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
