[ RadSafe ] Need advice Moving large Pb shield

[Franz Schönhofer]

RADSAFERs, folks,

I have serious problems to understand your problems!

During my active years I have moved all kind of superheavy lead shieldings 
an equipment through Vienna, down and up to and from cellars. I never 
attempted to do it myself - simply I am far from a superathlet.... As we 
have specialists for gamma spectrometry, for alpha spectrometry, for LSC, 
for X-raying etc. etc. so why should somebody want to move a 3000 pound 
equipment by his own? There are specialists, at least in my country Austria 
there is a compulsory insurance if any damage occurs during the transport. I 
was amazed, when the transport company brought my several LSC counters 
"Quantulus" down to the cellar! The weight was 1500 kilos, or you would 
rather say 3000 pounds. We have in Radioprotection the concept of Risk vs. 
Benefit. This applies also to the problem you describe!!!!

The only advice I can give is: Hire a professional mover! Good luck!

Franz

Radsafe/Rob Gunter,

     What a cool problem.  Professional Riggers  are probably the right way
to go.  They'll do the job in a day.
If you all decide to do the job yourself, the pallet lifters are pretty
cool.  Make sure everyone wears their steel toe boots the day of the  move.

    Unloading and re-assembling the shield may also be  another way to go.
You're doing the move with the source in place???   Let's be careful out
there.

    I've seen Riggers move lathes and other machine tools  around by
rolling them around on solid metal cylindrical rods.  The trick  is getting 
the
shield up onto that first rod using a crane, crowbars, many
strong people etc.  Then you kind of roll the shield on the rods until  you
get the shield to where you want it to go.  You may need 3 or 4 or 5  such
rods.  Roll the shield slowly.  Don't develop linear  momentum.
Eventually you'll have to get the shield down off the rods.  Again be
careful.

   Riggers do this stuff everyday.  I once saw a rigger dude  pick up a
jackhammer, put it to his shoulder
and drill through a vertical concrete wall.  Amazing.

   Which philosopher said "Give me a lever, and I will move the
Earth!!!"???

   Good Luck.  Hire a good Rigger.

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 8 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
