Side Slope Measuring Device?

[MisterE]

Hi All,

I'm a novice to 4 Wheeling, as I've said in my other threads most of my other threads my off-roading has been in Dune Buggies which had a super low center of gravity and extra wide wheel base. Well I'm very happy with my H3 but it is BIG change! I know that manual says it can handle a 40% side slope and I am getting ready to go back up to the Sand Dunes. Is there anything out there (other than the good old eyeball test) that you can add to your HUMMER that lets you know when your getting into the danger zone as far as the side slope?

Sorry for the newbie question!

You can get a tilt meter from Trail Duty

There is a link to Trail Duty in the thread below

If I got one I would put a mark at 22 degrees to indicate the 40% rating of the H3.

any hardware store has "angle locators" for pretty cheap...

You can buy a small accurate clinometer at a boating supply store for $10 or so. But clinometers made for boats don't look so hot in vehicles and you'll have to be creative mounting it. The ones for sold for 4x4s showing both lateral angle and incline are usually so small and graduated so coarsely that they don't tell you anything useful. Make sure its dampened or it'll bounce around so much it'll be useless.

IIRC, few months back someone posted a pretty slick one here on the H3 forum that they designed and installed , but I don't remember who!

And I assume you know 40% is a little under 22 degrees.

just stick one of these somewhere

[MisterE]

Sweet Thanks Guys!

Ahh my math sucks...How do you get 22 degrees from 40%? Just curious should I ever need to figure it out for another vehicle.

[NEOCON1]

dont know about that math but have had my levogauge to between 36-38 degrees , scary but not even close to max truck was super stable

[MisterE]

Yeah, I would think that it would be able to go more than 22°. As I said my math sucks that was why I wanted to know how to figure it out but a 40% slope at first I would have figured 90° a 100% side slope and 50% or 45° half, then knock another ten percent off that. I was suprised to hear only 22°.

But as I said my math sucks and I totally defer to you guys as the last thing I would trust to my math would be my H3!

Thanks Guys \ Gals!

The slope % comes from the amount of rise divided by the run.
Example: 1000 ft. rise divided by 3000 ft. run = .60 or 60%

This is the way roads are listed on grade signs.

They use the same method for side slope. 4/10 = .40 or 40%
Calculating the angle gives 21.80 degrees.

The gage must be mounted vertically to be accurate.

Wow, now I am totally lost, when I do it I get 33% for you example for the rise \ run example.

I am guessing the mounting behind the review mirror is a good place so that it reads 0? on level ground.

Sorry for being so dense, like I said I trust the numbers you guys are giving me I just wish I could understand how you get them so I didn't feel so stupid!

[thedieter]

It would be 1/3 = .33 or 33%

You could think of it in terms of the width of the H3, about 6 ft.:
2 ft. higher on one side gives 2/6 = .33 or 33% Hope there are no bumps.

The gage that Neo shows appears to be stuck on the windshield at an angle which induces an error.

Is this a good link for the math for our application?

read thru this thread also , lots of good stuff

good rule of thumb;

if the door handle is touching the ground, the slope is too much

LMAO thats when i back off too

Hey All,

I just got the same gage as Neo. If it is stuck at an angle how much error will it induce? I'm looking for the gauge to tell me if I am getting in the danger zone but I'm not going to be staring at it for an exact measurement. Will the angle make it useless or are we talking a degree or two off, which would be fine. As I said I'm just looking for when I've entered the ballpark of being stupid!

[thedieter]

I am going to have to defer to the experienced wheelers since my only experience is from growing up driving on washboard roads.

I have been following this useful Forum to learn what the H3 is capable of.

You could check how much error is induced by putting the gage at different angles and see what the difference is between having the gage face verticle and at an angle at which you are planning to mount it. It looks like the gage has a ball for the indication so it won't suffer from friction.

I don't know when one gets to the stupid point but the door handle dragging may be it. If nothing is dragging, I can't see a problem.
