If possible, much safer to cut a hole in the wall or ceiling and put it in
place with a crane or fork lift. An A-frame lift rig with a trolley might
work too. Failing that, some heavy duty rollers will work…making sure that
the riggers pull the thing from the floor level and from outside the fall
radius of the shield. The latter is what we did last time I was involved in
moving one of these things.
Good luck & be careful!

Subject: Re: Powernet: moving Pb shield - advice needed
There was a fatality from moving a SAM at a nuclear site. I don't have access
to the lessons learned but someone from an operating site should be able to
help. I believe this is very dangerous! You are right, it would be top heavy
and could fall over.
Hope this helps

Greetings All,
We are trying to move a Canberra Model 747 Pb shield into a room and onto its
stand and need some advice. We can get it into the room with a forklift and
even set it onto the stand, but must then move it about 10 feet. We are
concerned with moving it while loaded on the stand as it will be top heavy. We
cannot get the forklift into the room. The unit weighs 3000 lbs and has
lifting eyes.
I am sure someone out there has done this and can give some advice. I would
much prefer to lift the device onto the stand once in the room, but am not
familiar with small enough portable equipment capable getting into the room
through a 36” door and lifting this 3000 lb device. Another way we could do
this is to load it onto the stand with a forklift from outside the room and
then “slide” it over about 10 feet. This does not seem like a very safe way to
do this since it is so top heavy.
Perhaps there are lifting devices that can be rented?
Any advice would be appreciated.
Yours,
Rob
