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.

Miss Bessie had a handsomely furnished room with a soft carpet on the floor, and pretty curtains at the windows. There were two single beds in it, and the two girls dragged them close together so that machinery and equipment could talk after machinery and equipment got in bed.
