The crane for lifting heavy loads was invented by the ancient Greeks in the late 6th century BC

They were used by the Greeks and Romans in the BC years.

Probably Egyptians or similar, swinging big stones around on the end on long bits of wood, levered up at the other end.

No winching or lower ability, just brute force and leverage, but they still could lift and move things.

The ancient Egyptians knew about reeving of ropes so I think the may have been the first.
