Pulley:- Step Pulley
A Step Pulley is a system of pulleys made up of many different sizes. The typical step pulley consists of a two- to four-pulley configuration. This type of step pulley is found on equipment such as a drill press where different operational speeds can be produced simply by changing the belt to a different pulley size. The step pulley is always operated in pairs, and when the belt is changed on one pulley, it is also changed on the corresponding pulley on the other side of the belt.
