed or class 1 pulley has a fixed axle. That is, the axle is ""fixed"" or anchored in place. A fixed pulley is used to change the direction of the force on a rope (called a belt).
