Accuracy of CAT scales and are these numbers a sign of load shift?

Only if there's an overweight violation involved. This case isn't that.

 

I realize that, but someone said cat scale doesn't guarantee axle weights, then someone else said they do, then the first guy said post a recent scale ticket, so I did and it clearly shows cat scale guarantees axle weights. That's all I was trying to show.

 

So it’s Wednesday now, have cover the 600 miles to delivery and did you have a load shift?

 

Did you go on the scales with snow on them?

Or was the truck/trailer with snow that melted?

 

The thud was probably either those boxes hitting the front wall of the trailer or the pallets tightening up. It doesn't take much to make it feel like an earthquake! LOL.

I was once hauling a load of engine blocks (Cummins 5.9L) banded onto wooden skids stacked double high in a dry van. Half in the nose, half near the tail. I had the front of the rear set of pallets blocked/braced with 2x4s nailed to the floor of the trailer, but I didn't notice how loose the bands were on some, but not all, of the pallets. Coming off a long exit ramp that wound around for 3/4 of a mile a four-wheeler practically stopped for no reason a few hundred feet in front of me in the middle of the ramp (no shoulders, we were 75 feet up in the air) and I had to get on the binders a bit harder than normal but nowhere near an emergency stop. One of the blocks on top shifted enough to break the band holding it and fell to the floor of the trailer. It felt to me like the whole trailer had gone over the rail and landed on its side!

The next time I loaded at the same place, a third party heat treating facility, I checked the bands and several broke loose at where they had been crimped just using my hand pressure. The load was already on my trailer because we weren't allowed to inspect the load on the dock. I backed the trailer back into the dock, made them unload the entire load and tighten up the bands. They were, of course, mad and refused until my safety department stood behind me and the customer we were hauling them for (Cummins) also stood behind me. I wasn't the only driver that had the same issue with loads out of there.

Several weeks after that when I loaded there again I was in the men's room sitting on the throne and someone turned the lights out on me. I took it as a complement that they remembered that I was the one who had forced them to do their job properly so that I could do mine.

 

I’d say your load tightened up after the harsh stop. Curious as to why you reweighed and why concerned?

 

Deck angle plays into how much moves how fast. I can move over a 1000kg off the front trailer to the drives just dumping the air out of the truck when the drives come off the scale. Just have to wrap a sock or something around the dump valve so they can’t hear the air coming out of the truck.

 

A couple of years ago I amazed a trainee by "changing" our gross and axle weight by how I positioned on the scale. It took a couple tries, but I had a legal cat scale ticket to cover me until I burned off a bunch of fuel and got past the weigh station.

 

Have you checked your undercarriage for any human bodies?
Those bodies used to make a loud thud.
Just saying. LOL. /s
