What is pulley Kit ?

The pulley is one of the six simple machines. Basically, all that a pulley is is a wheel spinning around an axle to aid the motion of a belt. The sprockets on a bike, for example, are a type of pulley, because when they spin, they drive other sprockets on the bike, that in turn rotate the rear wheel.
