Crane Lift - Rectangular Tank
Crane Lift - Rectangular Tank
(OP)
Hey Gang,
I posted a while back about rectangular tank design and found some very good resources. Thanks to everyone that helps. I can provide some research papers for anyone interested.
Anyway, now I'm analyzing the tank for a crane lift. The tank will have four lifting eyes and I want to do a check to see how it will perform when lifted full of water (probably a very conservative scenario) Anyway there is not alot of information out there. I have checked the lifting eyes and welds for tension, bending and shear failure. There are three 'W' beams across the bottom that I will check for sag/deflection when lifted.
Beyond that I'm not sure what to check, is there anyhthing I'm missing. Remember all of the side plates are designed.
Should I check for shear in the corner welds?
Thanks, in advance

Make sure that the load is 50% of the crane can lift for the boom length and load radius which you anticipate at the site.

For a totally vertical lift at the lifting points, use one of MJCronin's spreader beams at each end of the tank, with another over the top of those two.
Cheers,
