Ever wondered how Trier managed its bustling river trade centuries ago? The answer lies before you in the Alter Moselkran. This old crane stands as a testament to Trier’s rich history. It is a significant landmark along the Moselle River.
The Alter Moselkran dates back to 1413. It highlights Trier’s importance as a trading center. The crane is on the right bank of the Moselle at Krahnenufer.
This harbor crane is a remarkable feat of medieval engineering. The stone structure was designed to lift one to two tons of cargo. It supported Trier’s busy riverfront trade. The Alter Moselkran features two massive tread wheels. It also has a double-arm. A 360-degree rotating cone roof allows efficient cargo handling. All this was propelled by human muscle power. Winch men operated the drive of the two huge wooden wheels. Each wheel has a diameter of 4.16 meters.
The Alter Moselkran replaced a less stable pontoon crane. It was essential for economic and industrial growth in Trier. This was especially true during the Middle Ages. Land-based cranes enabled consistent loading and unloading. This did not depend on the river’s fluctuating water levels. For nearly five centuries, the crane helped load and monitor taxable goods. These goods entered and left the city. The crane allowed seamless monitoring. It showed which taxable goods were transported in and out.
In the 18th century, the Alter Moselkran underwent renovations. It gained a second cantilever arm. This improved its functionality. In 1778 a second boom was added as a balance element. The total width of both booms is about 26 meters today. The booms are 15 meters above the ground.
The Alter Moselkran inspired the design of the Zollkran. This customs crane was installed about 250 meters upstream. It relieved the load on its predecessor. The newer harbor crane was in operation until 1910. The oak gear of the Kranhaus was dendrochronologically dated to 1778 and 1863.
Although the Alter Moselkran remains fully operational, changes to the riverbank have left it too far from the water. It can no longer serve its original purpose. However, it continues to be a landmark of Trier’s economic heritage. It is one of the oldest preserved cranes in the former German-speaking territories. The Alter Moselkran is a cultural historical industrial and economic landmark of Trier.
Interestingly, the Alter Moselkran served as a model for the Zollkrahnen. Though you cannot go inside the cranes, they are worth a visit. Combine your visit with a walk or bike ride along the Moselle. The crane is fully functional today. However, it is no longer close enough to the water since the Moselle was banked up. The Alter Moselkran stands as a proud symbol. It is a reminder of Trier’s enduring legacy.
