A movable pulley is a pulley where when you transfer a weighty object, the drum moves with it. There is no modify in the direction of the pressure you want to apply, but the load will “come to feel” lighter than it really is. For example, if you might be hauling a heavy hay bale up the barn’s attic, a moveable pulley will make the load feel a lot lighter, even however you are pulling in the identical route.
