scaling a spread axle

I would like to know also.

 

i thought you pulled each axle you wanted weighed just to the end of the scale "but still on the scale" like overall weight, then your drive axles on the edge of the scale, then your trailer axles on the edge of the scales, then if you minus overall from the drive axle weight it will give you the weight of your steering axle,then minus your second weight you got (your drive axles on the edge) from your rear axle it will give you the drive axle weight, of course the rear axle weight should be what ever it weighed with the rear axles sitting on the edge of the scale........right?

 

With portable scales they just have you drive each axle on separately because the portable scales are only big enough to weigh one axle at a time.

 

if your on a 3 plate scale you would pull up till you tires look like this ok o --oo -- o o (first plate steer tires, 2nd plate drive tires, last plate both trailer axles) push button tell scale person weigh you and that your pulling a flat and when the tell you to pull up you pull till your tires are like this oo-- o --o (1st plate drive axles, 2nd plate the front trailer axle, 3rd plate the last trailer axle) but i could be wrong check to make sure with notraps or some one else that really pulls 48 spreads

 

Yeah I know how and I think he does, how to pull on a cat scale. But what he is asking is how do you get seperate weights on the two back axles. Because actually you can haul a lil more weight on a spread. What he wants is to get each individual weight on the axles.

 

Nevermind I see what you are saying.

 

I see the problem only if the suspension is leaf spring with no equalizer beam. I assume air ride spreads equalize. In the old days, we had torsion bar trailers with a gear box between the axles to equalize the weight between the spread axles. Man, those torsion bar trailers had 44 grease zerks.

 

it's cool

 

It's pretty tough to overload a single axle on an air ride spread. If you did, you would know it because it would ride like crap. If you are running at 40k on the back all of the time you are loading things too far back on the trailer.
