[Sneap] Radiation Shielding on Wheels?

[jonesn7 at comcast.net]

The Siemens Eclipse cyclotron has two movable shields that each weigh about 16 tons. They are on flat tracks and steel wheels (four total) that carry the weight. I think the wheel trucks are standard industrial items, and the drive motors are not very complex geared units. We have interlocks that both give closed indication for rad reasons and open/closed limit to stop the motors. I would think any good shop could fab up the units to run on steel (I think ours are SS) plates bolted to the floor with a guide track (front and rear guide pins) in the center.
