Gauge Weight SHIFTS?
Topic 26107 | Page 1
I adjust the tandems to where the gauge weight says 34,000, and then a few hours later I'm parked and they say 37,000! This has happened more than once. Does anyone know what the problem is?
You could just be parked on an incline or the parking lot isn't quite level. It doesn't take much with an 80,000 pound truck to shift 3,000 pounds on a slight hill or by putting one set of tandems in a little dip.
Tandems:
Tandem Axles
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

If you have air brakes set then it will read more. Are you parked on flat land? Those gauges I've noticed aren't perfect but they get ya close enough until you find the nearest cat scale
CAT Scale:
A network of over 1,500 certified truck scales across the U.S. and Canada found primarily at truck stops. CAT scales are by far the most trustworthy scales out there.
In fact, CAT Scale offers an unconditional Guarantee:
“If you get an overweight fine from the state after our scale showed your legal, we will immediately check our scale. If our scale is wrong, we will reimburse you for the fine. If our scale is correct, a representative of CAT Scale Company will appear in court with the driver as a witness”
HOS:
Hours Of Service
HOS refers to the logbook hours of service regulations.
All that plus, if you have air-suspension on your tractor and/or trailer, the air can bleed (doesn't take long) from the bags causing a shift in weight balance.
