Pulley System and Mechanical Advantage 5:1 to 9:1 Progression

Written By: Lance Piatt

Building a progressive 5:1 to 9:1 MA system with the Rock Exotica Swivel pulleys, we have added a lot of functionality… quickly and efficiently. The industrial strength anchors are strong and easy to use. When building progressive mechanical advantages output is exchanged for input. 5:1 requires 5 feet of rope for 1 foot of gain. 9:1 requires 9 feet of rope for 1 foot of gain while adding the benefit of easier pull. Staggering the systems minimizes resets, simplifying the process.
