Your company scale probably needs to be calibrated. Scale at the yard, then immediately go to a cat scale and see the difference.
What happened is the hostler weighed the trailers and it was under 80k, I then weighed the whole set before leaving the terminal and my numbers were lighter then the hostlers numbers. I then was stopped at the scale in Wisconsin and was under 80k, but my meet driver brought it back to his terminal and weighed it and said it was 84k almost 85k. I originally said your axle scale may be off a bit. He just told me that he added the axle weight numbers up and that's what he got. That's why I then asked our terminal mechanic and also a scale repair guy at the truck stop that we meet at and they both told me you CAN add the axle weights up, However its not accurate and that you need a cat scale or 1 piece scale where it weighs the whole assembly. I just want to make sure this does not happen again, I don't want to send a overweight load down the road to the next guy.
Just got an overweight ticket at Cascade locks scale on I-84 EB in Oregon for being 107,000 instead of 105,500. They only weigh one set of axles or axle at a time and will have you reweigh to add it all up if you’re over. Don’t need a full truck length scale to get gross weight. Just add up all axles.
Wow I just went down that road. I'm never up there and I just came back from one load going up there. 84 is a pretty road. I get prepass for almost all scales, rare is the day I go through a scale, no matter how heavy I am.
