How to Get a Pulley to Spin Faster

Detach all objects from the pulley system and remove the rope.

Hang a new pulley next to or beneath the old pulley. The location doesn't matter so long as they sit close enough to slide rope through both.

Measure the length of the old rope with a tape measure. Next, cut a piece of rope twice as long as the old rope. You need additional rope to work with since you have an additional pulley in the pulley system.

Wrap the rope around both pulleys. If the two pulleys sit in a vertical arrangement, begin wrapping the lower pulley first. Then, bring the rope upward and wrap the rope around the top pulley one time and bring the rope over to the side you want to pull. For pulleys arranged horizontally, begin wrapping the pulley that sits opposite the side you want to lift. In both situations, leave enough slack on both ends to attach the object and to pull.

Attach the object you need to lift, and pull down on the rope using roughly the same force you used when lifting with only one pulley. Since the additional pulley reduces the necessary lifting force by half, both pulleys spin faster. You have to pull for a longer duration, though, because of the laws of energy conservation. The distance required to lift the object doubles, because the force has been halved.
