Option #1:
30' long 3/4" steel choker or nylon, big steel semi tire and rim. 2' piece of 4"x4" steel 3/8" wall or so, larger than the rim. Drop choker through center hole, through semi rim, and around steel tubing. Pull the rim up to the bottom of the hopper, and lift tank. Trip it with a big loader and two chains on the legs.
Using a nylon through the hole risks it getting chewed up, but it will spread out the load on the upper lid ring. I'd probably use steel.
If the loader is big enough, he can hold the legs while you back a trailer under it. If he isn't, lay the hopper on two straps and pick up the whole tank to load. Looks like a farm so they surely have a big loader. If he can't totally handle his end when tripping, because the loader isn't big enough, just tip the hopper enough with the loader, and keep the "bottom" legs on the ground.
A rim on its own is probably large enough without the tire. I can't see the bottom opening because someone has their ugly truck in the way. More than likely there's a slide on the bottom, it will have to come off. We used to have a 4x4 square tubing welded in a cross, with angle iron welded to the top. The angle irons would catch the outside of the hopper- similar to the rim so the cross couldn't slide around. In a pinch I've done it with just a single long piece of I-beam or such, across the opening, but that point loads the ring pretty good, and tends to slide around.
Option #2 :
I have done water tanks with a pair of chokers on a single line. Looking from the top, choke at 10:30 and 1:30. Choke them at about 3-4' down from the top of the tank. You'll have to use chains or another nylon and chain back down to the legs, so the upper chokers bite and don't slide off the top of the tank. Pick it up and is going to naturally tip. Loader would be nice, but I've also just got them swinging on same radius, stick the bottom legs, and follow it on over, using the momentum to bring them over.
Option #3
Long chokers from the hook to two of the legs, also at 10:30 and 1:30. Trap those chokers with another chain or choker with binder that goes around the tank, 3-4' down from the top of the tank. That top tank line is going to have to be tight. As you lay over, that top line is going to want to go "down" the tank, so I'd have another line that went from the top "band" chain, to around the center lid to hold it so it won't go down the tank. This is kind of rigging like you would rig a pole, a choke at the bottom and a half hitch toward the top, the choke on the side so its going to go over.
Option #1 is the easiest way to stand them back up, because once your up, it hangs straight. But if its got a welded on slide gate on the bottom of the hopper, they aren't cutting all that off. If you use #2 or #3 to stand back up, move the lines to more like 9:00 and 3:00 and it will hang a lot straighter once its up, but you may not be able to hold them out there. If you move the chokers to 9 and 3 on the way up, you're going to need a spreader bar. If the guy is going to be moving these a bunch, two three or four picking eyes on the sidewall to roof joint, is the way to go. And he provides the loader. .
However you lay it down, a loader is going to make it 10x easier. But sometimes you have to do what you have to do.
Also, almost all my tripping has been done with 25-35-45 ton grove truck cranes/ or rt's, on smaller tanks like that. So I've always had plenty of crane and those booms are stout so I could kind of "bull" the tank around. I would have concerns about your rig, especially trying to swing / hook it on the ground/ and follow the tank over by yourself. That gets some side load on it.
Tying the trailer to the tank and then setting it over sounds like a huge pain in the a$$. I don't think I'd do that.
