How to Use a Barn Pulley to Make a Wall-Mount Light Fixture In the late 1800s, most were used to move hay from horse-drawn carts to lofts. To the American farmer, this mechanized system was the antidote to the back-breaking work of slinging hay with a pitchfork. By the 1950s, the hay elevator had pretty much replaced the barn pulley system.

Pulley â Simple machines â Physics You can use a pulley to make it easier to pull a rope, to change the direction of a force, or to get more mechanical advantage and lift something heavier than you can lift by yourself. With a fixed pulley, the pulley is attached to a hook or a wall and doesn't move, like the clothesline pulley in the picture here. A fixed pulley doesn't give you any mechanical advantage, but it changes the direction of the force.
