stability calculation for truck mounted cranes

[Guideon]

Hi everyone,

I was looking for a std to calculate stability of truck mounted crane. Recently I found an australian std "australian code of practice for crane installation on truck" (I think it is a part of 1418 au std), and I found it simple and practical.
But, when I tried to solve the example given at the std I realized that I missunderstand several things, I hope you can help me..
First, in appendix 5 (page 13):
-from the figure, the crane C.O.G coincides with the stabilizer line. Is it a particular case, or a design requirement when the boom is perpendicular to the tipping line?
-if not, how can I find the C.O.G of the crane when the boom is in it's max outreach? (I only found the C.O.G of crane - Fassi- in a stowed possition).
-why the crane rotation axis is a little bit shifted from the truck longitudinal axis (it is not on the truck axis).
Second, the equations under the figure (page 13), contain the F parameter (=3.45 m) to determine the tipping moment and the tipping load, but there is no F designated at the figure. I guess that this should be the distance between the tipping line and the S.W.L , but I am not sure, it could be also a virtual dimention..

Thanks, Guideon

Maybe it is in the near:

ISO: 4310, 15794, 22915-21

SANS/SABS: 15794, 10307

Hope this Help

Hi Determ

I have ISO 4310 but unfortunately it is not practical enough for the purpose I need. If you looked at the attached std you'll see the difference.
I do not have the other std you stated, and hence I do not know if it answers my questions. If you are familiar with these stds/ subject- I will appreciate your help.

Thanks, Guideon
