Damage occurs if the Table lifts and it is loose on the base and that means the table rises and the leadscrew and table gear have side thrust that may cause an issue. Good tables like a Troyke have the table retained on the bottom of the base with a center bearing which restrict table lifting tendencies

A few notes. Two Eyebolts are ideal , as the lifting forces cause them to move to the center of the table which prevents them from sliding out of the T slots.

Three eye bolts however allow the table to be lifted without tilt, which is caused by the handwheel weight. We had Troykes at work up to 36 inches and trying to lift them so they stay horizontal is a chore in preventing damage to Mill T slots when placing them.

You can do two things to keep it level. Make a plate ( 3/8") that has holes in it for T nut studs ( NO end Slots- please !) and weld a tall eye bolt ( like 12" ) to the center of the plate. now when you lift , the table will be like a pendulum and stay closer to level. If you really want to be fancy, here is what we did. The plate (14" round ~) was mounted with 3 or 4 T studs/nuts. A 1/2 "round bar ( drill rod) was placed under the RT and moved until the table could tip either direction . a line was drawn on the plate to exactly match the position of the drill rod underneath , then the rod was changed 90 degrees and repeated . . then the rod was placed 45 degrees to both lines and the balance point gave us the exact balance point to weld /bolt the lifting rod and the location of the handwheel to the plate was stamped.

At present in my home shop, I have a forklift for lifting, but my earlier shop had a RT handling system. I bolted 2x2 Unistrut channels to the ceiling joists and slightly off center from the Mill head. Then I made rollers for the channel and dropped a chain down to my RT on the mill. I fastened the chain to and eye bolt and then lowered the Mill table, thereby allowing the RT to be rolled to the rear of the mill where it was stored ..suspended with chain
