Noun. 1. pulley-a simple machine consisting of a wheel with a groove in which a rope can run to change the direction or point of application of a force applied to the rope. pulley block, pulley-block, block. block and tackle-pulley blocks with associated rope or cable.
In a pulley system, one end of the rope is attached to the load and the other end is pulled in order to move or lift the load. A single pulley has only one wheel. The pulley makes the task of lifting a load more convenient since it is easier to pull a rope down than it is to lift a weight up.
