This photo : a medieval tread wheel crane from 1288, rebuilt in 1434, in service until 1767; modern reconstruction of the medieval crane at the port of Bruges with two tread wheels. A tread wheel crane (Latin magna rota) is a wooden, human powered, hoisting and lowering device. It was primarily used during Roman times and the Middle Ages in the building of castles and cathedrals. The often heavy charge is lifted as the individual inside the tread wheel crane walks. The rope attached to a pulley is turned onto a spindle by the rotation of the wheel thus allowing the device to hoist or lower the affixed pallet.
