Große Turmdrehkrane

After studying the complexity of the job and the very minimal space they had to work with, Syncrude concluded that a tower crane was the best option for the majority of their lifts, and so the Kroll 10,000 was brought in. Only 15 of these massive machines were ever built, mostly for the nuclear power industry, but the constructability team found one available in Denmark, and Syncrude purchased it to help with the construction of the project. Tower cranes such as this are normally used to construct skyscrapers in areas where there is very limited working space.

This type operates very much like a crane tower, in that it hoists and sets loads, but in the Kroll 10,000?s case, the operator sits 320 feet above the ground. The foundation of the tower itself will be octagonal in shape, and measure about 50 feet wide. While most lifts for the Emission Reduction Project will be in the 90 to 100 ton range, the Kroll 10,000 will stick out like a sore thumb - a very innovative and capable sore thumb.

At a radius of 330 feet, the Kroll has a lifting capacity of 104 tons and a hook height of 300 feet. At a 150-foot radius, the lifting capacity more than doubles, to 240 tons. You can bet that with such heavy-duty machinery involved, Kroll technicians will properly train all selected crane operators. With its outstanding lifting capacity, along with the various radii, the tower crane will allow for more pre-assembly to be done off site, thereby avoiding an overcrowded working environment.

Ernie Sheaves, a crane and rigging specialist and also a member of the constructability team who recommended the Kroll 10,000, said that Syncrude ?will be able to perform more than 90 per cent of their heavy lifts for the project with this tower crane without having to relocate.? He also notes that about two-thirds of the Emission Reduction Project construction site would have been covered by crane mats just to get things up and running.

?We?re eliminating the need to build massive crane pads each time we want to move a crawler crane.? The less time it takes to start reducing emissions, the better. Construction for the Kroll 10,000 is expected to be complete by the middle of September 2007 and ready for use by October.

Hi,

At this moment the Dutch Potain dealer is erecting 2 MD 1100 with in the city limits of Rotterdam.
They are now several weeks on the way and so far are still working on the assembly of the tower sections.

Do you have more pictures of the 800 HC crane and undercarrige and were does this one stand?
I know in the South of Italy there was one,but this one has been dimanteled and sold some were in to Asia or Sout America several years ago.

Greetings

I posted some time ago a pdf document from Rodson about Liebherr 800HC. I don,t know where that crane is located, unfortunately.
One 800HC is offered for selling on th net.
