I saw that come up, great buy! Can't help with the lifting points though unfortunately.

Ideally from the base; if you're using a forklift I'd try 2 slings under where the base/pedestal flares out to support the table, crossing them over so they're on the opposite fork tines so they don't slide up and off.

If you have to single-point lift (crane), the same could be done with a lifting bar with 2 tabs welded to keep the straps from sliding to the middle

Mine has holes through the base for rods to pass through and be lifted from, but it's earlier than yours.

Congratulations on the new acquisition Andre, but that new toy looks seriously top heavy to me. I think that I would dismantle it to the point that it was pretty stable on its base. If that is not practical, then my next move would be to bolt the unit on substantial bearers, and then bolt them down to the trailer. Even better would be to have crossed bearers like the hash key on your phone, and 6X2" hardwood bearers would be about right for that job. If you cut them to be a neat fit in your trailer, there is no way the grinder can move side to side or endways either, and bolt them with 16 mm bolts and all should be good. A length of all thread and plenty of nuts and washers will most likely be cheaper than bolts, and you can cut them to the length required on the job, without the work of having to get all the bolts of the correct length. If the floor of the trailer is a bit light or in poor condition, I would also have bearers on the under side passing under a couple of crossmembers, so that you don't just pull the floor out going around the first corner after loading up.
Elanjacobs method of slinging looks about right in the absence of holes for lifting bars to pass through, but I would just carefully lift it and the bearers, then back your trailer under, I would not want to travel with it on a fork lift for example. If you keep the slings as short as practical, it will prevent them from slipping out over the end of the pedestal as you take the lift.
You could use off cuts of your bearers to pack under the topmost set of bearers where you bolt them down to the trailer floor, to stop any flexing of those bearers. Hope that this is useful, and good luck with the move.
BTW some grinders have the table just sitting on the bed, and not anchored to it. If this is the case with yours, I would lift it off if you can, otherwise pack it up to stop any brinnelling during transit, but it will need strapping down, with opposing straps, so that the table can not just slip through a single strap, I hope that you can follow what I am trying to explain here, get back to me if you need to, Cheers, Tschuß,
Rob

Ropetangler , I understand what your saying I will be using the tandem axle trailer from work so I can't drill holes but it does have sturdy tie rails welded too the frame.
I will be removing the table for transport the seller suggested laying it on its back as that's how he transported it.BETTER TO HAVE TOOLS YOU DON'T NEED THAN TO NEED TOOLS YOU DON'T HAVE

That sounds good Andre, it will certainly get the central of gravity down, just be mindful of the table, pack it away from the slides, but tie it securely to stop it brinelling its ways, get it and yourself home safe.

slinging advice
There is a lot of machinery around that has been damaged whilst it was being shifted.
You can move it as a suspended load, but that is a job for someone with crane and dogman experience.
The safest way to move a machine is fastened to a pallet.
This is why it is a industry standard method.
Elanjacobs method of slinging should work with a fork lift because the upper lifting points are rigid, however I would not do it with a lifting bar or spreader bar from a single point, because if the lifting bar or spreader were to move off the horizontal axis it could easily topple.
Good luck MarkI've become a tool of my tools.

I don't disagree, but wonder if this machine might be too big for a standard pallet. I actually prefer hardwood bearers of adequate size, with the machine bolted to them. If you do lay it down Andre, you really need to know what you are doing, because it will easily go tits up if the rigging is not right, or the machine cant be secured adequately. By that I mean no relative movement of the table and bed for example, and is the machine back surface strong enough and suitable for laying down on timber bearers. Can you sling it in suitable places to both tip it over under full control and then stand it up again when you get it home. Remember when laying down, the machine will be subject to stresses and strains that it was not designed for, as it was designed for it to be upright. As Poloris, Mark says, plenty of machines suffer damage when being moved by people without the right skills, equipment and expertise.
If you do use a fork lift, make sure the tynes are pinned, and cant suddenly close inwards when you have the load, which could cause the slings to slip from under the bed. Also be aware that the load may want to rotate, and that could also present some danger of slings slipping. Be very careful.

Surface Grinding Machine, & Scraping.
Andre
We have not been in contact for a long time & it is good to hear that you are still into all of the metalworking.
It is also hard to believe we did the Scraping Course in Melb Victoria April 14 & 15 way back in 2012,..... hey thats 7 years ago !!!!
A "Lot of water has gone under the bridge since that time".
Since then, I got right into scraping & after scraping your Shaping machine ram, did a couple of my own Surface plates, my Hercus Lathe, & Mill, & a Hercus cross slide for Micheal up in the north.
During the Melbourne course it was great to meet Steamwhisperer Phil, Anorak Bob, & a whole bunch of other enthusiasts.
Noted, Baron J in England was going to Scrape an item recently, so Scraping is alive & well. It has many applications.
All the best.
Bruce

Over The weekend I got the Machine unloaded and in position. I was definitely not using the Engine hoist for its intended purpose and had visions of it failing.
