Agreed.
I also think, that the K 3000 represents the most ingenious and versatile machine from Kroll.
The bigger ones are more radically optimised machines for heavy lifting.

On to Potain then ? That is, due to obvious reasons, very difficult.
Let`s see.

@Kim: unfortunately I don't have any detailed data sheet for Potain MD1100, so I can,t help you. the only data I knoe is the one from Potain site

Peiner first ? or Potain ? or better Peiner... ? Well, I don`t know. Peiner`s datas are more comprehensive...
But both are on their way, it may take some more time, to be halfway correct in result.
( I`m struggling with Potain`s MD... telescoping system at the moment. Son of a b.... )
F.ex.: How does the climbing section crossframe get extended to securely mount with the maintower chords adaptor ?
( I mean the lower two pins of the assembly`s 4 pin adaptor ) Is this done manually ? Can`t be, but I see no mechanism there !
F.ex:. Why is the lifting mechanism tilted, so it can lift only about 2m at a full cycle of the hydraulic cylinder ?
Even why then there is an insertion hole approx every 50cm ? Emergency Exit ?
There has to be much ( unneccessary ? ) precision behind that.

All things by Potain, that I`ve got no clue by now.

Manually, see the photo (from internet)

It works on a lever principle. In this way hydraulic cylinder`s capacity is increased 2x.

Even why then there is an insertion hole approx every 50cm ? Emergency Exit ?
There has to be much ( unneccessary ? ) precision behind that.

In these holes is attached upper part of the tower when telescoping. Cylinder extends 1m, holes every 0,5m...
