Hi there guys. I posted this topic yesterday hoping someone might have an practical, as built, quick assembly drawing or idea of a gantry in order to build a tank bigger than 5m in diameter. hence the parameters of between 5 and 10m. I need the frame to be plus minus 16m high. What i didn't add in my previous post is the exact diameter (inconsequential really) but which is of relevance is the maximum weight it needs to lift.12,000 to 14,000 kg is the maximum weight i will need to lift with this frame.The remote locations where these tanks are to be erected makes using a crane too costly mr JC. A crane must be present at the time of site establishment but even that time needs to be as short as possibleI've included  a hand sketch of more or less what we need.GVini-SA Engineering2015-10-18 22:47:25

I still don't know why you think the diameter of the tank is of no concern.I'd put lugs on the tank and attach it to the frame shipped as one complete unit.  The crane lifts the unit into place and you're done.  Temporary, tack welded pipe, can be used to keep the frame square along with wood blocking to keep things from shifting as it is transported to the site.It would have been better had you continue to post in your first thread regarding this subject rather than start a second, virtually duplicate, thread.  Less confusion for those wishing to follow the conversation and it keep all the pertinent information in one place rather than spread between two threads.
