The primary function of a pulley is to change the direction of force. By redirecting the applied force through a system of ropes or belts, pulleys enable users to lift or move loads in different directions with minimal effort. This makes pulleys indispensable in various applications, from raising weights in construction to operating elevators in buildings.
