This one weighs considerably more. I can pickup 250 lbs, but I had a hard time sliding this one once I got it in my pickup truck bed. We used an engine hoist to load it as there was no way that two of us could lift it. It is programmable and has some type of air lock device in it also along with the servo motor. It is an SMW table and it has an 18" diameter, 1" thick faceplate bolted onto the roughly 12" t-slot face. The additional tooling obviously adds some weight to the table also.
The control manual is dated 1990 so it is from about that time period. I first saw it about 5 years ago and it was for sale then and at that time it was being stored. The plant guy said they used it for one job a long time ago and that was about it.
