Weighing a spread axle

Many issues on new job but overweight on 1/2 mile of back industrial roads from yard to company property still bothers me.

What I am hauling is aluminum billet 7 inch rounds weighing about 790 each. Currently they load 72 logs bundled on 4s and 5s. Gross weight is about 53800 plus trailer. No matter what that over grosses me.

My boss and the supervisors where I am on contract for their local loads are all old truckers now in management. I want to find an answer and show the math as well.

I normally have 5 trailer loads a week all between 53800 and 57800. I think adding a sixth load is the easiest but I cannot get the math right after scaling it.

I did two loads and drove across the scales writing down numbers as I crossed.

Str. 10200............10300
Str/drv. 29800...........32640
St/dr/1st 59680.......... 69900
Both............................... 46000
Last trlr..........................16200
All. 82200......... 82200

So the load was almost exactly stacked each time judging by strap locations. I did not move the ratchets between the loads and one load was about 18 inches different from the other.

The only scale I have gives only one weight not individual axles. My first mistake was taking the job knowing equipment was bad and there may be overloads. Did not know it would be 5 times a week overloaded. Next I used the standard axle calculator online like sliding tandems.

Now I am new to flatbed but returning to trucking and by all means not a newbie. I can take some gruff but also would appreciate some solid advice.

What i need to do is haul 360 logs weighing about 747 pounds each. Currently it is 72 per load maxing 53784 gross over 5 loads. If I cut it into 6 loads it would be 44820 pounds gross. Can I make that work sharing the weight between drives and both spread axles? The trailers are Premier leases 48 foot with empty weight of 11000 pounds. Truck is old International sleeper. 17800 without trailer.

 

This is why I posted. I cannot make sense out of the numbers but 3 loads all weighed about the same. Trailer axles almost always 46000, steers always 10400ish and tractor almost always 33500ish. Last axle weight I think is off as I am off scale at an angle.

I have been talking with a few of the others hauling. Most OTR will take 52 to 60 logs and the scale out at 79500. Most know their trailers and have it stacked well.
