Well, I didn't want to criticize success either, but there were a
number of "I wouldn't have done it that ways" apparent. At a
minimum, the head should have been inverted to drop the CG, the ram
moved back as far as possible, and then the head blocked to the
locked lowered knee.

I knew about inverting the head, but with forklifts at each end of the
trip, the effect on the CG didn't seem to matter.

The problem with lowering the knee is that it lowers the angle of the
chains to the trailer. Instead I put the knee higher up, so you get a
stiff triangle on each side that supports against side-to-side tipping,
which is more of a concern (at least to me) with the base being so much
narrower in that direction.

Riggers in your area must work differently. I've been a party to a fair
amount of equipment moves and when pro riggers were involved they *always*
wanted the knees down. Lowers the CG and why put all that tiedown strain on
a raised and locked knee?

Also, the 5/8-11 eye bolt used was waaaayyyy to long. Proper use of
an eye bolt here would be to run it in until the "eye" touches the
casting, and cut it off, if necessary, to do so.

I would have preferred a proper hoisting ring myself, but as it turned
out the eye bolt was never used for moving the machine anyway. I only
grabbed it off the seller's workbench and stuck it on the ram in case I
wanted to lift off the ram separately someday, using my ceiling hooks.
