That sucks for sure. I had a similar thing happen the last time I took my cab off.
For starters I didn't use chains. I wanted to try something soft so that if it worked well I might be able to put it back on that way. I tried ratchet straps... They stretch. As soon as I moved the crane the weight shifted. Then I was at the point of no turning back now. Went up some more it got worse. I got the front corner to rest on the transmission so I felt comfortable about it hanging for the moment. Got some more ratchet straps, gave it a lift/shove to get it closer to the right weight distribution, strapped it to the crane.
Then the neighbor drives into his driveway...so I grabbed a couple of beers out of the fridge for bait and lured him over. I felt better about having an extra set of hands on it to steady it. It stayed straight coming the rest of the way. I rolled the chassis out and got it down on jack stands without wasting any time.
When it goes back on I will use the old four man lift.
