35 degress

[NCpaj]

Ive read in the tech articles and in my pajero manual that the maximum angle the pajero can be driven on is 35 degrees. Why only 35. What happens after 35 degrees.


The only real time ive driven for and extended period of time over 35 degrees was up a step fire trail and the g/box freaked out and fel out of 1st low and engagded reverse as well

I think they needed a figure, so they picked 35 degrees. Beyond that, I guess it could struggle for traction on climb/descent, and there's the roll-over prospect on a side slope.

It's a general guide, not a hard and fast rule.

Yea, the 'O dear - I think i just soiled my pants' rule usually kicks in about then... !!

after comming down a long 35 ish slope i was followed by a bit cloud of smoke, ok it was more of a small cloud. but i point is that the oil moves and doesn't reach where it's needed at those angles. one of the more techy guys and fill in the huge gaps i have left.

Hava you actually measured that slope. Or was it seat of the pants feeling. 35 degrees is hell of lot steep. If it was a 2nd then usually its about = 2 * actuall slope. One would be really hard pressed to find slope over 35-40 degrees this side of the rock face. Generally loose material cannot creat slope over 40 degrees it will just colapse.

the pajeros have a built in inclonomiter and i have seen one hit 40 degrees (it was in zoot's lwb he was to busy reversing down a hell of a steep fire trail to be watching it.

yeah i got one of those incilometers and from memory it said round 35' . And yes i was sh*ting myself cause i had to make it to the top or reverse down.

I do these kind of angles on a weekly basis for my job.
You are correct in the assumption that loose material (angle of repose) is around 35 degrees for sand and 37 degree loose rock (Mine surveyor talking here) And you are again right in saying angles feel twice as bad as they really are

I get to drive down these angles in a sand mine all day long!!!!
You have BIG problems getting up the dunes anything above 17 degrees.

Um, while I would like to bragg of being able to drive up 40deg slop and reverse down again. It was more like 30deg. sorry Matt.

the slope might have been 30 degrees most of the time but comming of the last hump (the first one you reversed off) it was on 40 degrees, if only for a second. but your right i'll shut up now

One other factor is suspension. Climbing steep hill front suspesion relaxes while rear is compressed which can lead to perception of steeper angle than it actually is. I'd say 5 degrees or more is not out of the question. Same happens down hill and traverse.
