Scale/Weight/Axle Question

Ok, i see where we're bumping heads.. you were referring to the ratio the whole time. I wasn't.. I was just talking about moving the load forward and the shift causing the weight on the bridge to shift forward also.. I don't know how the ratio deal works, it has too many variables to deal with.

 

You have the 5th wheel all the way back, that means the trailer is using the drive axles as a fulcrum, like a sea saw, so when you are heavy on the tail of the trailer, it is lifting weight off of the drives, and forcing weight onto the steers...

I stopped & weighed on Cat scales today. This is what I had:
Steer 12780
Drive 31480
Trailer 32460 heavier on trailer
Gross 76720

Steers: 12,420
Drives: 22,400
Trailer: 24,100 again heavier on the trailer
Gross: 58,920

Steers: 10920
Drives: 35380 balanced trailer, no forcing weight to the steers
Trailer: 35720
Gross: 82020

Steers: 10940 (which is close to the other ticket above)
Drives: 26980 heavier on drives, so no forcing weight to the steers
Trailer: 23920
Gross: 61840

I have seen this before, and moving the 5th wheel forward two spots, may stop the fulcrum action.

 

did the OP ever mention what kind of freight he's pulling?

cuz his weights look like he's pulling liquid.

i hauled bio fuel once. single bore tank. that's the only time i had weights bounce around like that.

 

yeah i double read that one post as in my experience,moving toward the weight issue has put more on that axle.. i was wondering if i missed something by not attending a driving school and also why my overweight ticket count is not even larger than it already is.It would be if i slide everything towards the heavier weight, I have also pulled many loads that took weight off of the steers upon sliding only the trailer tandem.

the 40'spread end dump i pull has to be loaded about 3' from the front of trailer and about 3'+/- from the rear with the heavier loads for my weight to be scaled legally.I have no 5th wheel slide capability as my 5th wheel is blocked,making it stationary then but slideable upon removing the block, when pulling the end dump.it is set up about midways of the rear truck tandems but that is irrelevant to the OP.

i am not sure why the OP is making it so difficult for himself.get it legal and ride. i have never been messed with if it is under gross but a few hundred over on steers.Lucky? perhaps.

not directed at any one driver on here but sliding axles and 5th wheels is not rocket science.it is trial and error so keep sliding and keep learning.

 

which translates into pulling onto the scales SLOWLY and waiting a short span for the liquid to cease movement. OP must drive a really short wheelbase truck. i am getting confused as to what the original issue was so i must go back and read again.

 

the problem with OP. is that his 5th wheel has no more room to slide. he has pics posted. and he's located forward of the middle.

his whole 5th wheel bracket is in the wrong position for his operation.

his only option, would be to unbolt the 5th wheel and top bracket and move it back 1 hole. and bolt it back down. but he's going to be short 1 bolt on each side.

or, the more expensive route. repositioning the entire bracket assembly.

 

i should have assumed as much since the links to his pictures were invalid for me.wonder why some can view the pictures and others can not?
