• A pulley is a mechanical device which contains a wheel and rope/belt/chain to lift the heavy objects. The wheel of the pulley is generally fixed to a hinge and rotates on an axle or shaft. In a simple arrangement of the pulley, chain/rope/belt/cable is the driving element that drives over the wheel. At the one end of the rope, the object is loaded, and from the end, when the rope is pulled down the object lifts. To lift large objects an assembly of pulleys are used. These are also used to transfer power from one rotating shaft to another. The advantage of the use of pulleys is that by applying a little force heavy objects can be lifted. In other words, the pulleys multiply the force to lift the heavyweights which cannot be lifted with bare hands.
