>>As discussed at length before Steve in this context a shaduf is the colloquial word I have used in these discussion for the crane. I even say "shaduf crane". If is using the >>word "shaduf" is confusing to you I will be happy to just say "crane". And look at your design for shaduf's in your thread-these are now "cranes" not "shadufs".
My Shadufs lift water, yours do not. So, yes call them something else. Additionally, all cranes use pulleys. Otherwise, it's not a crane either.

OH yes you do... That remains to be seen...

That's a lame answer. So the Pyramids you are building, are not really Pyramids? They do not need to conform to an approx. 52 degree angle. If you don't conform to a 52 degree angle, with each new level, you run closer to the center, and eventually, run yourself yourself out of building and working space.

Ya, you don't agree. as you have no idea how large the timber would need to be to support 5 tons. 2.5 tons on each end. LOL Before making such comments, maybe you should do a little research. Here: [www.aitc-glulam.org]
Show us where you see a structural beam here that supports 10,000 lbs. [www.aitc-glulam.org]

So once again...How do you keep the other end up (2.5 tons) once you release one side? Please provide us an answer for that, and not some evasive answer like I have already explained that.

discussed at length...where? And, discussing it does not preclude it is a viable option.

>>It should be obvious regardless of previous discussions talking about the very same thing that with this system they would be required to swivel.
Why should it be obvious? To swing 5+ tons would require engineering. It's only balanced part of the time. How wide is your "Shaduf" post, when it is swinging around with mysteriously with a 2.5 ton stone on only one end. How you you resist the tendency for it to be pulled over?
>>No thanks. I've done this with you before.
You sound perturbed at me. Is it because you can't answer the questions in an rational way? Again, how do you release one stone which is 2.5 tons, and swing the other end around with another 2.5 ton stone attached? As I said, it does not float in air. It will just come crashing down. Answer that!
The truth is, there is no answer, as it will not work. Download Sketchup and learn it. It is free, and then you would have a better grasp, as to what you are up against.
