Primitive Treadwheel crane used for building construction in Medieval times such as for Reims cathedral, France 119120_Reims

---

A treadwheel crane (magna rola) 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 treadwheel 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.
