Lifting B'port series I R2E4 BOSS-9

Is there some reason you can't lift it from the bottom skid with slings?

You could also use the week to review the electrical cab and sort out the phase converter or single phase rewiring issue so you're ready to go.

I'd need a sling with a load fork to clear all the cabinets, etc. I don't have one, and he doesn't either.

I'm ready to plug it in as soon as it's moved.

Lloyd, interesting acquisition. Does it use paper tape for instructions?

Are the four bolts that hold the head, to the base, 5/8" in diameter?

Do you have a manual? It should describe an acceptable lifting procedure. Can you call Hardinge to find out? They have some nice guys that could possibly help you. I just spoke to them on the phone yesterday about something else.

Barring that, can you attach lifting ears to the two front bolts out of four, and then loop a chain so that it starts at one ear, then goes up to the hook, then goes underneath the neck of the mill, then up again and to the same hook, and then down to the other lifting ear?

That would seem to leave it in a fairly balanced and safe position. Maybe use real bolts instead of front bolts depending on weight distribution.

If you have an adjustable sling, like one the pictured on McMaster page 1456, you can do that very easily. I have one and it is very versatile.

No, but I can't imagine any bolt bigger than 1/4" grade 3 that would not have a tensile strength several times the weight of any BP mill, even multiplied by the cantilever. If you have 4 of them, I'd say it's a great bet.

It can, but it can load up from a text file. It'll go up to 9600 baud, which sounds like creeping by today's standards, but fast enough for a g-code/m-code block.

diameter?

I didn't measure them, but seem to recall they're 1/2". Hmmmmm....

Only an operator's manual. Nothing technical in there.

Hmmmm... that probably wouldn't work if the bolts are 1/2", but you just gave me an idea. Now I've got to find that roll of 8" wide webbing....

I have several 5/8" load binder chains that will suffice for this small a load.

Of course you're right, but I have this thing about "safety factor" with overhead lifting (and when it's coming out of my pocket if it crashes ).

LLoyd

Key points:

- It's not "overhead lifting", it is simple lifting.

- Lift it a couple inches, then pull the trailer out from under it, then lower it to an inch or two above the ground before any horizontal movement.

I agree with your second point -- that was the plan.

But any time the majority of the load is above head-high, I call that "overhead lifting". That may be only semantics, but in this case, all but about 500lb of the machine will be neck-high by the time we can pull the trailer out.

I got the info I needed (for certain), and the head's plumbing access drafts are a legitimate place to lift. That solves a whole bunch.

Oh... Thanks Iggy, for reminding me that the Hardinge guys are "good fellas". They hooked me up with one of their (by their words) "old- timers" who had a lot of experience moving BOSS machines.

He chuckled a bit, then said that they lift the entire head off (about

He also said that the access drafts "were the standard sling point" for that machine, and much preferrable to getting it up to pallet height with Johnson Bars.

LLoyd

Are they Grade 5? If they are grade 5, their breaking strength should be at least 17,000 lbs each. If your BOSS weighs 7,000 lbs, and with some minimal cantilevering action, with the method I described, the strain on the bolts in addition to their existing tension would be only 5,000 lbs per bolt or so. (it is easy to calculate based on the position of your hook in relation to the center of the column)

It will work just fine.

Should work out great.

I prefer to work with careful men. Optimists scare the chg*t of of me.

Wes

Glad to hear that.

By the way, they are "good fellas", except for one thing.

Try to call them again and ask how much does a collet cost for a Quillmaster angle milling attachment. Have your heart medications nearby (not recommended for people on pacemakers). The price is $440 or so for one itty bitty collet.

Cool.

Lloyd, sorry for ignorance, where are those "access drafts"?

Care to post some pictures of your BOSS?

If you don't have resources to post pictures, I'd be willing to put them up. I'd sure Iggy would also.

Wes

I already host a bunch of "other people's projects" pictures. Will be glad to.

By the way, I got a few emails from happy people who found some hard to find manuals in my online manual PDF collection.

"holes" in the casting, for admitting plumbing, wires, etc.

So... you got the whole raft of manuals for the Series I, R2E4, BOSS-9 machines? (pretty please?)

LLoyd

So thre are some holes that permit hooks to be inserted? (no wires to damage), that's great.

Ignoramus6829 fired this volley in news:VLWdnSWuFtRnnPnUnZ2dnUVZ snipped-for-privacy@giganews.com:

Yeah. Two are _obviously_ for slipping in a sling pole. They're exactly 2" square, on exactly opposite sides of the headpiece, exactly over the center of the base, and no wiring runs close to them.

Two are 2x4, and look to be hand-holes for helping route cabling.
