Tower tractor crane at the inland harbour of Trier from 1413.In contrast to modern cranes, medieval tractor cranes and hoists - much like their counterparts in Greece and Rome[20] - were primarily capable of a vertical lift, and not used to move loads for a considerable distance horizontally as well.[17] Accordingly, lifting work was organized at the workplace in a different way than today.
