Rollover angle??

[corsair23]

off camber scares me the most. i think i need to start on slight off camber situation and work up the comfort level. i find the hardest part when you have to turn uphill while off camber like in the photo above.

YIKES

To get him down the trail leader actually had him turn down hill so the ass end would swing down and not up. This was after the rig was strapped and then attached to a vehicle at the top of the waterfall via a winch line. Then they were able to lower him down gently.

To get him down the trail leader actually ....

good trail leaders are invaluable

 

[GXO]

I would have tied off to a truck up hill, locked the rear locker, and done a dig to swing that ass back on the trail.

 

[IBCRUSN]

Is this you?

Yep, that would be me with Jim B. from SROR riding navigator.

Nice to have a trail leader with Army recovery experience eh?

You're not kidding.

I would definitely be pulling pieces of seat from my bum if I were in that situation.

No shark fins or stains but it did get my attention.

That was the problem, the person spotting me had me turn uphill and since gravity is constant the front slid downhill.

I felt much better when Brent and Nathaniel had me hooked up. to both of you guys for quick thinking.

Might have worked if it was dry but the waterfall was pretty wet and the sand was like ball bearings. Just like Chevy Chase "It's all ball bearings."

For those that weren't there this is what happens with less than stellar spotting. At any rate, the moral of the story...use only one spotter (two with different ideas is bad) and make sure they know what they are doing.

Oh yeah, thanks for posting up the pic. It doesn't really do the whole experience justice, it was right at 30*. The wife was only slightly amused

Agreed the pic doesn't do it justice at all...Hard to get a good idea of really how high you are up on the waterfall at that moment

If you want some high res versions of what I have just drop me a PM with an email addy. I think I have some video of it as well that I can share once I get it DL'd

My Dad's was an old FJ40 owner/wheeler back in the late 1960s and one piece of advise that he gave me has saved by bacon more than once.

If you start to roll, turn into the roll and give it gas.

It seems so simple, but all too many people don't know about that simple manuver. Sometimes you only have a second to react. But many people don't do anything or turn the wrong direction, making the roll even more likely.

I was coming down a hill one time and the rear started swapping ends with the front. I was on two wheels with half a second to spare, when I remembered those words. I turned as hard as I could into the roll and floored it. I ended up coming down the hill faster than I wanted, but it was at least on 4 wheels. It's the only reason I'm here today.

Won't work every time, but it may save your life or at least bodywork. Just my 2 cents. Thought it might be appropriate for the thread topic.

I managed to roll a two wheel drive Tacoma at 0 degrees. Rallycrossing I pitched her sideways into a corner, caught a rut sideways and she went up on the drivers side about 30-40 degrees, countersteered into it, foot still to the floor, and brought her down. Only problem was with an open diff, the tire in the air was spinning about 100mph and when it came down, up and over onto the passenger side. Hate having to brace myself to not fall on passenger when unbuckleing.

How is this relative? Well it just goes to show that speed and bumps have as much to do with if you roll as the angle you're sitting at. I wouldn't doubt that if you put a cruiser on a big plate and started tipping the whole plate, you might get 40-45 degrees before it tipped. Do the same thing moving, it's a different story. Do the same thing on a trail and bump on a rock, and over you go.

I've found my passengers tend to get scared before I do, and I probably get scared before the truck is going over. So listen to the screaming of your passengers, it's a better warning than a lev-o-guage.

Well done fella's. As already stated its all feel and knowing your rig. When I first got my 80 I always thought I was gonna roll it or worse. After getting to know her I have found that she can do alot more than I first gave her credit for and thats a good thing.

My LX450 isn't my off-road vehicle, but this is in my 4Runner..not sure how far over it is:

next time, put the tire on the other side, eh...!

far enough for me to put a crease in the center of my leather seat!

Finally have my CM07 vids uploaded...

Here is a link to the video of IBCRUSN on the waterfall...Sorry I don't have any video of him getting into the position but suffice to say there were a lot of "OH S%*Ts" shouted before the camera started rolling .

Knowing your rollover angle is good to know. To be usefull, people just have to realize that is is a STATIC rating.

 

[BUSTED100]

the mirrors will stop you, most times

 

[IBCRUSN]

corsair,

thanks for postingup the vid. That shows a much better feel than the 2D pic.

This discussion is interesting and there is some useful info. Could have saved some time if you asked my brother! He knows about tilt plus momemtum. He also knows how to get thru a shrunken window quick. ATF in your hair helps you slide out!

 

[BrotherRob]

Put one side on a lift and raise it until it flops. You'll know exactly at what angle it rolls.... when its standing still. Of course, then you will already be screwed. The angle doesn't much matter because if you roll you will almost always be moving and the momentum will increase or decrease the angle at which the truck rolls. Mine was on nearly flat ground but the front wheels dug into soft ground and the momentum carried it over. No tilt-o-meter will be accuate when moving and cannot take into account the entire situation. Use your guts and experience, if it feels bad, it probably is.

Apologies for resurrecting an old thread but the title covered my exact question. Unfortunately the answer is not to be found in the thread.

I was just on a short adventure course in Scotland using new Landrover Defender 110's. As part of the "experience" we had to drive over a rocky course for about 100' in both directions at a 39 degee lateral angle. I've never experienced pucker factor quite like that before! The instructor said that the Defender is rated to 45 degrees at slow speed.

I'm not here to argue about how much or little the degrees matter (which seems to be the subject of most of this thread).

I am, however, curious if the 80 had a rating out of the factory and, if so, what it was/is?

 

[PKP80]

I will have to agree with Wrench. For the most part I think anyone who has rolled will agree that by the time you realize you might have pushed the truck too far it's too late. whether slow or at speed, in the rocks, or in my case the sand. Furthermore, there are so many factors such as your COG, the trail you are on, how fat the person sitting on the side that you might roll towards is, etc.

GIve it a shot and let us know if you agree.

the off-camber is definitely way up there in terms of what makes me uncomfortable. Something about it being so different than our regular daily experiences I guess. Interestingly, though, you get used to it eventually if you go about it in small increments (not necessarily a good thing if you get *too* comfortable with it...).
I think off cambers are definitely worth practicing and getting used to , though, because if you suddenly find yourself on a serious slope and you have no experience, it's just too easy to panic and do something silly...
