English: A headframe (also known as a gallows frame, winding tower, pit frame, shafthead frame, or headgear) is the structural frame above an underground mine shaft. Modern headframes are built out of steel, concrete or a combination of both. Timber headframes are no longer used in industrialized countries, but are still used in developing nations. Traditionally steel headframes are used when a drum hoist is employed, and concrete headframes are built for friction hoists, however a steel headframe can be used with a friction hoist for shafts with a smaller capacity and depth.
