Alter Krahnen

The stone harbor crane features two tread wheels, a double-arm mechanism, and a rotating cone roof for efficient cargo handling at the riverfront.

Built in 1413 to replace a pontoon crane, this structure lifted goods between one and two tons, supporting Trier's trade for nearly five centuries.

The crane represents medieval engineering skill and stands as evidence of the economic development along the Moselle River during the Middle Ages.

The structure remains operational despite changes to the riverbank, and visitors can examine its mechanisms through walking tours of Trier's harbor area.

Two massive human-powered tread wheels inside the crane enabled 360-degree rotation of the lifting mechanism for precise cargo placement.
