Capstan brake

A capstan brake is a mechanical device used to control the movement of a cable or rope, often found on ships or in industrial settings. It employs a rotating drum (the capstan) around which the rope is wound. When force is applied to the rope, the capstan brake tightens, creating friction that slows down or stops the movement. This ensures safe operation when lifting, lowering, or holding heavy loads. Its design allows for precise control over tension, making it essential for tasks like anchoring ships or hoisting equipment.
