Große Turmdrehkrane

[Holger1974 34]

Irgendwie war man vor 30 Jahren noch in der Lage, imposante Großkrane zu bauen, und heute nicht mehr. Zumindest was Deutschland angeht.
Hängt vielleicht auch damit zusammen, dass sich die Technik weiter entwickelt hatte oder kein Bedarf vorhanden ist / war. Ich wüßte nicht, dass in Deutschland schon mal ein 4000 HC von Liebherr im Einsatz war.

In 1981, Liebherr had also manufactured a tower crane with a free standing hook height 122m.
The crane was mounted on a 16x16m traveling chassis. It was a modified 450C with 750C tower sections.
The capacity was 50t and 15t@33m. The tower deformation was 3m backward w/o load and 3m forward when loaded. The operator had to take care of cabin delay (swinging) related to the chassis at travelling...
Crane was delivered in Saudi Arabia. Unfortunattely, I have no photos.

Ich habe ein Bild dieses Kranes, jedoch in einer Liebherr Veröffentlichung. Ich denke, das ich das aus Copyright Gründen nicht abfotografieren und hier einstellen kann.
Der Kran stand auf Schienen. Wenn der Unterwagen losfuhr, war er schon drei Meter losgefahren, ehe sich der Oberkran in Bewegung setzte.

@linaprim: great data! thanks for posting. This liebherr must have been very impressive. I'd like to know the dimension of tower square. I know that Liebherr 850C has a 3.86X3.86 tower for a 10x10 m base, 79m maxim HUH and 20 ton maxim load. But this tower sistem seems to me not suitable for that huge 122 m HUH

Greetings.

@Holger: you are right , the towers of the past were much more impressive than the ones from nowadays.
You say that there was one 4000HC in German or I am wrong?(I don't speak Germanv very well). I know that first Liebherr 4000HC was made in 2004 for South Korea. Have they manufactured another one before?

Greetings.

He meant that there is and was no 4000HC in germany. I think you are right about the crane for the Daewoo shipyard. They also got a 3150HC before.

The biggest Liebherr-crane working daily in germany I know of is a 1250HC(?) first used on a constructionsite at the main trainstation in cologne. Now working as crane for the handling of precast concrete segments in a factory.
