Just a note to announce that we're just about ready to start emailing notices for class signups for Overland Expo EAST. It's an excellent lineup, 140 in all, with several all-new classes. We've modified our 1997 Discovery to make it easier on the vehicle for demonstrating roll recovery both with and without a winch. Those of you who were at the west Expo know why we needed to modify it . . .
 
That is kind of a big tease Jonathan...

Expo East is going to be even better this year. Anyone in the area should make a serious effort to get to it and partake in this veritable Cornucopia of Overland Goodness :)
 
This is normally a gentle recovery operation: winch pulling the vehicle upright with a strap wrapped through the rear window and over the roof, while another strap wrapped the opposite direction is hooked to a triple-pulley rope and a manual brake, so the vehicle sits up without slamming onto the opposite-side suspension. Unless the brake operator forgets to let off tension when the winch is pulling . . .

We repaired the roof, but since we need to do this demonstration repeatedly, we had a roll cage made that fits behind the front seats, so the recovery gear can be connected there.
 
NICE PICTURE :D so there should be a disclaimer, "This vehicle equipped with recovery bar to prevent roof collapse during recovery."
Why can't you just hook a strap onto the axle or slider to flip the vehicle over, rather than the roof? If a vehicle is on its side or on its roof how would you feed the strap under? This seems odd maybe I am not understanding the scenario here.
 
Axles are a bad place to use for this recovery scenario, could just yank it out of the vehicle. My preferences based on personal history would be to sliders/ frame. Obviously the recovery crew didn't know Mr. Murphy would be helping?
 
The roll class actually incorporates multiple lessons. There's the actual recovery, but also general winch use, force multiplication with the manual rope and pulleys on the other side (actually how we tip it in the first place), and assessment of recovery gear and working load limits. We explain numerous ways to recover a rolled vehicle. Pulling on the frame (not axle) is one way, but on a unibody SUV that's generally not possible. Straps through the window and around the roof work on almost anything, and they're rarely completely blocked. Also, the higher you pull on the vehicle, the less chance it will simply slide sideways. We also like to tip the vehicle back gently rather than simply letting it drop—again, we need to do this repeatedly with this Disco. If someone were doing this once with just a single strap, and letting the vehicle drop, there'd be little danger of crimping the roof.
