pulleys
Rope-guided lifters
Pulleys is the plural of pulley, a wheel with a grooved rim through which a rope or chain runs, used to lift heavy loads or change the direction of force.
Simple machines like pulleys reduce the effort needed to raise objects: The stage crew used pulleys to raise the curtain.
A system of multiple pulleys working together is called a block and tackle.
