Leonardo da Vinci designed a crane with a rotating arm for lifting construction materials.
Leonardo’s crane studies explored how builders could raise and position heavy loads more efficiently. His drawings include lifting machines with booms, ropes, pulleys, and mechanisms for turning or controlling the load. A rotating crane arm could extend the machine’s working area without requiring the entire base to move.
These designs belonged to Leonardo’s broader investigations into construction technology, mechanical advantage, and controlled motion. Cranes were already known before Leonardo, but Renaissance engineers developed new arrangements that improved lifting, reach, and portability.
A crane is not identical to a hoist or a derrick. A hoist is primarily the lifting mechanism, while a crane combines lifting with a supporting structure that can move a load horizontally or rotate it. Leonardo’s drawings often combine several mechanisms, so the general term crane is the clearest canonical identification.
