(sigh) You sure as hell don't need a tractor trailer at all unless the distance involved requires a LTL freight quote first. It's roughly a couple of tons, amateurs move there own weekend boats that are a whole lot larger and heavier than this with their daily drivers all the time. And I still can't figure out why most seem to think either a proper rigging company or those roll backs are about the only options available. You've provided no real information or pictures of where that lathe is, how your going to get it out into the open or close enough to where it can be picked up and loaded, or how far it has to go to the delivery point. Add the exact known machine weight as well. Pipe rollers, castors or machine skates are only for getting the machine out to where it can be then be loaded for transport. Only a fool would leave them in place during transport. As others have mentioned, bolting it down to wooden beams or a large heavy skid before loading then provides much better stability. All your doing is duplicating what the factory does to ship them when new and for the same reasons. A single or tandem axle flat deck truck with a Hiab might even do it. Check lumber and building supply company's to see if anyone's interested. But there's independent owner/operators with those as well. You'd need that total weight and it's H,W,L dimensions, without those it's impossible for anyone to calculate they can even pick it up and move it with the equipment they have. Failing that, someone with a back hoe or excavator business and smaller truck used for transporting those machines might be able to pick it up, load and do the whole job. Obviously none of these are proper riggers, so exactly how and where to properly pick it up or tie the machine down for transport to prevent any damage is your responsibility. Hell I could rent a 3/4 ton pick up and one of those drop deck hydraulic trailers and move anything myself. A complex move this ain't, it really couldn't be more simple. If you've moved anything like this before then you should have been able to figure any of this out yourself. Since you apparently didn't or refuse to use basic logic, then pay a pro to do it. Christ I've had to first build the access road into where some loads were going and then level it's location out of blasted rock before I could even start to move a whole lot larger, heavier and in most cases much more expensive items than this over terrain no wheeled vehicle could even climb.
