roll-over gage

[davez26]

When will I roll-over? I said what the heck, and spent the 8 bucks or whatever for that plastic gage that shows how many degrees to the side you are leaning. The theory is that you look at the gage and say, "Uh-Oh, we're leaning way to much and are gonna roll!" Somebody told me 30 should be the limit.So, for all of you have rolled over, and have the same gage, what is the magic # of degrees?

:eek: :eek: Note: The writer of this post is keenly aware that a plastic gage filled with oil and a ball-bearing is no replacement for common sense in the dangerous off-road environment, and that the gage is merely a tool, not a replacement for wisdom and forethought in a wheelin' situation. :eek: :eek:

That's a good question. I don't have the guage (and I doubt it would be the last thing I would look at while I started over). As you know, a lot will depend on your lift and track (with a little luck tossed in). I would think you could go more than 30 but not much further. I should get one of those guages. Being new to this sport I get real nervous, real quick and my truck isn't that high!

There is some company somewhere that will take your truck and throw it on this jig thing and actually tip it over (and catch it) to determine the exact roll-point...from there, they calibrate your gauge with the exact point where you are screwed.

You could try something similar with a towstrap tied to your frame or something and lifting the truck with a forklift or highlift till it started to roll redface.gif ....

...of course, if you screwed up and let it fall on it's side, you would be the laughing-stock of the ifsja, tongue.gif but hey...we could use a laugh around here. And besides, if you pull it off without ruining your truck, you win 5 cool-points. ;)

Make sure to take lots of pics and inform us of the results :D

well i didnt need a gauge to tell me that i had just rolled, maybe an idiot light that turns on when your truck is on its side or upside down. http://www.gamers-forums.com/smilies/contrib/geno/rofl.gif http://www.gamers-forums.com/smilies/contrib/ruinkai/biglaugh.gif

they got that one bumper sticker thats printed up side down on a friends jeep.

"if you can read this flip me over"

i have one of them meters but never installed it, it came out of a wrecked small jeep, where can i get a wagoneer sticker to put inside of the gauge?

there are too many variables to say that there is one certain degree where you're going to flop. Traction, air-pressure, track, springs, weight, unsprung weight.... so many variables.

the gauge is kinda fun, I think we had my friend's FJ-40 up to 45* but couldn't get it to flop over..

:D Wow I'd hate to have to read the disclaimer that company has for that! :eek:

Just as a general check, what I would do is park on a flat surface, run a string from the middle of the cooling fan to the middle of one of the front tires and then just measure the angle of the string and the ground with a protractor. This is assuming that the middle of the fan represents the center of gravity, but considering that your center of gravity is in three demensional space, a two dementional gage won't compensate for camber and angle from front to rear as well as side to side and how they interact with eachother. So the gage ain't never going to be accurate, so your measurements don't need to be accurate either. But measuring the angle from a wheel to the fan should give you a rough idea to go on. smile.gif

UHHH.....if you are at 29 degrees (safe by your theory) and you drive over a big rock with your uphill wheel, or your downhill wheel drops in a hole while you're watching that inclinometer thingy, what do you think will happen? :eek:
Not trying to be smart alecky here, just trying to prevent disaster. :cool:

i have one of those gauges in the chero, well HAD. i had it over 30 degrees a few times. it is interesting.

Your roll-over point is determined by your COG (Center Of Gravity)

Are you ready to do the math?

As mentioned, under certain circumstances, you could exceed your angle rating side to side if the front or back was higher/lower...so the gauge aint gunna save you from stoopidity....

In physics class we measured the COg by hanging the object from a string in several locations....then you can see where the COG is...it's where the string lines all intersected...so what you gotta do, is hang your jeep from a string. First from the rear bumper in one corner then the other corner then the front corners, etc...then see where the strings were all pointed...that's your COG...have fun tongue.gif

I think you need a passenger to watch the gauge to see at what point it starts tilting really fast. After uprighting the truck, mark that point.

:rolleyes: :rolleyes: Warning: do not take advice from this poster, his truck destructive behavior is not condusive to vehicle safety :eek: :eek:
