Pulleys are versatile simple machines used across a wide variety of domestic, industrial, and architectural applications to make lifting and moving heavy loads easier. In residential settings, pulleys are commonly utilized in window blinds to raise and lower heavy shades, on clotheslines to slide wet laundry across yards, and in garage doors to assist heavy extension springs. In heavy industry and construction, multi-pulley crane systems and block-and-tackle rigs hoist massive steel beams, shipping containers, and masonry units effortlessly. In transportation, elevators rely on overhead drive sheaves and counterweights to balance passenger cabins smoothly, while automotive engines use serpentine belt pulleys to drive accessories.
