A chain pulley block, or manual chain hoist, is a lifting device used to lift and lower heavy loads (from 0.5 to 30+ tons) via a hand-operated, gear-driven chain mechanism. It provides a high mechanical advantage, allowing a single operator to lift heavy materials securely in factories, construction sites, and
