Richier GT1174. Not realy a giant tower crane, but in one of its versions it can attain a height under hook of 83 meters, freestanding, a significant height for a Richier.

@S46: very good job!

We have here from you almost all Kroll range- k800, k1000, k1400, k1600, k1800, k2500, k10000 and of course the mighty k25000, a real masterpiece!

Would also be nice a drawing of the giant kroll k3000 of late70s, erected on rails to its maximum height of 150m, under hook. According to Kroll officials the crane can be erected to its maximum possible height of 150 m, on rails, too, with a rail gauge of 16m and 250 tonnes concrete balast.

My dear friend !

The drawings of K3000 are finished, the K 4000 ( ? Could someone verify ? ) is ready also, currently I am finishing the K 5000, in 3 versions.
Then I have completed my work on Kroll`s big ones.

If you could tell me the jib - length of the K3000, when erected to 150m, and the possible
tower - system which will be used then ( I don`t think standard will do here ), an according drawing will not impose much problems for me, I think.
At least I assume, that the jib lenght then will not be over 100m... which seems to be otherwise possible, on that giant machine...

Can't wait to see all these Kroll towers! It sounds realy great!
The jib lenght (or, to be more accurate the range, because the jib is with a few meters longer ) for 1978-1980 crane was 78 meters. I don,t know if for complete height of 150 meteres was still available that jib span, but kroll officials havn,t specified something about any decrease of that lenght. I also know that rail version would imply a 16 meters gauge base,if used 250 tonnes concrete balast. The tower system is the same as the one used for the crane delivered in USA in 1980. It is specified that it can attain 150 meters under hook on the same mast configuration. Anyway that mast it's huge. I measured with autocad and it returned to me a value of 8.3X8.3 meters. That is as much as kroll k-10000!
Also a comparisson with other giant cranes would be of maximum interest!

Got it.
Actually, I assume it to be the towersystem of K 10000 also,
and I think we have worked on the same datasheet here...
If that specific crane does really exist, ( 1980 / USA as you mentioned ) I wonder where and why ?
Any picture of that giant available ?
Because I thought it would be only a principle sketch for a K 3000 from Kroll.

Anyway, I`ll do my best.
I just have to figure out the 16m portal / base...portal would be more interesting,
what do you think ?
