THE 6:1 PULLEY SYSTEM

As we continue to apply more pulleys to the system then the mechanical advantage ratio increases. In this system some of the pulleys that have been used are double pulleys.

A double pulley has two pulley wheels usually of the same diameter housed inside a single block, the two pulley wheels are able to move independently of each other. By using a double or multiple pulley block we are able to condense the pulley system making it more manageable.
