.I am sure that an FG can do that or pretty close to it depending on obviously the C of G of it all, one thing that I feel contributes to the ability of these big trucks to lean seemingly more is that the running gear is so much heavier than an FG lowering the C of G
I hear you! Maybe a crane is not needed, having another rig the same height as the tested vehicle and drive along side of it with some kind of foam to absorb the slow impact, as long as it was close there wouldn't be much force on the other vehicle as it is near its balance point, the other way is using a winch on another truck while lifting one side of the rig up with a fork lift. Hackney I thought had a way to formulate the angle, and to do that he had to get a flat deck wrecker with a tilt deck and used that somehow, cant remember how... or go by the seat of your pants.......rely on your internal gyros to not topple, my guess is that the drivers will reach the limit point before the truck will, now we just need some testers out there! If Hackneys rig can go to 30 degrees than most other should go to at least 90.
Yup that is why I ordered the heavy steel SRW set up. I wish someone had a crane setup that could support my vehicle while I tried something like this. I would really like to know how far I could go. Knowing this, putting a little inclinometer on the dash would keep me out of harms way. I thought I read somewhere that the Hackney could go just over 30 degrees.
BTW these were obviously provided by unicat, but I found them on a site for folks selling their used unicat. I thought these two were a good display of approach and departure angles. I would like to see the breakover pic.
