Terex had planned to have the crane ready to ship to Ainscough in the first half of 2010. However, when it came to final strain-gauge testing of this huge innovative machine, results showed it required strengthening in certain sections. The testing process inevitably requires several iterations but is now just about complete, Terex says.
Terex engineers say that there is nothing unusual about such delays with new projects, especially ones as ground-breaking as this. Although Liebherr already has a 1,000t telescopic crane with a 100m boom, the Terex rival differs significantly in that it will be able to travel with its boom installed and has a footprint the same size as the old 650t-class AC 650.
The footprint means that any refineries or plants that have prepared ground for the AC 650 to set up will have no work to do to bring the AC 1000 on site.
