80 [tech] [weight on roof] pics

John,
If u look at many overland expeditions sites and also Venezula (as they do a
lot of 80s) u'll see some large roof-racks with lots of stuff. Thats not to
say its advisable.
However the gutters can take quite a lot of weight if the roofrack to gutter
mounts are as many and as spread out correctly as possible. The gutters are
reinforced down to the pillars.
Also different racks are going to have different carrying capacity and
different load distibution.
Saying all the caveats its all a guess (unless u get exact specs off ARB and
specific to an 80 and what model/year etc.) until u come across someone who
has had a cracked pillar accordingly. Its wise to put heavy stuff lower down
from a safety and center of gravity point of view.
However I've had quite a load on mine (see photo) which came across the
ocean (Scotland-USA) and then picked up and drove approx 3500 miles. I'd
suspect from of the overlanders have had bigger loads. Check the Venezula
sites, Aussies and African sites (80 group online in SA I believe) and get
some more input.
Just taught I'd send u some pics :)
I got mine fabricated and well worth the money compared to getting an ARB
and more options when u DIY

Hi Roman
A ha very interesting indeed. So the heavier the goods on the roof rack the
more unstable the cruiser is. So all the heavy stuff in the back should be
ok. Im not messing when I say our roads are crap with more bends than a
roundabout. We are getting some where. Next thing I have to do is measure
how many wheels /tyres I can fit in the rear. Also if you put too much
weight on the gutters they will break and you could also crack the pillers.
Geese I wonder what would happen if you turned over and all the weight of
the cruiser was on the roof, pancake time I think and without the jam or
suger.
Thanks

Brendan,

That reminds me of the ill fated expedition by Max Adventure to the
North Pole in 2000. They new it was not advisable, yet they chose to
load their Landrover's roofrack with all the fuel they had. During the
next few days they lost more time on righting the vehicle each time it
hit a soft snow patch and nearly fell over than on moving forward.
Eventually they gave up and returned to base.
Another point of note is that when you drive several hundred miles on
tarmac you will never notice the effect of metal fatigue in the roof
posts. Driving the same distance on corrugations may be a completely
different matter - vibrations are so severe that anything that may
fall off certainly will, including bumpers, gearbox mounts or
roofracks.And yes, in Africa I have seen a cracked A-post or two.

Good point as regards tarmac (heavy loads) v's offroad (much less advised :)
