The original Hanseatic crane (Krantor) in Danzig (now Gdansk) was built in 1363. It was heavily damaged in WW II and rebuilt in the 1950s. This crane might have loaded and unloaded the ship they just found.
How did they power the crane, you ask? Human hamsters! Those guys must have been in great shape and eaten 10,000 calories every day they worked.

Great way to do it!
I was in Gdansk last month, it’s a great place to visit, highly recommend it.
I like the “five finger death punch” house.
