From ECD40.
For those of you that were with me discussing the high lift overhead crane problem that would not fit through the lifting wells in the high rise structure, it is now resolved.
We turned the drum through 90 degrees and increased the drum diameter, still maintaining the single layer of rope. This enabled the crane to remain within the CMAA designation. We did not have to resort to the Lebus shell solution.
So technically, we have solved the problem, but we are still at it with the supplier over the contractual issues. At least we will now have a crane that will be 'fit for purpose'.
Thanks to all of those who gave their comments along the way. For those of you that may get involved in the future with a high lift crane operating inside of a building with access wells - watch out for the rope fleet angles.
