CAT scale terminology

We have been wondering about our weights and finally went to a CAT scale. We didn't have time to make "3 independent passes", nor did the young kid behind the counter have any idea what to tell us about how to weigh a TV/TT. So, we just went through once, all hooked up. The results we got aren't using the terms that I've read about on this blog ie: tongue weight. These are the terms they used: steer axle, trailer axle, gross weight. There's a space for drive axle, but that one says zero.
How do I equate these terms to ones that I can relate to?

Sure wish you could have done some reading before. Do you remember what part of your rig was on which scale? Usually, I look at the scale, It will have 3 different areas. front is steering axle, second is drive axle, third is trailer axle.

You should make sure you stop in the middle of each of those areas.

You may need to take the truck back, w/o the tt and weigh the steering and drive axles of your truck.

Then you can do some math and determine the tongue weight of the trailer the combined axle wt of the trailer and also compare the loaded and unloaded weight of the steering axle. ( It should be within a hundred lbs, loaded or unloaded if the wdh is setup correctly)

All this is assuming you can remember what you weighed on the first pass. I always keep them available for comparison. You should check it every couple of years to see how much junk you are adding to the load.

Look at this: http://catscale.com/how-to-weigh

You still have usable information, just not refined totally. Your steer axle of course is the as the name implies, your front TV axle. The trailer axle weight was measured on the trailer and is what the trailer axles are supporting less the tongue weight and your gross weight is everything together.

The only info you are lacking is the rear TV weight and tongue weight. My guess is that a little basic math with the figures you have should put you in the ball park for the weight on the rear of the TV.

While I have thought about weighing mine, I haven't done so yet, so you are way ahead of me!

Thanks for responding. Do I assume that since I don't have a weight for the drive axle, that none of the wheels were on the middle scale? Maybe the entire truck was on the first scale and the trailer wheels were on the last scale? My steer axle is 6060 lbs and the trailor axle is 5660lbs. The gross weight is 11,720. We never use the truck unless we're towing the trailer and we don't live too close to a CAT scale. Maybe one of these days we'll just make a special trip with the truck and try again. I did have the copy of the link to the instructions with us, that's why I asked the attendant about making independent passes and he said no, not necessary- just push the button and come back inside! I knew it wasn't right!

Yes,
Sounds like your truck was on 1 scale and the TT on the 2nd or 3rd.

Just chalk it to education and experience. Next time you will be the expert!

CAT scales are "triple platform" scales.

You need to follow THIS link to weigh for simple axle weights.
http://catscale.com/how-to-weigh

IF you want the tongue weight, weigh as shown at CAT scale site, then drop your trailer and weigh just the truck.
Combination "drive weight" MINUS the "single vehicle" drive weight will be your tongue weight.

You should weigh WITHOUT WEIGHT DISTRIBUTING doo-dads attached to get accurate axle weights because of the changes they cause.
Hook them up and weigh again if you wish to change/adjust.

Weigh fee is $12... then $2 for re-weigh.
Go in and get your ticket before re-weighing so you will have the ticket # for the re-weigh.
