I had the riggers come in and rearrange all the machine tools in the lab: two manual lathes, 2 Bridgeports, Haas toolroom mill and lathe, Haas VF-0, a Haas turning center, and an Injection molder. Everything got moved once, one of the Bridgeports got moved 4 times as we tried to get the clearances just right.
I was blown away with how easy the riggers made it look, as well as the total simplicity of the tools used: the foreman had a shop made steel Johnson bar. Standard 26 pound railroad bar with a 2" stub welded on the end and 2 super duty roller skate wheels on the sides. Each of the 2 grunts had a dolly made from a 2"x2" x1/4" angle with another super duty roller skate wheel on the side. That's all they needed to move everything except the big Haas lathe! (Haas lathe case was too bulky to allow access underneath)
To move a Bridgeport, the foreman would hook the base at the back, lift it up an inch or so. Grunts would slide the angle iron blocks in along the sides, near the back. Foreman would set the load on the side rollers, go around and get a 1" lift off the front. A bit of a push and off it went. When I wanted the Bridgeport moved over 9" and a bit more angle, it took no move than 3 minutes with not the least bit of grunting and groaning.
The Haas VF-0 had to go down a long hallway and through several doorways. Same Johnson Bar and roller skates.
Did I say I was impressed?
