Big LP tank. I had room to load it by myself with the 100 ton. Needed the 70 ton to tandem pick and set it at the new site.
I had a new experience with this one. I rigged up on it, and would lift it pretty balanced, then it would start to lean a little one way, and just get worse. Thinking it was a little heavy at one end, I set it back in the saddles, and repicked. Same thing in the opposite direction. After one more try, I got on the phone with the gas company.
Tank was emptied, but not burned off. But they had pumped it off over three weeks ago. The left over vapor in the tank had been making liquid for the three weeks since they pumped it off, and/or they hadn't gotten it totally empty.
Waited for a hour for a truck to pump the liquid off, and after they removed over 1000 gallons of liquid (4,000lbs weight), it loaded a lot better. The liquid was rolling from one end to the other of tank on me.
I usually use steel chokers on the tanks and no spreader bar, but this tank had just been painted, and it was kinda long. I used the roundslings so they wouldn't scar up the tank, and then used spreader bar to keep the nylons from sliding in. Good thing I had the bar, because with the liquid rolling around, it probably would have slid the straps on me.
