Cannot remove the lead...this is a HPGe detector shield. However...a few things to remember:
1) The shield is not welded to the stand, it is bolted. Need to be
absolutely sure the bolts are secure if you move the shield & stand as a unit.
I've seen these things with no bolts/nuts installed.
2) Make sure the top is secured in place. Do not rely on the weight of
the lid resting on the body of the shield preventing its movement.
3) Professional riggers with heavy lift experience. Worth every penny.
You could take the shield off the stand and move it on a cart (low to the
ground), then lift it up to put the stand under it with an A-frame lifting rig.
That way the heavy part only has to go straight up and down. Same thing can
work with a SAM for that matter.

You may want to think about using furniture movers and slide it on the floor.
We did that with the ARGOS. I HIGHLY suggest you remove all lead prior to
moving.

Following the fatality at Brown's Ferry, the movement of very heavy items such
as tool monitors became an important safety issue. As such, our professional
riggers / high heavy load lift personnel oversee all such movements. Based on
the description of the unit I would highly recommend that any such attempted
movement involve personnel with expertise in this area.

Subject: Powernet: moving Pb shield - advice needed
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
