Axle weight

Can you post a picture off truck and trailer?

 

A tanker heavy on the trailer would need the 5th wheel lowered a little, allowing more weight to be transferred to the drives. That can be accomplished either with a shorter 5th wheel or by lowering the ride height. Just be careful lowering the ride height with your driveline angles. Or, use the air ride leveling valve to raise the trailer slightly, which might be the more preferrable route if you're altering ride heights.

Moving the 5th wheel forward or back only shifts weight between the steers and drives, not affecting the trailer. You need to adjust the front/rear balance of the load inside the trailer, and since liquids find "level", you need to correct the front/rear tilt of he trailer (assuming smooth bore). If you've got compartments, load more up front and not as much in the rear.

 

If you've tried sliding the axles and it still won't fix it sometimes the only solution is to reload the trailer its a real time waster however it will save you any overload penalties. as 1 tonne is a fair chuck of weight to be over if it was a couple of kg i'd say don't worry about it.

 

Tankers generally don't have sliding axles, and it doesn't matter how many times you reload a liquid, it'll end up distributed the same way. Gravity is a ##### like that.

 

Failing all that, could one not put the extra Tone on, or apply for a HML. If its liquid is a pretty measurable conscious choice.

 

The problem with loading less into the tank is that it would take more than a 1 ton reduction in order to reduce the trailer weight by 1 ton. If you're paid by the ton, you really don't want to lose the roughly 2 tons per load just to lighten the trailer up that 1 ton.

 

Fair enough, I don't really understand that but being green I'll accept it. Math has never been a strong point of mine.
My head says if he is going over by 1 ton, than to be legal if he doesn't load that tone, I presumed it would put him at GVM.
