Cabovers

those SA trucks are always amazing

also very interesting to see high end machines like nicolas and new MP3 SLT tractors working together with MAN 48 700 8x8 from 1980´s

 

those finish laws for oversize loads are very interesting they allow 18ton per drive axle

so rear end of this scania is allowed to 36t or 80000lbs

i am not sure who can offer such rear end know only for scania and mercedes

so this is probably heaviest euro law for weight on drive

here they allow only 26t on 2axles (57500lbs)

 

Hmm. By knowledge you can never exceed 11,5t on drive and if it's a 6x4 maximum is 9,5t per drive axle. Doesn't matter how over sized you are that's maximum. You can temporary to get it going exceed the pressure to a maximum of 19t to get it going.
But that's just how I have understand it, if it's correct I don't know

But the calculations with 36t on the Scania sounds correct by my ears to

 

for oversize loads not normal

here law will allow you to get 7.5+7.5+13+13t on 8x4 tractor

 

More and more OT
Anyway

Some way long back in the brain; Isn't the axle load also based on the distance between the axles on the truck? Or is that something I just got mixed up.

Anyway it's shouldn't differ if it's oversize or not. Maximum axle load is the same what I remember.

 

You are allowed higher axle loadings when speed is reduced.

 

Who makes tyres/tires that have 9t rating on dual fitment 22,5'x9'.

Here we are limited by a few factors on overweight permits.
(1)Manufactures rating.
(2)Tire/Tyre rating.
(3)Law on road.
(4)Bridge formula.

This usually means about 13t and 9t on steering is best you can get.

 

Tyre load rating also goes up when speed goes down. If you want very high axle weights you must use 24 inch tyres, those "arabian style" tyres.

 

Ok, some site to read about it?
Want to get some clarity about it. Tried ake but couldn't find anything good there.

 

as much i know no one

4000kg per tire or 3750 is max

but as Lenny say you can use 12r24 or 325/95r24

they have 4750kg per tire
