What it is Filled
The structure above a mine shaft that carries the sheave wheels over which hoisting ropes pass to raise and lower cages, skips and equipment, also called a headgear, pithead frame or winding tower, built in timber, steel or concrete in forms from lattice frames to the massive Malakoff towers of German and Belgian coalfields that supported the sheaves while winding engines were generally housed separately; headframes are the visual emblem of mining and many survive as industrial heritage.
Why it exists Filled
Let an agent explain headframes and their function and forms, relay engineering and heritage aspects, identify notable examples, and distinguish headframes from other mine structures.
Distinguishing features Filled
- Sheave wheels
- Shaft position
- Timber, steel or concrete
- Heritage symbol
What robots and AI may and may not do Filled
Must not
- Operate hoisting equipment without the mine operator's authority and safety systems in place.
- Disable overwind, brake or signalling protections on a shaft.
- Approve continued use of a headframe with structural defects.
- Guide visitors to climb or enter abandoned headframes or open shafts.
Only with a human decision
- Allowing people to be raised or lowered after an inspection finding.
- Demolishing a headframe of heritage value.
May
- Monitor hoisting ropes, sheaves and structural condition of a headframe for its operator.
- Document historic headframes for heritage records.
Moral aspects Filled
- Hoisting failures can kill miners in the cage or shaft.
- Headframes are landmarks of mining communities and their history.
Who is affected
- Mine workers
- Former mining communities
- Trespassers
Owners Filled
Steward
The mine operator; a heritage body where it is protected.
