As the others, invert head, lower table as far possible, move table close to column, centre table length wise. Put inverted head about centered over table. Remove horizontal aurbar supports from ram. NOW, check pivet turret locking bolts? or such, tighten firmly. Make sure ram will not move or pivet. Gently tighten all locks for table and knee. Remove all handles and hand wheels if possible. Put horizontal aurbar supports and handles/ hand wheel in truck before loading mill.
Now load mill onto my trailer parked close to yours.LOL. When think you have unit tied down well, add a couple more ty downs etc. Before moving make sure ram will not move, a strap or 2 tied back to the column just in case. Some where I read about moveing a mill and the ram came out while moving, locks were not holding. Good luck with the move
