brighouse shed Posted December 1, 2010 Share Posted December 1, 2010 I can find loads of entry exit angle detail but not side roll angles. so like those old london bus demos with a protractor on the front, what angle can my 90 lean at before becoming a 76 cheers Quote Link to comment Share on other sites More sharing options...
western Posted December 1, 2010 Share Posted December 1, 2010 you will loose your bottle before the LR falls over, best to aviod side slopes whenever possible. Quote Link to comment Share on other sites More sharing options...
Henry Webster Posted December 1, 2010 Share Posted December 1, 2010 Static tests are a bit pointless as ground conditions are never even. LR used to quote a figure but gave up years ago. Have a recollection of it being 40 something degrees. Quote Link to comment Share on other sites More sharing options...
martyn668 Posted December 1, 2010 Share Posted December 1, 2010 I don't know the figures, but a few years ago at Billing the Camel Trophy club put on a display, where they emptied the oils out of a 110, and then tipped it over slowly using a winch (one on each side, so that it went over slowly until it tipped). I was absolutely amazed at how far over it went - as a previous poster wrote I would have bottled at about 25% of what it actually managed. So the carefully considered answer is a very, very long way over!!! Quote Link to comment Share on other sites More sharing options...
martifers Posted December 1, 2010 Share Posted December 1, 2010 We rolled my 90 over at Driffield LR Show this year and was also amazed at just how far they will go before going over. Not sure on angle though. Sorry. Quote Link to comment Share on other sites More sharing options...
moore101 Posted December 1, 2010 Share Posted December 1, 2010 landrovers were intially stated as being capable of 30degrees as a safe operating angle. it was then advertised as being possible if careful to turn one round on a 45 degree slope. that was for series vehicles which with the softtop and lack of dash and creature comforts probably have a lower centre of gravity. i think 30degrees is probably a safe angle to operate at but remember to always drive cross slopes nice and slowly and never be tempted to steer upwards. and others have said, the driver will normally bottle it before the vehicle falls over.

ajh Posted December 2, 2010 Share Posted December 2, 2010 It is supposed to be 45 degrees, I'm aiming for 60 degrees once I get my supplemental air-bag system in place with individual 4-corner forced articulation. Quote Link to comment Share on other sites More sharing options...
brighouse shed Posted December 2, 2010 Author Share Posted December 2, 2010 45 degrees..................this driver's bottle will be gone long before that point, wouldn't fancy that forwards. Quote Link to comment Share on other sites More sharing options...
winton Posted December 2, 2010 Share Posted December 2, 2010 Agree with you losing bottle first. Parking on a Hugh curb in a defender with big wheels on is exaggerated. Often you'll think a slope is not possible, get out and realise your literally just a bit of vertical centre. There's no official angle quoted as said but it's suggested to be between 35 / 45.

ScottinAZ Posted December 2, 2010 Share Posted December 2, 2010 I have always heard that it is around 40-45 degrees. Here is the US, some Land Rover dealers have "tracks" used to demonstrate the capabilities of Land Rovers. I seem to recall the one at North Scottsdale shows a side angle of 40 degrees. The one time when I was on it at 40 degrees, one is looking nearly straight down or so it seems. Quote Link to comment Share on other sites More sharing options...
hobson Posted December 2, 2010 Share Posted December 2, 2010 I would have thought that at extremes, the amount of stuff in and on the vehicle will make a big difference. if the vehicle has a lot of stuff inside on top of the seat boxes, or a lot on the roof, that would have a decent effect on when it goes over surely? I'm sure i read on Brownchurch's site that the angles for fully laden vehicles were a fair bit less.... Quote Link to comment Share on other sites More sharing options...
nicks90 Posted December 2, 2010 Share Posted December 2, 2010 i got stuck at a play day not so long ago in a ditch - slid into it - and my "O-carp-ometer" on the dash read 35deg. I can honestly say i was terrified and positive it was about to fall over, when i finally climbed out to assist fixing the recovery rope on... it looked pretty lame. Being inside is MUCH worse than being outside. I trial my 90 alot and dont mind sideslopes - but 35deg was horrible and i would have definitely bottled out if given the opportunity.

M&S Posted December 2, 2010 Share Posted December 2, 2010 As mentioned above, terrain is important. You can be at 30-40 degrees quite happily on a test track, but drop a wheel in a hole or hit a hump at that angle and you could go over really easily. Had mine at 27 degrees (Disco 2 - measure angles on photo, sad I know!) and that was about as far as I felt comfortable to be honest!

Dave W Posted December 2, 2010 Share Posted December 2, 2010 There is no one angle but, as has already been said, it's usually the driver that bottles before the truck rolls. Suspension lifts, high mounted spare wheels, roll cages all typically reduce the angle the vehicle will cope with. The taller your vehicle stands and the higher up the weight the more prone it will be to falling over. Offset wheels with wider tyres can, on the other hand, reduce the centre of gravity and hence improve the side slope angle the vehicle can cope with.

Biffo Posted December 2, 2010 Share Posted December 2, 2010 We had both the 90 and the disco 1 do the same bit of ground, the 90 was teetering on the brink of going over at 40º, whereas the disco seemed more happy, possibly due to the wider footprint (& 30mm spacers on each wheel) Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 2, 2010 Share Posted December 2, 2010 The green bible for the Series quotes 45deg, the Defender they revised it to something like 35deg, I think mainly to discourage overly enthusiastic idiots from bouncing along at 44.9deg and then complaining when it tips over, as I can't see a Defender being that much worse than a Series. But, as all the replies above state, in reality it entirely depends on what you're doing at the time. Quote Link to comment Share on other sites More sharing options...
western Posted December 2, 2010 Share Posted December 2, 2010 defender should be better than a Series on side slopes because the axle track is a bit wider, but the different suspension systems will have a effect too. Quote Link to comment Share on other sites More sharing options...
Maverik Posted December 3, 2010 Share Posted December 3, 2010 I found this drawing (I like drawings) of a 109 some time ago gives you the tipping angle of 45 degrees. Quote Link to comment Share on other sites More sharing options...
JJB Serenity Posted December 3, 2010 Share Posted December 3, 2010 I was at about 45° when mine started to tip. I didn't get into that position by choice, rather by bad driving won't be in a rush to get to that angle again, as Western says, you will begin to poo yourself as you approach 40° Quote Link to comment Share on other sites More sharing options...
