I may have asked this before, but I have A Project in mind. This
is much simpler than the last time, when I wanted to build 4 humanoid
robots to pick up a shipping container at the corners and move it.
"Hup, hup, hup, ... detail halt!"

What I want to do this time is to just "slide an I-beam under the
outbuilding, attach a wheeled unit to each end, pivot the building and
roll it to when I want it." No doubt "A simple procedure involving
lasers." I'm sure. Somewhere.

But, my question is: load capacity of the units. Assume a GW of 3
tons, does that meant that each wheeled unit has to be able to 'carry'
a three ton load, or can I divide the gross weight by 4, add a "fudge
factor" and hope for the best?

This is one of those things I'd talk to one of the old guys, but I
find I am one of the old guys.

What are the dimensions of the building, is it empty or full, what is
the floor construction and how far do you need to move it in a lineal
direction?

One is 10'x16'by16' high, "framed" floor with 9/8 T&G flooring
glued & nailed. It's rotating 90° and moving ~20 feet more or less.
The other is 10'x12'by10' high. Also going to be rotated, but
moved about 30 feet.
The Big One is 26 by 32 and two stories. It is jut going to get
rotated. But I might add a basement while I have it off the piers.

Once the preliminaries are done, then Ill be scaling down to move
my footlockers around. (I had this idea for a camp setup, using a
20' shipping container as a base, and outfitting the Clanks with
appropriate livery, depending on if I'm reenacting medieval or
Steampunk. But that's a digression.)


What I'd really like to know is: how do I calculate the load
bearing capacity needed by the robot which is going to pick up the
corner.

Are they on concrete or on dirt?

Slab or blocks?

The "easy" way to move them..the smaller two..would be to wrap a
chain around the bases...flood the ground under each one to get it
slick and muddy..and using a dozer ..pull the chain. To rotate..hook a
chain AROUND the base and pull that chain..pulling the building
around. pull from the right to spin clockwise, from the left to spin
counter clockwise. Figure on the 10x16 at 10,000 lbs..empty. Dont try
to move any of them with contents. Alternately...you could..could
bury a vertical.. 4" thick wall pipe about 4-6' deep..and hook a chain
comealong to the wrapping chain..and hook at ground level to apply
motive power.

The other way..would be to rent a large forklift and simply pick the
two of them up, one at a time..and move them to their new spots. The
BIG one...will likely need to be cut in half,seperated and spun.
Moving a linear 24x36...is not..not..not going to be easy. Trying to
move it as a whole with your limited resources..will likely break it
in half. The best way of course..is to a have a house mover come in
and do the job. No idea what they would charge..it would be a pretty
simple job for them..assuming they have some working room.

The two small ones as noted..you could do yourself. And depending on
your construction..be pretty easy to do. The big one..by yourself..is
a mother ****er.

If I were you...Id call a house mover and have them come give you a
price. They are insured. You are not. If they bust em..they cover it.
If you bust em..you are ****ed.

And of course..they have to be empty.
