If you sling the bed, the center of gravity of the headstock will be above the lifting point, so it can still fall over, and they do!
Attach above the CG and it will be safer.
I put a bar through the chuck and out of the end of the headstock.
At the saddle end I make the bar go into the tailstock and lock it all in position.
Then a sling from near the tailstock and and around the piece sticking out of the headstock.
Lift slightly, then move the carriage along to get the balance right.
Lock the carriage. Make sure the lifting point can't slide along the sling. Once they tilt end ways, they usually keep going till vertical or the ground arrives first.
Make sure the tailstock is securely locked, and the sling can't slide away from the tailstock and muck up the balance.
Use a lifting jib with the fork lift, and possibly a restraining chain to the fork tower guard. Good practice.
Bottom line. DON'T drop it, but lifting it high like this will not allow it to tip over. (unless the fork is not rated for the job!)
Observers need to watch carefully, but keep themselves well clear.
