A headframe (gallows frame, winding tower, hoist frame, pit frame, shafthead frame, headgear, headstock, poppethead) is a tall timber, steel or concrete structure above an underground mine shaft. Headframes are built to safely handle loads from mine hoisting systems and to facilitate easy movement of rock, equipment, people and materials into and out of the mine shaft. Headframes are an iconic feature of active and former mining landscapes worldwide, often becoming symbols of their mines and communities built around them.
