Scale/Weight/Axle Question

you weighed 12,420 on that particular load becuase you only had slightly less then 3/4 tanks. if the tanks were full, you'd be closer to 12,700.

i took a load from utah to cali, weighing 760 pounds over. i stopped at petro in reno and scaled. i burned off 440 on the steers and 260 on the drives. that was 700 pounds. 60 pounds more to go. i rolled with it. by the time i hit truckee scale which was 35 miles. i was right around the 80,000 mark. 21 miles to cali state line, 15 miles UP the cali mountain to scale.

still trying to figure out the math. but i'm guessing the steers burn off weight 27.5 % faster then the drives.

my next load to cali, was 2250 pounds shy of gross. but 12,440 on steers and 34260 on drive. again hit the petro in reno for scale. 12040 on steers, 34000 on drives. i burned off the same weight on the same travel. almost.


if your 5th wheel is absolutely back as far as you can go. guess your in a dillema.
take a pic of trailer connected to 5th wheel and post it on here so people can see what your talking about. or even just the 5th wheel itself.

 

Mitch, you're mistaken here. It doesn't matter where in the trailer the load is, as far as steer/drive ratio. Sure it will change how much is on the kingpin or the tandem, but only the 5th wheel position determines the distribution of that weight to the steers and drives. Same for the kingpin setting on the trailer, that only determines the split between the kingpin and tandem.

To the OP: Unless you're weighing with dramatically differing fuel levels, I'm thinking there's something up with one of the scales. Also, where is the 5th wheel in relation to the tandems?

 

Been lookin at this...&couple of things come to mind
1-Hammers dead on w/5th setting--been wondering same thing....So you say all the way back...BUT where is that? Just looked at Werener Cascadia here at the Alamo---& from what I could tell---doesn't look like you could get it more n an inch or so past top dead center....

also in terms of fuel...it is helpful to know what the weight split is between your drives&steers...

For example I have mine at 60/40---but that is irrelevant....because that's MY truck which is not anything like yours....just helpful to know how much fuel weight goes on each...

 

have always put the 5th wheel 1 notch forward of center of drives.

freightliners and volvos.

and NEVER have to move it.

really.

once you find the sweet spot it doesn't move.

 

oops, thx for the correction!

 

actually the amount of weight on the drives would affect the weight on the steers. I have noticed this several times. The higher the weight on my drives, the lower weight on my steers.

Think about it this way. What happens when you put a bunch of weight in the back of a pickup truck or car? The front end picks up.

running 34k on drives my steers run about 12k even. running 26k on drives my steers run 12.5k. Granted I don't see the 1k+ the op is seeing but, there is a difference.

 

That behavior totally depends on the location of the 5th wheel in relation to the tandem. Forward of the centerline, weight adds weight, behind it can behave like you noticed.

Grumppy, go to advanced mode and upload the pics.
