    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.

    11,000+17800=28,800. 44820+28800=73,620. Yep, it’s legal

    If you're not hitting a scale you can run it till the tires pop for all anybody truly cares. Old school flatbed doesn't really care about weights. Only how much you're willing to haul. That's in regards to any old trucker management. Sure it's different today, but not THAT different.

    In other words, it’s only illegal if you get caught?

    I was just feeling like being honest. I'm typically a stickler for rules, but there's certain things about the industry, particularly flatbed, that you might be surprised about as a newbie coming in.

    Something about your numbers doesn't add up or its just past my bedtime... 46000lbs on the trailer axles, which is a spread axle, but only 16200lbs on the rear trailer axle? The spread should be close to the same on each axle. And if it was 46000 on the spread thats way over weight. You need to move the load forward a bit.
    Second thing. You said this is a half a mile haul down a back road? Don't worry about the mule just load the wagon. Sure it's not legal and all that but come on.. I might not even put on my seat belt for that trip

    sounds like those north East Ms loads out of the port. Some of there old day loads. 165,000 but then again no state roads. And only 6/10th of a mile haul.

    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.

    Is the scale elevated? If you’re going down a ramp your last axle will be light as you’re pulling off.
