Capstan bars

Capstan bars are sturdy metal rods used in maritime and industrial settings to manually turn or control capstans—large rotating devices that hoist heavy loads like anchors, sails, or cargo. By inserting the bars into designated holes on the capstan, workers can leverage their strength to rotate the mechanism, transferring force efficiently to move or lift substantial weights. They are essential for providing mechanical advantage, making it easier to handle heavy, cumbersome tasks on ships or industrial sites without complex machinery.
